Chapter 5 Backup
the backup job may not be properly performed. In such a case, select the default frame size (1500 bytes) for both
devices.
• You can also specify a hostname by a fully qualified domain name (FQDN).
• Windows-based TeraStations with multibyte characters in the hostname may not be detected as a backup
destination, and folders in these devices cannot be used as backup destination folders.
• Backup data, such as ".DS_Store" files, from macOS may include characters that cannot be read on FAT32-
formatted drives in its filename. For best results, reformat the drive before using it as a backup destination.
Backup Modes
The following types of backup jobs may be selected:
Type
Normal backup
Overwrite (incremental)
Overwrite (differential)
Management backup

drive could not be found.
Files included
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 a specific number of backup versions is
specified, the backup destination folder should be on the same TeraStation
that the backup job is configured from, or on an external USB drive attached to
that TeraStation.
The first backup job runs like a normal backup. In subsequent backups, files
added to the source as well as files deleted from the source are kept in the
backup folder.
The first backup job runs like a normal backup. As each additional backup job
runs, files will be added to and deleted from the backup folder. The backup
destination folder is always the same size as the backup source folder.
Each time a backup is executed, management information is stored, and
only files that have changed are copied or deleted. Data is retrieved from the
previous backup file for files that were not changed. This is useful for making
backups with limited space or for referencing status at a particular point in
time (for data snapshot applications). The destination folder for a management
backup should be a local folder on this TeraStation or on a USB drive attached
to it. The destination folder will be set to read-only. Do not use folders from
drives formatted with FAT.

Corrective Action
Check that the backup destination
USB drive is connected to the
TeraStation properly.
