Hello all,
We have a typical Hyper-V environment with about 50 VMs. We're performing full backups daily.. For offsite copies, we use a GFS (Grandfather-Father-Son) backup setup with a tape library with daily/weekly and monthly/yearly retention policies.
Everything runs fine overall—we just need to manually delete daily tapes after a week due to retention issues with big data apps not syncing correctly with the planned retention schedule. This is manageable on our end.
The real issue is with restores. We have a backup site that is fully offline and is a clone of the primary site. When we try to restore VMs, most restore fine and grab the index from the daily tape. However, some VMs require indexes from other tapes. To restore all VMs, we often need 2–3 additional tapes from within the 7-day window. In other words, not all indexes are stored on a single tape—this is evident from the index size per tape.
It seems the problem is related to the IndexCheckpoint and how the index database is written every 7 days. Since we’re performing full backups daily, it appears the system skips creating a new checkpoint or consolidated index, which might be causing this issue.
Commvault Support hasn’t been able to understand the problem so far. Has anyone else experienced something similar?
is there a way to force more frequent index checkpoints ?
