Snapshot and transaction log (TLOG) considerations
For stable backup and recovery behavior, follow these general guidelines:
Perform a full backup at least once a week.
Perform incremental backups at least once a day.
Once a full backup is started, earlier backups cannot be used as the source for subsequent incremental backups, even if the full backup fails.
Transaction log (TLOG) backups should be taken frequently to maintain a reliable point‑in‑time recovery window.
During initial setup or when transaction log gaps are detected, take a transaction log backup followed by a full backup.
Snapshot creation requires a running cluster with stable data. Snapshots cannot be taken while a restore operation is in progress.
These practices help ensure reliable recovery and minimize the risk of data loss.
