Backup Integrity

No option via the web interface

When you create a new backup for the first time, you see above settings form. If you provided the right server address and credentials, a drop down menu is available. You can select an existing folder there, or define your own directory in which the backups must be placed.

When you later check your backup settings, you notice only server address and credentials are available. No directory or folder option anymore; which might seem strange at first.

SSH to the rescue

Enable the SSH service on your NAS, if you haven’t done already (mine is turned off by default). You can find this setting in your Control Panel, at the section for Terminal & SNMP. Just enable the SSH service with default settings.

Now login your NAS via SSH. Open up a terminal (command prompt under Windows) and enter the following:

ssh [email protected]

Substitute jurian with your own username and nas.local with your NAS address. Now enter your password.

Next, modify the file which contains your backup configuration. Only a basic editorvi is an option in the terminal of Synology, so I’ll guide you through.

sudo vi /usr/syno/etc/synobackup.conf

Enter your password again and search for a line inside a [repo_1] heading (or [repo_2], etc, if you have multiple of these repos). The line starts with remote_bucket and move the arrow keys to place the cursor at the right line.

remote_bucket="My old directory name"

Now press the i key and change between quotes whatever the new name should be. Next, press Esc. Now save the file via a command, press the following key combo :wq.

You should have left the vi editor and you are back in the shell. Type exit to quit the shell. Do not forget to turn off the ssh service again.

Change directory at target location and test

You have now changed the backup target location at your NAS, but your target hasn’t been updated yet. So go to your target via a browser (I use OwnCloud, so there is a browser interface for all my data there). Change the folder name on the target exactly how you have entered the name on the NAS.

Backup Explorer

As a last step, enter DSM and go to your Hyper Backup application. There is a button called Backup Explorer, shown below:

If you enter the explorer, you must be able to browse your files, like below screenshot. If there is any error, you know the location on either your NAS or your target is not set properly and don’t match.

Deduplication

Change of source directoy

Hello,
my data layout has changed and I wanted to move the source folder <Source> into a parent folder. <Parent>
Currently the source for my Hyperbackup is <Source>.
A rename of the folder did not work, Hyperbackup complained saying that the source folder is gone.
Same when I moved the existing folder into the parent using synology’s file manager. It did not automatically adjust the paths.

Hence I have to add the <source> again under its new location under <parent>.
To repeat:
OLD path <Source>
NEW path <Parent>/<Source>

Question:
Will Hyperbackup’s deduplication mechanism realize the change, with the consequence that the new backup version is very small.
Or will it create a completely new big backup version, duplicating the files that were in the previous backup version ?

Result:
a) The backup process was slow, it took some hours for 340 GB.
b) Deduplication worked, because the size did not change.
