Changing Retention levels on Tape
Hi.
We are using Symantec Netbackup 7.5 on Redhat Linux with standalone tape drive . I have created backup policies with retention level= 2 months, and all backup's have been successfully completed on allocated tape A0005.
Now, I have to change the retention levels of all backup policy to 1 year, is there any way that I can use the same tape(A0005). Currently the backup fails when I change the retention level, it's asking for new tape .
Can I manually expire the old images on the tape and delete it.
Thank You
Hi,
Please review the note on changing retention levels if you've not done so already https://www.veritas.com/support/en_US/article.000085901
Your backups are probably failing after you change the retention because your environment is set to not mix allow different retentions on a single media. You can update this on the host properties > media tab.
You'll then be able to backup multiple retentions on to one tape. Please take note though that a media will not become available if a backup with a retention is still unexpired on it.
