Backup Exec 2014 Backup-to-Dedupe Duplicate-to-Tape
Some other questions have touched on this topic but they all seem to be just a little different than my scenario. The issue I seem to be having is the following.
I have a single Windows Server 2008 R2 server with Backup Exec 2014. I am not using CASO with a MMS. I run incrementals throughout the week and then a full backup to our dedupe storage on a SAN. I then run a duplicate of the previous Full backup job (not using scheduled option for duplicate job) to duplicate to tape for off-site storage. The intention is to retain two weeks of data on-site and more off-site. However, I see instances where, if the duplicate to tape job failes, the previous Full backup is no longer on the dedupe storage. This means we have to do the entire full backup over again and then duplicate to tape.
In addition, this concerns me because I wonder if all the other jobs we write to tape in this manner are also getting removed from dedupe storage after the job either completes successfully or fails. It concerns me because we want to retain some of those on-site.
Is this by design? Is there a way around this?
