Rsync to backup storage drive

snuckleton · 1. März 2014

I know this is not the best plan for backing up a storage drive...

I have two 3T drives in the system. One will act as a backup of the other. I realize it would be better to have the backup as an external drive or remote server.
I have several shares defined on the source drive.
I have one share on the target (backup) drive called omv-backup.

I'd like to use rsync to do an automatic backup of some of the shares from the source drive and drop them into the 'omv-backup' share on the target drive.
But I want them to go into uniquely named subdirectories of the backup drive - ideally the subdirectory name would be the sharename from the source.

I don't see a way to do this by setting up rsync jobs in the web gui.

If I had separate shares on the target drive pre-defined for each share on the source drive, then that would probably work.
But I am trying to get all the backups to live under that one share 'omv-backup'

Am I missing something in the configuration of the rsync jobs that might allow me to do this?

No Problem with that. Better than no backup.

If you copy a folder called 'peterparker' from a to b, it still is named 'peterparker' on the target location, so whats the problem?

I'm not used to setting up rsync Jobs via the GUI. For excluding folders from the rsync job, see: http://forums.openmediavault.o…wtopic.php?p=32201#p32201

Why? Folder names stay the same. See above for excluding folders from the rsync job.

At the moment I don't see what should restrain you from dooing that. Maybe you can specify a bit more where the problem is.

David,
My objective is to use the GUI to set up these rsync jobs. I have no doubt that one could get the desired results by setting up an rsync shell script and scheduling it to run. But I want to use the OMV Gui to set this up, if possible.

The issue is the GUI seems to constrain the jobs as follows. Assume I have shares defined on the source drive called A, B, C. I have a share on the target drive called OMVBACKUP. I want to populate that target drive with OMVBACKUP/A/*, OMVBACKUP/B/* and OMVBACKUP/C/* From the GUI I can pick a share for the source (A, B, C) and a share for the target (OMVBACKUP), but the gui will set up the rsync job so that I don't get then name of the share as a subdirectory under OMVBACKUP. Instead the contents of A, B and C are dumped directly under OMVBACKUP.

There is an inelegant way around this that still makes use of the GUI.
Create on the target drive a share called OMVBACKUP_A, OMVBACKUP_B, OMVBACKUP_C. Then create the three rsync jobs.

I'm just trying to avoid creating an explicit OMVBACKUP_X share for each source share.

I have to check this myself. This could take a couple of days due to lack of time.

So, finally I found some time to test this. And it seems it should be really easy for you:

My Setup:
4 shares, A, B, C, D on one disk, OMVBACKUP on another

rsync job (see attachment) copies A, B and C to OMVBACKUP

David,
Thanks for the reply. In the job you defined in the gui, do you end up with this on the OMVBACKUP share?
OMVBACKUP/test/stuff in test
Or do you get
OMVBACKUP/stuff in test

davidh2k · 21. März 2014

The shared folder "test" is the whole drive ( / ). So you end up with anything that is on the drive, except D.

David,
Using the root (/) share is the key I was missing. Now it is working as desired. Thanks for your help.

You're welcome.
