Our Compaq server has a 24GB backup tape drive which saves backups and gets data from backup tapes fine normally. However we are finding that we are having to run the DAT3 Cleaning tapes before we do every single backup otherwise we get a "Unrecognisable Data" error come up in the backup log after a few files.
If we backup then clean, then backup again its fine. But if we backup then clean, then restore some data from tape, and THEN try to backup, et voila the problem occurs.
Anyone know if this is something we can easily fix or do we need a new tape drive ???
We've tried different, including brand new, cleaning tapes but they have no effect. Just regular cleaning before doing a backup works.
