OK so I think this is one of the culprits for the issue I'm having right now:
When Veeam Backup & Replication executes a GFS job, it performs the following operations:
At 00:00 of the day set in the GFS job schedule the GFS job starts and checks periodically if the source job created a backup:
- If the source job creates a full backup, the GFS job copies it.
- If the source job creates an incremental backup, the GFS job synthesizes a virtual full backup.
- If no backup appears in 24 hours, the GFS job looks for the most recent restore point available. If it is a full backup, the GFS job copies it. If it is an increment, the GFS job uses it to synthesize a virtual full backup.
Specifically the second item on that list. Seems like I either need to move to reverse incrementals or run a full backup prior to the the tape job. Any recommendations? The full backups size for each datastore is 3.3 TB, 5.26 TB, and 4.65 TB respectively.
