I have Backup Exec 2012 SP3 running on Windows Server 2008 R2 backing up a few VMs from an ESXi host on a D2D2T backup plan with weekly full and daily incremental backups to deduplication store, linked copy jobs to a LTO tape library, and a monthly copy job of the last full tape backup to a standalone drive for off-site storage.
Last week I modified that job, removing one of the VMs. Today I find the monthly off-site copy has five times the size of the last weekly full it should be a copy of, and consequently did not fit onto the intended tape. Looking in the job log I see it has copied the last four full backups instead of just the last one as I requested.
What might have caused that misbehaviour and how can I avoid that in the future?
Thanks,
Tilman
