- LANtastic NOS 4.0 Technical Bulletin:
- Tecmar Tape Drives and QT Quality Tape Backup Software v1.2x
- 9/12/91 JAG
-
-
- I. Overview
- The QT tape backup software from Tecmar, Inc was tested using the Tecmar
- QT-250es External 250MB SCSI tape drive and an Adaptec SCSI interface adapter.
- Since the software interacts directly with the tape drive hardware, each
- computer on the LAN which will be backed up must be configured as a server.
- The general procedure is for the machine with the tape drive attached to login
- to each server and backup the server's files to the local tape drive.
-
-
- II. Installation
- Follow the manufacturer's instructions for installing the tape drive hardware
- and software. The tape backup machine may be configured as a LANtastic
- workstation or server, depending on the user's preference. Once the drive and
- software are installed, you must configure them for the LAN. To do this, change
- to the QT directory and bring up the software. Select the "Change Setup
- Options" (F5) option and press F1 for the "Change Configuration Values" section.
- Choose the "Network type" parameter and set it to "Other." Then select the
- "Swapfile drive" option and set it to a local (attached to he tape drive
- machine) hard disk drive. Press ESC and answer 'Y' to the "Keep these values?"
- prompt.
-
-
- III. Program Execution
- The QT software can be run in menu, command line, or automatic backup modes.
- All modes can be used with LANtastic. Note that the menu mode requires a
- minimum of 512K base RAM to run. All backups should be done as file-by-file
- backups, image backups are not possible on network drives. Drives on servers
- that are to be backed up must be NET USEd before running the backup software. If
- the backup is configured to wait for open files to close before backing them up,
- it is recommended that the network control directory (\LANTASTI.NET by default)
- on each server be excluded from the backup. See the QT Software documentation
- for information on excluding directories from the backup. If the backup is
- configured to skip open files, it is not necessary to exclude the servers'
- network control directories.

- IV. Compatibility Notes
- The QT Software v1.2x is currently incompatible with the LANtastic LANCache
- program. If LANCache is normally used on the machine to which the Tecmar drive
- is attached, it must be removed from memory before starting QT. This can be
- done by running LANCache with the /remove switch from the DOS command line or
- by rebooting the computer and bringing it back up without LANCache installed.
- This bulletin will be updated once compatibility problems are resolved.
-
-
- V. Conclusion
- Tecmar, Inc.'s QT Software v1.2x is compatible with LANtastic NOS v4.0 with the
- exception of the above Compatibility Note.
