Backup Restrictions
• If you are using Overwrite-Differential Backup to back up to a external USB drive formatted with FAT32, it may
overwrite even if there are no differences in the data. If the second of the date when the file was created is an odd
number, data is overwritten regardless of any differences in the data.
• To back up data between TeraStations or LinkStations on a network using jumbo frames, make sure that both devices
are configured to use identical (or similar) Ethernet frame sizes. If Ethernet frame sizes of these are significantly
different, the backup job may not be properly performed. In such a case, select the default frame size (1518 bytes).
• Backing up files or folders with multi-byte characters in their names may cause log files to output incorrectly.
• If you change RAID settings or reformat a drive, you must redo all backup settings for the drive. If another TeraStation
tries to use the drive as a backup destination without redoing the backup job, an error message will be displayed.
• If the firmware for the backup source and/or backup target is not the latest version, occasionally shared folders with
names that are 20 bytes or more cannot be selected. In some cases, this problem may be fixed by downloading the
latest firmware version for your TeraStation from www.buffalotech.com.
If a scheduled backup fails (I54)
Check the startup state, network status, shared folder settings for the backup source and target folders on the backup
source and target LinkStation and/or TeraStation.
■ Checking the startup state
• Check that the backup source and target LinkStation and/or TeraStation are not being shut down during the
scheduled backup.
• If the sleep timer is enabled for the backup source or target LinkStation or TeraStation, disable the timer and try
rerunning the backup. If the backup failed, the backup target may not have been recognized properly. Check the
network and USB connections at the backup target. If the backup succeeded, there may have been a problem with
the sleep timer setting. Correct the sleep timer settings or disable the sleep timer.
Note:
If either the backup source or target LinkStation or TeraStation is in standby when a scheduled backup job begins, the
backup job will fail.
■ Checking the network status
• Check whether the backup source and target LinkStation and/or TeraStation can be found using System - Backup -
View NAS Devices. If it cannot be found, check the network settings of the backup source and target LinkStation and/or
TeraStation. Also check whether any network cables are disconnected.
■ Checking the shared folder settings
• Confirm that Disk Backup is checked for "Shared Folder Support" in the shared folder settings of the backup source
and target LinkStation and/or TeraStation.
