Backup Option Details
« on: October 08, 2008, 09:28:48 am »
   I have the HS-DH500GL LinkStation Live 500 Gb drive with the latest firmware version 2.10.

There are five backup options offered as follows ...

Normal
Overwrite Backup (Complete/Differential)
Overwrite Backup (Complete/Differential)
Overwrite Backup (Append Backup)
Overwrite Backup (Differential Backup)

[Yes, the 2nd and 3rd options show up identically]

I have not found the help screen or the manual very helpful in explaining the details of each option.
Can I get that information via the forum?

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).

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 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.

From the "Help" Document on Linkstation Pro:

Backup Function Mode
Backup mode selection:
*Normal Backup
*Overwrite backup
*Overwrite backup (All/Updated)
*Overwrite backup (Additional)
*Overwrite backup (Updated)
*"Caution: Overwrite backup will delete original."
*"Caution: Backup mode (except Normal mode) will not save any previous backup data."
*"Caution: Do not access any backup file(s) during the backup. It may cause an error."

Hi Paul,

 

I have one question to what you said.

 

The last option :

" 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. "

 

Does it mean that new files, isn't added to the previous backup ??

 

BR

Peter

I would of course run a test, however they should not be deleted.

Who talked about deleting ??

I'm talking about adding.

 

And yes, i could run a test, but i have trouble enough to get it to work in the first place. I just wanna know how it is suppose to work.

When would you choose a complete/differential backup over differential backup?  Since the initial backup on a differential is a complete one and subsequent backups copy over the changes, it seems like the end results of both of these methods would be the same: a backup destination synchronized with a source destination.  The only difference I would imagine is that the complete backup takes longer.

 

What am i missing?

   Stupid question but when is Buffalo going to come out with an update that has the backup options labeled correctly?

   Why do you say that we shouldn't use compression when backing up to a usb drive?

The compression is in the transport stream, not the actual data. Compression only helps speeds over a network backup, not to USB.

Doesn't look like the menu was fixed in firmware release 2.11 which was recently released. I am now using 2.11 and the backup menus are the same. Also, I cannot cancel a backup no mater what I do.

 

When is Buffalo going to get serious about product support. This is the last product I will ever purchase from Buffalo.

Yeah, Im on firmware 2.14 and they still haven't fixed it. What's up with that?

 

Also, when there is any kind of an error message on the machine it stays there until you reboot. That's ridiculous.

 

Add to that the fact that it doesn't speak NTFS and you've got some serious drawbacks.
