Hi,

We have a LinkStation Pro Duo. The built in backup funtionality is not sufficient for us as we need to keep revisions so we can go back to a specificversion of a file.

 

I therefore need to copy the files off the Linkstation to another machine which will run the softweare that backs up the files. Is there a way to rsync the files off the linkstation to another machine? I dont really want to try to copy all files off every night even if they havent changed.

 

Thanks

You can run back up jobs to another linkstation or a USB hard drive formatted in to XFS by the Linkstation.

below are some of the back up options. 

 

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).

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 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 Operation mode	Create folder from which backup source can be identified	Backup source folder	Backup Result	Description

Hey,

 

I have few questions, because we bought recently Linkstation Pro Duo.

 

We are using Linkstation Pro Duo every day and we are adding and changing files there every day.  I have backed up my Linkstation Pro Duo to USB disk. But i would like to backup all data once a week to that USB disk. I do not want to do complete backup every time, because that takes a quite long time. I am interested of adding changed and new files to backup USB disk. And if we delete something from the Linkstation Pro Duo, then we want that backup will also delete these files from backup USB disk.

 

Now the question, which backup mode i shoul use? Differental, Append or i have to run them both ?

 

Greetings

For your needs I would run Differential.

   Does Append Backup keep multiple versions of the files changes? If not, is there any method to do this?

There is no versioning in the built-in backup software. You may be able to effect file versioning with a backup software to the NAS; however, for backups from NAS to NAS or NAS to USB, versioning is not an option.

   

You mean Overwrite Backup (Append) will make backup of all files with changes and will overwrite previous files?

 

Can I conclude that both Overwrite Backup (Complete/Differential) and  Overwrite Backup (Differential) are actually giving the same result of mirroring/sync with source, just that Overwrite Backup (Complete/Differential) will re-copy everything no matter what, while Overwrite Backup (Differential) will only copy files that have been changed since last backup (after doing a complete backup the first time)? Can I summarized as below?

 

1. Normal Backup = Make duplicated complete backup everytime.

 

2. Overwrite Backup (Complete/Differential) =  Make complete backup that replace previous backup completely

 

3. Overwrite Backup (Append) = Make complete backup the first time, then make backup on files that are changed. Deleted files will not be deleted on the backup.

 

4. Overwrite Backup (Differential) = Make complete backup the first time, then make backup on files that are changed. Deleted files will be deleted on the backup.

 

It will be more useful if there is another option for best of both worlds:

 

5. Overwrite Backup (Append/Differential) =  Make complete backup the first time, then make backup on files that are changed into new folders with date stamp just like Normal Backup but without having to duplicate files that have not been changed. Deleted files will not be deleted on the backup. This will ensure that we get to keep multiple versions of all files without having multiple duplicate files.
