Full Backup To back up a directory or folder, click on 'Full Backup' under the 'File' menu. You will be shown three dialog boxes in turn. Select the files to back up from the SELECT FILES box and click on OK. Select the backup set name and output folder name from the OUTPUT PARAMETERS box and click on OK. Select the floppy disk parameters from the INSERT FLOPPY DISK box and click on OK. Change disks only when instructed. See separate help items for use of these dialog boxes. Daily Incremental Backup To back up only those files in a directory or folder that have changed since the last backup, click on 'Daily Incremental Backup' under the 'File' menu. You will be shown either three or two dialog boxes in turn, depending on whether this is the first incremental backup since the last full backup. Select the files to back up from the SELECT FILES box and click on OK. If you are shown the OUTPUT PARAMETERS box, select the backup set name and click on OK. Select the floppy disk parameters from the INSERT FLOPPY DISK box and click on OK. Change disks only when instructed. See separate help items for use of these dialog boxes. Cleanup Incremental Backup To back up only those files in a directory or folder that have changed since the last full backup, click on 'Cleanup Incremental Backup' under the 'File' menu. You will be shown three dialog boxes in turn. Select the files to back up from the SELECT FILES box and click on OK. Select the backup set name from the OUTPUT PARAMETERS box and click on OK. Select the floppy disk parameters from the INSERT FLOPPY DISK box and click on OK. Change disks only when instructed. See separate help items for use of these dialog boxes. Archive Bit TOS version 1.4 or newer will set the "archive" bit on a file whenever it is modified. This includes modifying a file with a database and any time a file is created. A file which is moved by copying and then deleting the old file will have its archive bit set, too. Normally, The Vault does not back up according to how the archive bit is set, but does clear the bit when it backs up a file. When the "Use Archive Bit" flag in the "Options" menu is set, The Vault will back up files with the archive bit set and new files when doing an incremental backup. If a file it backs up would not have been backed up without the "Use Archive Bit" flag, The Vault also changes its date so it would have been. This way, it will be backed up on subsequend Cleanup Incrementals. Note that this option is not available with TOS 1.0 or TOS 1.2 Full Copy Full Copy is like Full Backup except that no log file is written, files are never split, and no disk label checking is done. It is useful when you just want to copy data, such as making up disks for a user group or a friend. To use, click on 'Full Copy' under the 'File' menu. You will be shown three dialog boxes in turn. Select the files to back up from the SELECT FILES box and click on OK. Select the backup set name and output folder name from the OUTPUT PARAMETERS box and click on OK. Select the floppy disk parameters from the INSERT FLOPPY DISK box and click on OK. Change disks only when instructed. Note that you will not be asked for a backup set name and the line for specifying the output folder is much longer than for a full backup, allowing you to type a full path name. See separate help items for use of these dialog boxes. Incremental Copy Incremental Copy is like Full Copy except that only those files created or modified since a date and time you specify will be copied. To use, click on 'Incremental Copy' under the 'File' menu. You will be shown four dialog boxes in turn. Select the files to back up from the SELECT FILES box and click on OK. Select the output folder name from the OUTPUT PARAMETERS box and click on OK. Select the cutoff date from the EARLIEST DATE box and click on OK. Select the floppy disk parameters from the INSERT FLOPPY DISK box and click on OK. Change disks only when instructed. Note that you will not be asked for a backup set name and the line for specifying the output folder is much longer than for a full backup, allowing you to type a full path name. See separate help items for use of these dialog boxes. Select Files Dialog Box The SELECT FILES dialog box allows you to specify which files you want copied. It has three parts: the pathname of the directory to back up, the directory selection masks, and the file selection mask. The file selection masks allow you to select only certain files for backup. (See 'File selection masks' in the Help menu.) First, all folders in the starting directory are backed up, unless something other than '.' is used as the directory selection mask. (See 'Directory Selectin masks' in the Help menu.) All files in the selected folders that match the file selection masks are then copied. Specify the pathname and wildcard filter using the mouse or keyboard. To use the mouse to select a pathname click on the 'Use File Selector Box'. When using the file selector, only the directory line matters; the selection line is ignored. File Selection Masks File selection masks let you select which files to back up. Use *.* to include all files. '*' matches any string of zero or more characters, '?' matches exactly one character, and other characters match themselves. Thus, *.PAS would match only those files whose type is '.PAS', and *2.? would match all files whose name ends with '2' and whose type is a single character. If you give more than one mask, The Vault uses them from left to right. For example, *.pas *.c backs up all the '.PAS' and '.C' files. A mask preceded by an exclamation point (!) excludes the matching files. For example, *.* !*.BAK backs up all files except the '.BAK' files. Each new mask adds to or subtracts from the set of files specified by all preceding masks. For example, *.* !TEST.* *.C starts with all files, then removes those matching 'TEST.*', then adds back all files matching '*.C'. Note that 'TEST.C' will be backed up by these rules. Directory Selection Masks Directory selection masks let you select which folders to back up. Use '.' to include all subdirectories of the starting directory. Unlike File Selection Masks, wildcard directory names are not allowed. Each Directory Selection Mask is simply the "tail-end" of a path-name. If the starting directory were E:\R\ and you wanted E:\R\DOCS\ and E:\R\RECIPES\ to be backed up, then the DOCS\ and RECIPES\ would be the correct masks to do that. As with File Selection masks, if you give more than one mask, The Vault uses them from left to right. A mask preceded by an exclamation point (!) excludes the matching folder. A mask preceded by a '#' (not excluding the possibility of a '!') will tell the Vault that the mask does not apply to the subfolders. So, '#.' means backup the starting folder and none of its subfolders. '. #!X\' means back up all folders, except folder X\, but do back up the subfolders of X\. Output Parameters Dialog Box The OUTPUT PARAMETERS dialog box lets you select the output folder and the backup set name and starting volume number. Enter the requested information from the keyboard. The output folder should be at most eight characters and may contain only letters and digits when doing a backup, but it can contain any legal path name characters when doing a copy. The backup set name should likewise consist of at most eight alphanumeric characters. The starting volume number should generally be 1. Insert Floppy Disk Dialog Box The INSERT FLOPPY DISK box asks you to insert a disk and specify which drive the disk is in and how it should be treated. Click on the box corresponding to the drive you are using. If dual mode is selected, when The Vault is finished writing a disk, it will look in the other drive and if the disk it expects is there, The Vault will write it. This allows for continuous writing for two-drive owners. You have three options of what to do to the disk: You can either format it, clear it, or append to it. The Vault normally selects the proper option by default, but you can override its selection when necessary by clicking on the appropriate box. The append option is intended for daily incremental backups and only works quickly on disks which were written by The Vault or which have no fragmented freespace. Formatting a Floppy If you select the 'format' option from the INSERT FLOPPY DISK box, a FORMAT box will appear asking you to specify how you want your disk formatted and giving you the opportunity to change your mind. The FORMAT box will also appear if The Vault decides that the disk needs formatting. The FORMAT box lets you select whether to format single or double sided and 9 or 10 sectors per track. "Standard" is 9, but using 10 sectors per track reduces the size of the backup set. You are also given the option of specifying the serial number on the disk. All disks _must_ have a unique serial number. If you don't have a system for making up your own serial numbers, make sure that 'Random Serial Number' is checked and The Vault will choose one for you. Otherwise, uncheck it and type in the serial number in HEX (base 16). The Backup Set Name A backup set is a set of floppies which were all created during the same backup operation. Each backup set has a name attached to it, called a "set name", which consists of any alphanumeric string up to eight characters long. You are asked to enter the backup set name when you select 'Full Backup' from the 'File' menu. The set name should be different for each different full and incremental backup set. Each diskette in a backup set is assigned a volume number, starting with the one you enter (normally 1). Thus, each backup disk is uniquely identified by its set name and volume number. The WRONG DISK INSERTED box will appear if the disk's set name and number do not match what was expected. Wrong Disk Inserted Dialog Box When you are asked to insert a disk, The Vault checks the name and number of the disk you insert to make sure it's the correct one. If it isn't, you have there options: 'Switch disks' goes back to the INSERT FLOPPY DISK box and lets you try again. 'Relabel & Proceed' writes the expected label on the disk and then proceeds normally. 'Proceed' goes ahead and uses the disk that was inserted. It also changes the expected backup set name and volume number to match what was on the disk, so the next disk requested will be the next one in sequence in the new backup set. Write Verify Option Normally, the Atari ST verifies everything that it writes to disk, ensuring that all data written will be readable. You can turn this off and speed up the backup process considerably by unchecking the 'Verify Writes' menu item. If you do, you are increasing the chance that you will find your backup data unreadable when you need it. Split Threshold The 'Split Threshold' allows you to control when files are split across more than one floppy disk. Files shorter than the split threshold will never be split, and the amount of wasted space on a floppy (except for the last) will never be larger than the split threshold. Thus, the larger 'split threshold' is, the fewer files will be split but the more wasted space there might be on each floppy. Because The Vault uses a sophisticated file packing algorithm, the amount of wasted space on each disk is generally much smaller than this parameter. We recommend a value around 40% of the capacity of the floppy disks you are using. The threshold must always be less than the total disk capacity. To change this number, click on the 'Set Split Threshold' menu item under OPTIONS. Make sure that you set it to something smaller than the smallest disk you will be using. Otherwise, a file larger than that disk may confuse The Vault. Save Defaults Option You may save the default options so they will be the same every time you run The Vault. To do this, select 'Save Defaults' under the 'Options' menu. All of choices that you made in all of the dialog boxes and menus will be saved in a file called VAULT.INF which is written in the directory from which you ran The Vault. History File Whenever you back up the disk, a history file is created in the folder you backed up, called '_BACKUP.HST'. The history file contains the names of all files backed up and the name of the disk on which they are stored. This provides a convenient means of locating a specific file in the backup set. The first four lines of the history file contain the date and time of the last incremental and full backups, the last output folder used, and the last incremental disk used. Another file, called '_BACKUP.CTL' is created which contains only the header information from '_BACKUP.HST'. The first four lines of this file are used to control incremental backups and should not be changed. It is OK to change or delete the rest of the file.
