I am running Veritas 9.1 on Windows 2000 Server using a Dell Power Vault 122T robotic library that hold 8 tapes with 1 internal tape drive.
I have my backups set to run differential Mon-Thurs., and Full backup on Fri. using 2 tapes. I want to rotate tapes by day and am using 12 tapes for a 2 week rotation. I have jobs, media groups and media set up by Day/Week (Monday Week 1, Friday Week 1 Tape 2, etc.).
Not always, but at least once a week, and sometimes more, Veritas will grab the media from a different media group and use that instead of the asigned media, even though there should be room on the assigned media, and the rules as far as I can tell should allow it be overwritten if there not enough room to append. I have examined the logs and all the settings and I can see no reason for this, nor can I find anyway to force Veritas to use the media I assign for the job.
This creates havoc for my tape rotation, and last night (Weds.) it overwrote Tape 2 from my Friday Full backup of 2 weeks ago. This is driving me crazy, and doesn't make me feel secure about our backups or backup stratagy. Please help!
Thanks in advance!
