We are currently running Veritas NetBackup 6.0 (with no maintenance packs) on one Master/Media/EMM server for our one-site-office. Recently we have been experiencing issues restoring from several Ad-Hoc backups. The Ad-Hoc policy details are:
6.0 with no maintenance packs is suicide. I very strongly suggest you upgrade. Your backups are at risk.
Type: Full Backup
Retention: Infinity (Level 9)
Backups are not archives. But if you insist...
We use this for archiving information as and when we need to perform an archive. However, when we goto the restore utility some of the backup jobs are in the NetBackup History but others are not. Previously we used the retention "1 year" (Level 8) so some of the older backup tapes (including the tapes we are attempting to restore from) have this retention. Could this be an issue?
Absolutely. If the image is written with a 1 year retention, then when the image expires, its contents in the catalog are erased. If all the images on a tape have expired, then the tape is put back in the scratch pool.
If so, how do we change the retention level of a tape? We have tried changing the retention of the policy back to Level 8 to no avail.
You change the expiration of the image, not the tape. Use bpexpdate to do this.
If you want until the image expires, it could be too late - the tape could already be overwritten. You *must* change the expiration *before* the image expires. Once the image has been written, the policy is no longer relevant - you can delete the policy and the data will still be there until the image expires.
