• [Normal Backup]:
All fi les in the source will be backed up to the destination.
• [Overwrite Backup (Append Backup)]:
The fi rst time the backup job runs is just like a normal backup. Each additional time the backup job runs, if fi le A
was added to and fi le B removed from the backup source, then fi le A is added to but fi le B is not removed from the
backup destination. Over time, the backup destination folder will become larger than the backup source folder.
• [Overwrite Backup (Diff erential Backup)]:
The fi rst time the backup job runs is just like a normal backup. Each additional time the backup job runs, if fi le A
was added to and fi le B removed from the backup source, then fi le A is added to and fi le B is removed from the
backup destination. The backup destination folder is always the same as the backup source folder.
• [Management Backup]:
Each time a backup is executed, management information is stored, and only fi les that have changed are copied
or deleted. Data is retrieved from the previous backup fi le for fi les that were not changed (if the previous backup
fi le was corrupted, the fi le can no longer be referenced). This is used for making backups with limited space or for
referencing status at a particular point in time (for use for data snapshot applications).
You may select how many generations of data are saved from Unlimited or 1 to 10.
- [Management Backup] supports saving backups to destination folders on the TeraStation and connected
external hard drives.
- Backing up to a external hard drive changes the specified shared folders and shared folders on the external hard
drive to read-only.
- FAT formatted external hard drives are not supported for Management Backup destinations.
- When performing an incremental backup to an external drive formatted with NTFS, if the TeraStation is
restarted or disconnected from the drive, the data saved to the drive may suddenly become twice its normal
size. Reformatting all backup drives with EXT3 or XFS is highly recommended.
- If you back up data to an external hard drive with [Management Backup], do not connect the external hard
drive to another device and edit the data. Important backup files could be overwritten.
