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.
Individual database restores cannot be performed. The job will fail.
The following options are not applicable to restores of Exchange 2003 snapshot backups. Exchange will use the soft-recovery process when restored databases are mounted.
Restore all transaction logs; do not delete existing transaction logs (no loss restore)
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
Path on Exchange Server for temporary storage of log and patch files
Data cannot be restored from a snapshot backup to a Recovery Storage Group (RSG) (Exchange 2003 only).
