Using your LinkStation
Backup operation modes
Three backup operation modes are available.
Normal Backup
All files in the source folder are backed up to the destination folder.
Overwrite Backup (Append Backup)
The first time the backup runs, it backs up all files in the source folder just like a normal backup.
If later, file A is added to the backup source and file B is deleted, the next backup will add file A,
but file B will not be deleted from the backup destination. This will use more space on the backup
destination because of the files that are not deleted.
Overwrite Backup (Differential Backup)
The first time the backup runs, it backs up all files in the source folder just like a normal backup.
If later, file A is added to the backup source and file B is removed, the next backup will add file A
and delete file B. This uses the same space on the backup destination as a normal backup.
The following types of folders may be used as either backup sources or backup destinations:
• Shared folders on your LinkStation, including attached USB drives, but not including the info
folder
• Shared folders on a different TeraStation or LinkStation on the local network, but not USB drives
attached to it
• Shared folders of a TeraStation or LinkStation on a different network that has been selected
manually by IP address, but not USB drives attached to it
Notes:
Before using a folder for backup, navigate to [Shared Folders] in the Web Admin interface and
check [Disk Backup] for [Shared Folder Support].
Subfolders of shared folders are not supported for backup.
To make a TeraStation or LinkStation that is on a different network available for use as a backup
target, navigate to [System] - [Backup] - [View NAS Devices] in the source LinkStation's Web
Admin interface and add it by IP address.
