The Options:
Backup Mode:
Normal Backup:
Saves as "yyyymmddhhmm\sourcename\data". Makes a new folder for each backup.
OverwriteBackup (Complete/Append)<labeled incorrectly as the first "OverwriteBackup (Complete/Differential)" on Linkstation Pro, Linkstation Live,Terastation Pro II, and Terastation Live>:
Saves as "_backups\sourcename\data". Does a complete backup everytime, if a file is on the destination that is not on the source, itwill not be deleted.
Overwrite Backup (Complete/Differential):
Saves as "_backups\sourcename\data". Does a complete backup everytime, if a file is on the destination that is not on the source, itwill be deleted.
Overwrite Backup (Append):
Saves as "_backups\sourcename\data". Does a complete backup thefirst time, subsequent backups only send the changes. If a file is onthe destination that is not on the source, it will not be deleted.
Overwrite Backup (Differential):
Saves as "_backups\sourcename\data". Does a complete backup thefirst time, subsequent backups only send the changes. If a file is onthe destination that is not on the source, it will be deleted.
Other options:
Create a file folder which would be identified by backup source:
If this is unchecked, any overwrite backup will overwrite filesalready existing on the share. This is useful if you want a backup thatseems to be mirrored exactly in structure. There will be issues if youbackup 2 shares to a single share
Use encrypted transfer:
Specify whether data should be encrypted when it is transferred for backup.
- Throughput is decreased if this encryption function is enabled.
- Don't use this function when backup destination is a USB hard drive.
Use compressed transfer:
Specify whether data should be compressed when it is transferred for backup.
- When backup is performed via network by using this function,transferring speed may increase in the environment where networkbandwidth is narrow. (It is not that backup all data into one archive).
- Do not use this function when backup destination is a USB hard drive.
Create backup log files:
Create log files of the backup on the source folder.
Backup task isn't cancel even error is occurred<"Ignore the errors and proceed back up anyway." on Linkstation Pro>:
If enabled, after a backup failure, subsequent scheduled backups will still be performed
Other Notes
- Linkstation Live, Terastation Pro II, and Terastation Live allnearly the same interface as Linkstation Pro. Have some of the sametypos as well.
- Trashbox on source is backed up to destination (only tested on LSPro so far).

From the "Help" Document on the Terastation Pro:
Backup Operation mode:Select backup operation mode among the followings.- Normal Backup- Overwrite Backup (Complete/Append)- Overwrite Backup (Complete/Differential)- Overwrite Backup ?Append Backup?- Overwrite Backup (Differential Backup)
- If [Overwrite(Differential)] is used, any files which does notexist on the backup source are deleted without any beforehandconfirmation. Please be careful not to miss important data.
- In any operation mode except for normal backup, all data areoverwritten to backup destination. Please be careful not to missimportant data.
- Don't operate any file (change file name, delete and so on)in backup source folder while backup is performed. Otherwise, backupprocedure may be faulty terminated
Behavior in each mode is as shown in the following table. Behaviordiffers largely depending on whether [Create folder from which backupsource can be identified] on backup option is set.
- The description below is explanation for the case when [/target] is set as backup destination folder.

- Backup behavior is specified by the conbination of[Overwrite(differencial)] and [Create folder from which backup sourcecan be identified]. Depending on conbination, it may not operate as youhave expected.
