I have a Sybase IQ 12.4.2 DB on a WIN2K server. We perform all of our db backups directly to SDLT tapes using something along the lines of:
BACKUP DATABASE FULL TO '\\.\tape0' SIZE 110000000 WITH COMMENT 'FUll DB Backup'
This is called from a perl script and has been working fine for the last 12months. Recently we applied Win2K service pack 2 and the blaster patch, now I get the following error when trying to backup to tape.
General error: Error during backup: unsupported blocksize on \\.\tape0 (SQL-HY000)
Does anyone have any ideas as to what has caused my backups to start failing, and/or how to fix it or get around the problem??
