- If you are backing up Exchange server and the System State on Windows 2003, we recommend setting up one job to backup Exchange Server to a file, and then backing the rest of your system in a second job. Schedule the first job to run several hours before your second job. This way, you will have backups of both Exchange and your System State, and work around the problem of appending to tape.

On Windows XP and 2003 Server, the Travan tapes in the STT3401A? drive may be detected as MiniQIC? instead of Travan. Explanation: A bug exists in the Windows driver for this tape drive where the tape in the drive is detected as the wrong format Resolution: In the Media Pool setting in the Options tab of BackupAssist, select MiniQIC? instead of Travan.September 20, 2004, at 05:31 AM

Notes on Travan tape drives
Added lines 7-16:
- Advantages:
- the tape drive units are comparatively cheap
- IDE models of Travan drives are available and are easier to setup than SCSI drives
- Disadvantages:
- blank tapes are expensive
- the tape drive unit is noisy and slow
- tapes require periodic retensioning
- most Travan drives do not have hardware compression

to:
The Phase Two backup is performed as an append operation to the end of the tape (after the Phase One backup has completed.)
Resolution: There are two ways of working around this error:
- Purchase a more reliable tape drive, such as a DDS tape drive
- Turn off the Phase Two backup by disabling the backup of Exchange Server, SQL Server and Open Files. (To turn off the open file backup, go to the Options Tab of your backup job.)

We believe that the Windows drivers for Travan drives are buggy. We are now recommending against using Travan tape drives because of the large number of problems that our users are having with this particular type of hardware.
