Earlier we used:
- Forever Incremental backup, once a week the tape job made a "virtual Full Backup".
The problem was, that the tape job was cancelled once a normal backup job started. As tape jobs take a long time, this happened quite often.
We changed to:
- Incremental backups with weekly Active Full Backups (Took twice as disc space). The Tape job didn't have troubles anymore.
From support I got told, the reason is, that files get locked and the tape has to cancel the job.
Now I would like to know if this behavior changed with REFS and we could switch back to forever incremental.
As if I understand correct, the "virtual Full Backup" only links to blocks from the initial full backup, and wouldn't lock anything.
Can you confirm, as we would like to move to REFS to have less disk usage and decrease the active full counts.
Also, is there a best practices yet for REFS, other than using 64K?
