> System must be tolerant to faults:
> # Backup operations MUST be atomic (no partial completion state in system table)
> # Process must detect any type of failures which can result in a data loss (partial backup) in a backup destination
> # Proper system table state restore and cleanup must be done in case of a failure
> # Additional utility to repair backup system table and corresponding file system cleanup must be implemented
