Note the following when restoring Exchange data from snapshot backups:
-
If circular logging is enabled, only point-in-time, loss restores are possible. Roll-forward, no-loss restores cannot be performed.

Restore all transaction logs until point-in-time; skip transaction logs after this time
-
Purge existing data and restore only the databases and transaction logs from the backup sets
