- Compatibility Statement
- Sytron Corporation's Sytos Plus for DOS v1.32 is compatible with
- LANtastic NOS version 4.xx.
-
- Product Overview
-
- Sytos Plus is a file backup manager designed to operate with a
- variety of backup storage devices, including floppy diskette,
- quarter-inch tape, data cassette, etc. It allows you to set up
- backup procedures to be run automatically at specified times. It
- also supports password protection of media, quick file access
- during restore, and customizable log to record status of unattended
- backup procedures. Users are strongly recommended to read Chapter
- 2 "Backup Strategies" in their User's Guide to design and implement
- an efficient backup strategy to protect their important data.
-
- Product Installation Notes
-
- Sytos Plus can be installed on the network server or the
- workstations, but it can only be run from the node to which the
- backup device is attached. Be sure the backup device settings (e.g.
- DMA channels) are not used by the network adapter card or other
- devices in your system.
-
- The Sytos Plus Scheduler (SYPLUS /I) permits backup procedures to
- be executed at pre-designated times. It exists in the form of a
- TSR. It uses about 2K of RAM, and can be loaded high by the MS-DOS
- 5.0's loadhigh command.
-
- The "Network Environments" section in their "Getting Started Under
- DOS" booklet contains a lot of useful information about using Sytos
- Plus on a DOS network, including how to handle redirected drives
- and the need to obtain access privileges to read a file. Basically,
- if drive mappings changed after files are backed up, the files will
- be restored to the original drive or may not be restored if that
- drive is no longer valid. In this situation, you can use the Sytos
- Plus Redirection option during the Restore to reference a new drive
- letter.
-
- Product Execution Notes
-
- If a file is opened by another user when Sytos Plus attempts to
- back it up, Sytos Plus will place the file in a "Busy" file log.
- Sytos Plus can also optionally retry this file at the end of the
- backup procedure. The retry interval (time between retries) and
- length of time Sytos Plus will wait to retry busy files are user
- configurable. Similarly, when restoring files, make sure that users
- are not using files in the directory you want to restore, since
- files that are open ("busy") cannot be overwritten.
- Some administrative tips for the LANtastic environment:
-
- 1. To shutdown a server to prepare it for backup, try
- NET SHUTDOWN \\<servername> 10 "Shutting down in 10 minutes"
-
- This schedule the shutdown in 10 minutes and send a warning
- message to all users logged into the server.
-
- 2. To find out who has logged onto a server, use the Monitor and
- Manage Server Activity Option from the net utility.
-
- 3. A new net command called SLOGINS is added to LANtastic NOS
- v4.1, which can enable or disable user logins to a server. The
- syntax is: NET SLOGINS(/ENABLE /DISABLE) \\<servername>
-
- 4. You can use either of 2 backup and restore methods to ensure
- complete recovery of a LANtastic network:
-
- a. using the NET_MGR utility to backup the LANtastic network
- control directory, and then Sytos Plus to backup the rest
- of the files.
-
- b. using only Sytos Plus to backup all files.
-
- Please refer to the attached Product Support Tip No. 8 from
- Sytron on the details of each method.
-
- 5. The NET_MGR utility also provides a command line interface for
- advanced users. Here are a few of those for your reference.
- Details of the commands can be found in appendix C "NET_MGR
- Commands and Switches" of the LANtastic v4.1 Upgrade Manual.
-
- To backup a server's control directory to a specified file:
- NET_MGR BACKUP <control-directory-path> <target-file>
-
- To restore a control directory that has been backed up:
- NET_MGR RESTORE <backup-file> <control-directory-path>
-
- 6. The DOS filesystem stores the date and time when a file was
- last updated (created or modified). You can implement an
- incremental backup strategy based on this date.
-
- Printing
-
- Sytos Plus defaults to print the backup log to PRN. You can use the
- LANtastic net utility to print to a remote printer on your network.

- Sytos Plus for DOS 1.3 under LANtastic v4.0 and 4.1
- Summary
-
- To be able to recover the complete LANtastic network, the LANtastic
- network control directory, \LANTASTI.NET, must be backed up and
- restored. The directory LANTASTI.NET contains the hidden
- subdirectories \LANTASTI.NET\SPOOL.NET and
- \LANTASTI.NET\SYSTEM.NET.
-
- You can use either of two backup and restore methods to ensure
- complete recovery of a LANtastic network:
-
- o Method 1: using the LANtastic NET_MGR utility and Sytos Plus
-
- o Method 2: using only Sytos Plus
-
- Using the NET_MGR utility involves more steps. Using only Sytos
- Plus requires less steps, but non-existent hidden directories are
- restored with the hidden attribute.
-
- Method 1: Recovery of a LANtastic Network using NET_MGR
-
- This recovery method consists of two major tasks:
-
- A. Backing Up the Network
-
- B. Restoring the Network
-
- Steps to Backing up the Network can also be found in the LANtastic
- reference Manual in the chapter Control Directory Maintenance.
-
- A. Backing Up the Network
-
- 1. Shut down the server using the NET SHUTDOWN \\SERVERNAME
- command.
-
- 2. Enter the LANtastic NET_MGR utility
-
- 3. At the Control Directory Maintenance menu, back up the Control
- Directory by choosing Change Directory and then the Backup
- Control Directory Option.
-
- 4. Enter Sytos Plus and exclude the network control directory
- from the Backup Procedure. To exclude the network control
- directory:
-
- a. Enter Source Files... from the Sytos Plus Main screen.
-
- b. Choose <F8>=Selection Sheet
-
- c. From the Selection Sheet window choose <INS>
-
- d. Type the directory you wish to exclude:
- <drivename>:\LANTASTI.NET\*
-
- e. At the Exclude button, press the space bar to exclude
- these files.
-
- f. At the Directory button, press the space bar to exclude
- subdirectories.
-
- 5. Run the Backup Procedure.
-
- B. Restoring the Network
-
- 1. Run a full system Restore using Sytos Plus. (Refer to the
- Sytos Plus User's guide for details)
-
- 2. Run a full system Compare Procedure.
-
- 3. Enter the LANtastic NET_MGR utility and restore the Control
- directory by choosing the Restore Control Directory option.
-
- Method 2: Recovery of a LANtastic Network using Sytos Plus
-
- Sytos Plus automatically backs up hidden subdirectories under DOS.
-
- NOTE: If the hidden directories being restored do not exist, Sytos
- Plus restores them but without their hidden attributes.
-
- To recover a LANtastic network, use the Backup and restore steps
- detailed in the Sytos Plus User's Guide, and follow these
- guidelines:
-
- o Prior to running a Backup, shut down the server using the NET
- SHUTDOWN \\SERVERNAME command. This ensures that all critical
- network files are accessible during the Backup Procedure.
-
- o After completing the Restore Procedure, run a full system
- Compare Procedure.
