All of us at Central Coast Software appreciate your support, and we promise to do our best to provide high quality programs for your Amiga. Quarterback is a very fast, flexible hard disk backup and restore utility program for the Amiga. Using Quarterback is like buying insurance. if you are lucky, you'll never really need it. But if you do need it, you'll be glad you have it. Words can scarcely convey that horrible, sinking feeling you get in the pit of your stomach when these nasty words flash on your screen: VOLUME DH0: HAS A READ/WRITE ERROR It's enough to make a grown man cry! But never fear -- Quarterback is here, ready to take charge and turn this hopeless situation into a game you'll win every time! Here is a quick summary of Quarterback's features: * Backs up 20MB FAST -- in about 30 minutes * Works with all AmigaDOS compatible hard disk drives * Uses two floppy drives, if available, with automatic switching * Backup/restore options: Full drive Selected subdirectory Individual files Incremental by archive bit or file date * Includes/excludes files by name and/or wild card * Provides easy subdirectory access * Catalogs files automatically * Estimates the number of diskettes needed * Validates diskette writes (optional) * Restores original file date/time stamp * Prints backup/restore report (optional) * Formats diskettes automatically * Automatically numbers diskettes and verifies their order * Beeps for floppy change (optional) * Handles disk errors in a friendly and logical way * Runs interactively from Workbench or CLI * Accepts batch command files from CLI * Provides AmigaDOS access * Is not copy protected HARDWARE AND SOFTWARE REQUIREMENTS Quarterback runs on the A550, A1000, and A2000 Amigas. It requires a minimum of 512K RAM, and one standard Amiga 3.5-inch floppy disk drive. Quarterback uses two floppy drives, if available. Quarterback backs up any hard disk drive which appears as a standard AmigaDOS file-structured device. In fact, the program can be used to back up files from ANY valid AmigaDOS file-structured device, including hard disk drives, local area networks, ram-disks, or even floppy drives. Quarterback required AmigaDOS V1.2 or later. INSTALLATION Quarterback is not copy protected. We encourage you to make one or more backup copies of the Quarterback master disk for your own protection. But please do no give or sell copies of Quarterback to other people. Before you install or use Quarterback, please read the READ_ME file on the Quarterback master disk. There you will find the latest changes to the program, if any, and any corrections to this manual. And don't forget to send in your postage-paid warranty card if you want to be notified about any bug-fixes and/or product upgrades. You won't hear from us if we don't hear from you! You can copy Quarterback from its master disk to your hard disk or your working Workbench floppy disk, as you wish. Drag the Quarterback icon to the drawer wher eyou want it, or use the CLI copy command to move it and its icon. Remember this: keep a copy of Quarterback on a floppy disk in case your hard disk fails! You'll need Quarterback to restore your files to the hard disk, but if your only copy of Quarterback is on the hard disk...well, you get the picture. DISASTER PLANNING Most of us hate to "waste" all that time backing up our hard disk drives. But we all know, usually through our own bad experiences, how necessary this really is. Quarterback was designed to make the process as painless as possible. The easiest way to reduce the pain is to perform a full backup only occasionally, perhaps once a week or once a month. Then use the "incremental" features of Quarterback to backup only those files which have changed since the last backup. The AmigaDOS archive bits can be used to find all files which have changed. or you can include files by file date -- those which have a date later than the previous backup. There are two schemes using the archive bits for incremental backups. The two schemes differ in the number of sets of backup disks you must maintain, and the speed of the backup. You should choose one of these schemes and stick with it. Backup Scheme 1. This scheme uses only two sets of backup disks (one full, one incremental). However, the incremental backups take longer than those of Scheme 2. 1. Once each month make a full backup to the "full backup" set of disks, and set the archive bits. 2. Between full backups perform incremental backup of changed files to the second set of backup disks, BUT DO NOT SET THE ARCHIVE BITS. This way you can do the incremental backups to the SAME SET OF DISKS each tme. By NOT setting the archive bits, you are guaranteed that you'll get ALL of the tiles which have changed since the last full backup. But each incremental backup will take at least as long as the previous one, since you are always backing up all the changed files. Backup scheme 1 has the advantage that you have to maintain only two sets of disks, and restore, at most, two sets of disks; the full set followed by the incremental set. And to find the latest version of a particular file, you have to check only two sets of disks. Backup Scheme 2. This scheme uses many sets of backup disks (one full, many incremental). However, the incremental backups are faster than scheme 1. This scheme also works with file dates instead of archive bits. 1. Once each month make a full backup to the "full backup" set of disks, and set the archive bits. 2. Between full backups perform incremental backup of the changed files AND SET THE ARCHIVE BITS. This way your incremental backup will be short each time, BUT YOU MUST MAKE EACH INCREMENTAL BACKUP TO A DIFFERENT SET OF DISKS. Backup scheme 2 has the advantage of speedy incremental backup. But you must maintain separate sets of incremental backup disks, which must be restored in the exact order they were created. And to find the latest version of a particular file, you must search many sets of disks. Of cours, with either of these schemes, remember to save the backup report with each set of disks, so that you can easily find the latest version of a file. To ensure the integrity of your set of backup disks, we recommend using the "Read diskette after write" option at least the first time you use the set of diskettes for backup. However, this does slow down the backup process. An alternative is to preformat your diskettes using the AmigaDOS Format program. We also recommend using alternate sets of full backup disks, so that you always have another full backup set to fall back on if one set turns out to be unusable. GETTING STARTED Ready to start a backup? You'll need Quarterback and a box or two of floppy diskettes and labels. Load the Quarterback disk into one of your Amiga's disk drives. From Workbench: double-click the Quarterback icon. From CLI: type Quarterback. When the first screen appears, select either Backup to Floppies or Restrore from Floppies. From that point Quarterback leads you through the backup or restore steps, as described in the following sections of this manual. If you start Quarterback from CLI with no paramets, or from Workbench, it runs in a verbose interactive mode, prompting you for everything it needs to run. You can, however, run Quarterback from CLI with a command file, as described below. When started with a command file, Quarterback runs in a quiet mode, prompting you only for the diskette changes. To exit from Quarterback, select the QUIT item on the Project Menu, type Right-Amiga-Q, or click on the Close Window gadget. BACKING UP FILES TO FLOPPY DISK Start the backup process by clicking the Backup to Floppies gadget on the Quarterback copyright screen. Quarterback asks you to enter a valid device path for the files to be backed up. For more information, read the section "Selecting the AmigaDOS Device and Path" on page 8. When you have entered a valid device path, Quarterback builds a complete catalog of all files and subdirectories it finds there. For full backup of a heavily-used 20MB hard disk, this step may take as long as several minutes, during which time you should see the count of files changing as Quarterback bulds the catalog. Click the ABORT gadget if you can't wait for Quarterback to finish this step. When Quarterback has built the catalog of all files availabale for backup, it displays a portion of that list in a window so that you can decide which of the files (any or all) should be copied to floppy disk. Use the gadgets on the right side of the file window to scroll the file names up and down in the window. Use the gadgets on the elft side of the window to include or exclude groups of files, as described in the next section. When you have selected all the files you wish to back up, click on the PROCEED gadget. For more information, read the section "Including/Excluding Files in the Catalog" on page 9. SELECTING BACKUP OPTIONS Next, Quarterback displays various options which affect the backup process. Click on the appropriate gadget to indicate your choice. An orange background indicates "true" or "selected". Set Archive flag on backed-up files - When the backup is complete, Quarterback can set the archive bit for all files backed up. Files with the archive bit set can be skipped during subsequent backups. AmigaDOS clears the archive bit when a file is modified. note: This option increases the backup time a bit. Read diskette after write - If you want to be absolutely certain that your backup diskettes are readable, you should select this option, forcing Quarterback to perform a read check after every write. Note: this option increases backup time significantly. Overwrite AmigaDOS format on floppies - Quarterback totally destroys any old data on a diskette used for backups. This option directs Quarterback to overwrite each diskette with no checks for a valid AmigaDOS diskette. If you select "NO", Quarterback checks each diskette for AmigaDOS format, and warns you if it finds one. Print BACKUP report - This option directs Quarterback to send a report to your printer listing the files which it backed up. Beep for diskette change - This option directs Quarterback to beep when it is waiting for a diskette to be changed. Use floppy drive - This option lets you select which of your floppy drives you want Quarterback to use for the backup operation. If you specify BOTH, Quarterback automatically switches from drive to drive, as necessary, further reducing the backup time. Note: if you have only a single floppy drive, the DF1 and BOTH gadgets are disabled. When you have selected the options you prefer, you can start the backup operation by clicking the PROCEED gadget. Clicke the CANCEL gadget to abort the backup operation. Note: you can preserver your backup options in a parameter file, so that Quarterback can restore these options for your next backup. Read section "Saving Your Options" on page 10. DISKETTE MANAGEMENT DURING BACKUP At last we are ready to start the actual backup. Quarterback first displays its backup status screen, which shows the status of the backup operation and the ststus of DF0 and DF1. Quarterback displays messages in the DF0 and DF1 status boxes to prompt you for diskette changes. Whatch these boxes and the floppy drive lights to determine when to change floppy disks. WARNING -- Do not remove any diskette until Quarterback has turned off the drive light. If you do, the data on that diskette will be corrupted. The first data actually written to floppy is the catalog of files which are to be backup up to that set of diskettes. The catalog is always written to the first diskette of the backup set, where it can be easily found later for a restore operation. A Word to the Wise -- Label all diskette used for backup with the date and diskette number. Quarterback writes its own sequence number on each diskette, which is checked during the restore. Be sure you feed the diskettes to Quarterback in strict numberical order, matching the labels on the diskettes. Don't mix up the diskettes! You can abort the backup at any time by clicking on the STOP!! gadget. RESTORING FILES FROM FLOPPY DISK Let's hope you are reading this part of the manual out of curiosity, not necessity. But iof it is necessity, take a deep breath and calm yourself. A hard disk problem IS NOT the end of the world. It just seems that way right now. First collect your backup disks and the backup reports which go along with them. Which of the following scenarios best matches your situation? Restore Scenario 1 Your hard disk is fine, but you accidentally clobbered some files which you want to restore from the backup set. This is the simple case. Check your sets of backup disks to find the latest version of the file(s) you wish to restore. Then, just to be safe, consider restoring them into a different (new) directory on your hard disk. That way you can take a look at them before you move them into their proper directory. Restore Scenario 2 Something clobbered your hard disk's directory. You get a "validation error" from AmigaDOS. Your hard drive itself is probably not damamged (we hope), but you need to restore everything. This situation is annoying, but not a disaster. You must reformat your hard disk. Use the AmigaDOS Format program to rebuild the root directory. Follow the directions in the Amiga DOS User's Manual. The result will be an empty hard disk, ready for you to restore your files. If you have really trashed your hard disk the AmigaDOS Format program may not help. If Format fails to work or AmigaDOS still won't talk to your hard disk, you may need to perform a low-level format step. This requires a special format program which came with your hard disk drive. (Well it should have come with your hard disk drive!) The AmigaDOS Format program does not perform a low-level format for a hard disk. Refer to the drive manufacturer's formatting instructions, or contact the manufacturer before you attempt to reformat the disk. After performing a low-level format, you still must run the AmigaDOS Format program to initialize the directory structure, as described above. You can use the AmigaDOS LIST command to examine the hard disk's root directory. If you see "Directory is empty", then you are ready to proceed with a full restore from your backup disks. But don't start restoring files until you are sure your hard disk drive is working properly. Restore Scenario 3 Your hard disk drive died a horrible death, with great weeping and wailing. Now you own a new boat anchor. You have two choices. If you can get a replacement hard disk drive, install it, format it (if necessary, as described under Restore Scenario 2 above), and proceed with a full restore from your backup disks. The other choice is to restore some of your files to a different AmigaDOS device, such as RAM: or even a floppy disk drive. Obviously you cannot restore all of the files this way, but you can restore critical files. For a full restore, you must consider the backup scheme you have followed. If you have a full backup followed by incremental backups, you must restore the full backup first, followed by any incremental backups, in the order they were created. Start the restore process by clicking the Restore from Floppies gadget on the Quarterback copyright screen. Quarterback asks you to enter the device:path where the files are to be restored. For more information, read the section "Selecting the AmigaDOS Device and Path" on page 8. Enter the device:path for the files to be restored. Quarterback examines the device:path. If you specify a directory path which does not exist, Quarterback asks if you wish to create it. Next, Quarterback asks you to load the first disk of the backup set into disk drive DF0. Quarterback then reads the catalog of files stored ont he first diskette of that set, and displays a portion of that catalog in a window so that you can select the files to be restored to your hard disk. Use the gadgets on the right side of the file window to scroll the file names up and down in the window. When you have selected the files you wish to restore, click on the PROCEED gadget. For more information, read the section "Including/Excluding Files in the Catalog" on page 9. Click CANCEL if you decide not to restore the files. SELECTING RESTORE OPTIONS Next, Quarterback displays various options which affect the restore operation. Click on the appropriate gadget to indicate your choice. An orange background indicates "true" or "selected". Here are the restore options and their meaning: Restore only files which already exist - This option prevents Quarterback from restoring files to the hard disk which have been permantly deleted from teh drive (and you don't want to be restored). Quarterback first checks to see if the file still exists on the target disk. If not, Quarterback skips the file. Create subdirectories, as necessary - Use this option if you are restoring to a "virgin" hard disk or a different device:path which does not have the necessary directory structure already defined. If you select "NO", Quarterback skips any files which would have been restored to the missing subdirectory. Overwirte exisiting files - This option directs Quarterback to replace existing files, with no warning. If you select "NO", Quarterback asks before it replaces an existing file. Print restore report - This option directs Quarterback to send a report to your printer, listing the files which it restored. Beep for diskette change - This option directs Quarterback to beep when it is waiting for a diskette to be changed. Use floppy drive - This option lets you select which of your floppy drives you want Quarterback to use for the restore operation. If you specify BOTH, Quarterback automatically switches from drive to drive, as necessary, further reducing the restore time. Note: if you have only a single floppy drive, the DF1 and BOTH gadgets are disabled. When you have selected the options you prefer, you can start the restore operation by clicking the PROCEED GADGET. Click the CANCEL gadget to abort the restore operation. Note: you can preserve your restore options in a parameter file, so that for future restores Quarterback can set these options to your specification. Read section "Saving Your Options" on page 10. DISKETTE MANAGEMENT DURING RESTORE At lst we are ready to start the actual restore. Quarterback displays its restore status screen, which shows the status of the restore operation and the status of DF0 and DF1. During the restore process, Quarterback displays messages in the DF0 and DF1 status boxes to prompt you for diskette changes. Watch these boxes and the floppy drive lights to determine when to change floppy disks and which diskette to load. If you are using two floppy drives, Quarterback automatically switches disk drives as necessary, provided you keep up with the disk canges. Quarterback automatically senses whether or not you have changed diskettes. if Quarterback catches up with you, it will wait until you change the diskette. You must feed the diskettes to Quarterback in the order it requests them. Quarterback checks the sequence number on each diskette, and refuses to accept diskettes out of order. Don't mix up and skip some diskettes in the restore sequence. Don't be alarmed; this just saves time. You can abort the restore at any time by clicking on the STOP!! gadget. SELECTING THE AMIGADOS DEVICE AND PATH Quarterback must know the name of the AmigaDOS device you wish to backup from or restore to. This can be any valid AmigaDOS filestructured device. Quarterback initially assumes DH0:, but any properly mounted device can be used, incuding JH0:, RAM disks, recoverable RAM disks, local area networks, or even floppy disks. You can enter the volume name of the device in place of the device code. If you wish to back up all files from (or restore all files to) the entire device, enter only the name of the devide (and a colon), such as: DH0: Quarterback automatically includes files from the root directory and all subdirectories it finds on the device you specify. You can exclude some of these files from the backup, if you wish, before the backup actually begins. See the next section for details. If you wish to backup or restore only those files in a particular directory (drawer) or subdirectory, you should enter the complete path specification for the directory in which the files reside. Again, Quarterback automatically includes files from the specified directory as well as any subdirectories it finds in there. For example, to backup only those files found in the SYSTEM drawer of your hard disk, you would enter: DH0:SYSTEM You must enter a valid device for a backup or restore, and if you enter a path, the path you specify must already exist. This device:path tells Quarterback where to look for files to backup. If Quarterback cannot find the device:path you specify, it warns you and waits for you to correct the entry. For a restore, you ned not specify the same device:path that the files came from when you made the backup. In fact, you may want to restore your files to a different device or directory so that you can examine them before moving them to their proper directory. Or if your hard disk has failed, you may not be able to restore your files to the same device. However, the device:path you enter must already exist. INCLUDING/EXCLUDING FILES IN THE CATALOG Quarterback automatically builds and displays a catalog of files available for backup or restore. For a backup, the catalog is built from files found in the device:path you specified. For a restore, the catalog is read from the first diskette of the set to be restored. The catalog lists all files available to be backed up or restored. However, you may wish to backup or restore only certain of the files in this catalog. This section describes the commands Quarterback parovides to include or exclude files from the operation. The catalog groups files by directory or subdirectory. At any instant you can examine only the files and subdirectories defined for the directory whose full path is displayed just above the file windeow. Use the scrolling gadgets on the right side of the window to move through the list, if there are more names than can fit in the window. If you click on a subdirectory name in the window, Quarterback displays the files (and subdirectories) of that subdirectory. Use the PARENT gadget to move back to the previous directory. By clicking on subdirectory names, you can quickly move down to the lowest levels of a directory tree to examine all files available to process. Use the ROOT gadget to return instantly to the top level of the structure. note: the term "ROOT", as used here, means the highest level directory, as defined by the device:path. If you have defined a device only, such as DH0:, then ROOT implies the root directory of DH0. If you have defined a complete directory path with your device, as in DH0:SYSTEM, then ROOT implies that specific directory on DH0:. Initially ,all files in the catalog are marked as "included". This means that if you want to backup or restore all files, you can immediately click on the PROCEED gadget. If you wish to exclude a particular file from the process, click on its name in the window. Click on its name again to include it again. In this manner, you can include or exclude individual files, as you wish. Quarterback displays the files and any subdirectories of the catalog in alphabetical order, with subdirectories listed first. Files included for backup or restore are displayed in black letters on an orange background. Files excluded for backup or restore are displayed in white letters on a black background. Subdirectory names are displayed in orange on a black background. note: These colors depend upon your Preference settings. The colors described here represnet the standard Preference colors of AmigaDOS V1.2. A legend at the top of the window indicates the colors that apply in your case. Quarterback displays a status line near the top of the screen showing the number of files currently included, the total number of files in the catalog, the total size in bytes of the included files, and the number of diskettes required. if you wish to include or exclude groups of files, you can click on the "include" or "exclude" command gadgets along the left side of the file window. These commands apply either to the current directory only or to the current directory and all subdirectories. Click on the desired gadget to change this mode. Each command performs only the action specified. This means that "inclusion" of a particular group never implies "exclusion" of any other files. INCLUDE/EXCLUDE ALL - These gadgets include all files or exclude all files. Use the EXCLUDE ALL gadget to exclude all files quickly, so that you can then include certain files or groups of files for backup or restore. INCLUDE/EXCLUDE BY NAME - These gadgets trigger a request from Quarterback for the name of the file(s) to include or exclude. You can use wild cards here to include or exclude particular groups of files by name. Use the standard Amiga wild card characters "?" to specify any single character, and "#?" for any number of characters in the file name. Example: #?.doc This will include or exclude all files ending in ".doc". INCLUDE/EXCLUDE BY DATE - These gadgets let you include or exclude files based on their file date. These gadgets trigger a request from Quarterback for the cut-off date you wish to use. The INCLUDE BY DATE gadget includes only those files which have file dates equal to or later than the specified date. The EXCLUDE BY DATE gadget excludes only those files which ave a file date earlier than the specified date. INCLUDE/EXCLUDE ARCHIVE - These gadgets let you include or exclude files according to the stat of the file's archive bit. AmigaDOS CLEARS the archive bit on a file when a program changes the file. Quarterback can be instructed to SEET the archive bit for any file it backs up to floppy disk. Then if a file is changed before the next backup, Quarterback knows that the file should be backed up again. Files which have not changed since the last backup will still have the archive bit set, and can be ignored for this backup. Click the INCLUDE ARCHIVE gadget to include all files whose archive bit is CLEAR (file changed). Click the EXCLUDE ARCHIVE gadget to exclude all files whose archive bit is SET (file unchanged). Example: To include only those files which have changed since the last backup, click on EXCLUDE ALL, and then on INCLUDE ARCHIVE. SAVING YOUR OPTIONS When you have specified the various Quarterback options which you prefer to use, you can save these options in a parameter file. Quarterback restores these options (if it can find the options file) for subsequent backup/restore operations. To save these options for future use, select SAVE OPT from the Project menu, or type Right-Amiga-S. The parameter file, named QB.OPT, is saved in the S: directory. BACKUP/RESTORE REPORT When Quarterback performs a backup or restore process, it prints an optional report listing all files processed, the date of the activity, and the device:path. We recommend that you keep the backup report with the set of diskettes produced by the backup. Caution: for a full backup/restore, this report can become very lengthy. USING COMMAND FILES If you are familiar with the Amiga CLI interface, and if you wish to make frequent backups of selected subdirectories, you may wish to invoke Quarterback with a command file containing lists of files to backup. In this mode Quarterback takes its commands from the file, loads your options from the parameter file, and automatically begins the backup. All you have to do is change the diskettes. To invoke Quarterback from the CLI with a command file, type the following: Quarterback WITH file where 'file' is the name of the file you have prepared containing Quarterback commands. The Quarterback command file is an ASCII text file, prepared using any standard text editor, such as ED or TxED. The basic syntax is: BACKUP device:path [options] RESTORE device:path [options] The device:path must be a valid AmigaDOS device with optional directory path. The directory path must already exist, if specified. The options are keyword parameters in any order, defined as follows: ARCHIVE Include only files with the archive bit clear. DATE dd-mmm-yy Include only files changed on or after that date. INCLUDE file(s) Include this file. Wild cards are permitted. EXCLUED file(s) Exclude this file. Wild cards are permitted. INCLUDEALL Include all files. EXCLUDEALL Exclude all files. For example, let's assume you command file is called BACKUP_DOCS, and contains: BACKUP DHO:WP/DOC EXCLUDEALL ARCHIVE INCLUDE #?.DOC If you type: Quarterback with BACKUP_DOCS Quarterback will backup to floppy all document files which ahve been modified since the last backup having any name ending in ".DOC" in subdirectory WP/DOC on hard disk DH0:. ACCESSING AmigaDOS You can open a new CLI window from within Quarterback. Select the New CLI option in the Project Menu. You can then perform other operations while Quarterback is running. Note: For this function to work, you must have bothe the "NewCLI" and "RUN" programs in your C: directory. AMIGA 2000 USAGE Quarterback can backup files from any standard AmigaDOS device, including an Amiga partition on a hard disk drive attached as an MS-DOX peripheral on the Amiga 2000. This device is normally defined as JH0:. Note, however, that Quartervack cannot directly access files on the MS-DOS partition of that disk drive. Therefore, you cannot use Quarterback to backup the MS-DOS files on an A2000. PROBLEMS? Here are some potential problems which you may encounter, and possible solutions. Insufficient memory - Quarterback itself is small, but it needs lots of memory to build its catalog of files, and it need buffer space in "chip" memory. If you experience memory problems, you may need to stop other programs, especially memory-resident utility programs. Backup disk errors during restore - If you experience disk errors during a restore, Quarterback lists the file(s) which cannot be recovered. These files are written to the hard disk, but may contain garbage. Locked files during restore - Files which are locked by another program cannot be restored by Quarterback. if necessary, terminate other programs which may be interfering. You may have to reboot your Amiga to free files which were left locked by another program. TECHNICAL INFORMATION Quarterback performs a file-by-file backup. It does not save an image of the hard disk. This means that the backup time depends solely upon the number and size of the files to be backed up. It also means that when files are restored to a freshly-formatted hard disk, the files are stored with less fragmentation, resulting in faster access times. The diskettes written by Quarterback are not compatible with AmigaDos. Therefore you must use Quarterback to find and restore the files from a set of backup diskettes. Remember to keep a copy of Quarterback on a floppy disk so that you can restore your files if your hard disk drive fails. ============================================================================= Quarterback docs brought to you by The Southern Star.
