Chapter 5 Backup
Network
Backup Modes
The following types of backup are available from this TeraStation. To restore data from backup, refer to the
"Restoring Backup Data"
Full Backup
All files in the source will be backed up to the destination. You can specify how many backup versions to keep from
1–400, or select "Unlimited" to keep all backups until the drive is full. If you specify a number of backup versions,
the backup destination folder should be on the same TeraStation or on an external USB drive attached to that
TeraStation.
The backup data will be stored in the folder whose name will be the backup date and time.
• Folders available as backup sources:
◦ Shared folder on the backup source TeraStation*1
◦ USB drive connected to the backup source TeraStation*1
◦ Shared folder on another Buffalo NAS device*2
◦ Shared folder on another rsync-compatible device
• Folders available as backup destinations:
◦ Shared folder on the backup source TeraStation*2
◦ USB drive connected to the backup source TeraStation*2, 3
◦ Shared folder on another Buffalo NAS device*2, 4
◦ Shared folder on another rsync-compatible device
*1 You can select up to the second level of folders. However, if the folder name of a second level folder contains
symbols, that folder may not appear as the target folder.
*2 The folder should have the "Backup" checkbox selected under "LAN Protocol Support" on the shared folder
settings.
*3 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, use Btrfs, XFS, or ext3
file systems.
*4 If the "Inherit subfolders' access restrictions" option is selected when creating a backup job, the device should be
a Buffalo NAS device whose subfolders' access restrictions is available.
Overwrite (Incremental)
The first backup job runs like a full backup. As each subsequent backup job runs, only files that have been changed
since the last full backup will be backed up, but any files deleted from the backup source folder will also remain in
the backup destination folder. The folder structure in the backup destination folder will be the same as the backup
source folder.
