The Options:
Backup Mode:
Normal Backup:
Saves as "yyyymmddhhmm\sourcename\data". Makes a new folder for each backup.
Overwrite Backup (Complete/Append)<labeled incorrectly as the first "Overwrite Backup (Complete/Differential)" on Linkstation Pro, Linkstation Live, Terastation Pro II, and Terastation Live>:
Saves as "_backups\sourcename\data". Does a complete backup every time, if a file is on the destination that is not on the source, it will not be deleted.
Overwrite Backup (Complete/Differential):
Saves as "_backups\sourcename\data". Does a complete backup every time, if a file is on the destination that is not on the source, it will be deleted.
Overwrite Backup (Append):
Saves as "_backups\sourcename\data". Does a complete backup the first time, subsequent backups only send the changes. If a file is on the destination that is not on the source, it will not be deleted.
Overwrite Backup (Differential):
Saves as "_backups\sourcename\data". Does a complete backup the first time, subsequent backups only send the changes. If a file is on the 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 files already existing on the share. This is useful if you want a backup that seems to be mirrored exactly in structure. There will be issues if you backup 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 network bandwidth 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 all nearly the same interface as Linkstation Pro. Have some of the same typos as well.
- Trashbox on source is backed up to destination (only tested on LSPro so far).
Sources
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 not exist on the backup source are deleted without any beforehand confirmation. Please be careful not to miss important data.
- In any operation mode except for normal backup, all data are overwritten to backup destination. Please be careful not to miss important data.
- Don't operate any file (change file name, delete and so on) in backup source folder while backup is performed. Otherwise, backup procedure may be faulty terminated
Behavior in each mode is as shown in the following table. Behavior differs largely depending on whether [Create folder from which backup source 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 Operation mode | Create folder from which backup source can be identified | Backup source folder | Backup Result | Description |
|---|
| Normal | Set (mandatory) | /share | /target/(date&time)/share | Backup all files/folders under "/share". |
| Normal | Set (mandatory) | /share/folder | /target/(date&time)/share/folder | Backup all files/folders under "/share/folder". |
| Overwrite(Complete/Append) | Set | /share | /target/_backups/share | Files/folders existing only on / target/_backups/share are not deleted when in backup. And all files are overwritten every time when backup is performed. |
| Overwrite(Complete/Append) | Set | /share/folder | /target/_backups/share/folder | Files/folders existing only on target/_backups/share/folder are not deleted when in backup. And all files are overwritten every time when backup is performed. |
| Overwrite(Complete/Append) | Not Set | /share | /target | Files/folders existing only on target/ are not deleted when in backup. And all files are overwritten every time when backup is performed. |
| Overwrite(Complete/Append) | Not Set | /share/folder | /target/folder | Files/folders existing only on target/folder are not deleted when in backup. And all files are overwritten every time when backup is performed. |
| Overwrite(Complete/Differential) | Set | /share | /target/_backups/share | Files/folders existing only on target/_backups/share are deleted. And all files are overwritten every time when backup is performed. |
| Overwrite(Complete/Differential) | Set | /share/folder | /target/_backups/share/folder | Files/folders existing only on target/_backups/share/folder are deleted. Even if there is any difference on /target/_backups/share layer, the files on the layer are not deleted. All files are overwritten every time when backup is performed. |
| Overwrite(Complete/Differential) | Not Set | /share | /target | Files/folders existing only on /target are deleted. And all files are overwritten every time when backup is performed. |
| Overwrite(Complete/Differential) | Not Set | /share/folder | /target/folder | Files/folders existing only on target/folder are deleted. Even if there is any difference on /target layer, the files on the layer are not deleted. All files are overwritten every time when backup is performed. |
| Overwrite (Append) | Set | /share | /target/_backups/share | Files/folders existing only on /target/_backups/share are maintained as they are (not deleted). Only files which file size or time stamp has been changed are copied. |
| Overwrite (Append) | Set | /share/folder | /target/_backups/share/folder | Files/folders existing only on /target/_backups/share/folder are maintained as they are (not deleted). Only files which file size or time stamp has been changed are copied. |
| Overwrite (Append) | Not Set | /share | /target | Files/folders existing only on /target are maintained (not deleted). Only files which file size or time stamp has been changed are copied. |
| Overwrite (Append) | Not Set | /share/folder | /target/folder | Files/folders existing only on /target/folder are maintained (not deleted). Only files which file size or time stamp has been changed are copied. |
| Overwrite (Differential) | Set | /share | /target/_backups/share | Files/folders existing only on target/_backups/share are deleted. Only files which file size or time stamp has been changed are copied. |
| Overwrite (Differential) | Set | /share/folder | /target/_backups/share/folder | Files/folders existing only on target/_backups/share are deleted. Even if there is any difference on /target/_backups/share layer, the files on the layer are not deleted. Only files which file size or time stamp has been changed are copied. |
| Overwrite (Differential) | Not Set | /share | /target | Files/folders existing only on /target are deleted. Only files which file size or time stamp has been changed are copied. |
| Overwrite (Differential) | Not Set | /share/folder | /target/folder | Files/folders existing only on / target/folder are deleted. Even if there is any difference on /target layer, the files on the layer are not deleted. Only files which file size or time stamp has been changed are copied. |
- Backup behavior is specified by the conbination of [Overwrite(differencial)] and [Create folder from which backup source can be identified]. Depending on conbination, it may not operate as you have expected.
