Backup feature with-in openmediavault-compose plugin

Hello everyone, first post here, feeling a bit shy .

I had my first contact with OMV a few months ago, have been reading and learning so far. I was able to deploy around 15 containers using openmediavault-compose, including nginx-proxy-manager to access some of the services from the outside.

I though it would be now a good idea to start backing-up the whole docker ecosystem. So I referred back to the guide I used at the beginning to install and config everything (here) but I wasn't able to find much information about how to do it. Only the section backup_appdata folder throws a couple of comments there and I find my self with a few question marks. Of course I tried to research the forum and googled and so on... but I got lost in a ocean of rsyncs, Rsnapshots, cron jobs....etc.

I better ask before moving on. Using the build-in functionality of the omv-compose plugin seems convenient since, as far as I understood, it can stop the containers, synchronise the files..etc and get configured with-in the GUI itself.

My questions are:

• is it a good idea to use such feature or should I go down another path?
• what exactly does the omv-compose backup plugin functionality back-up? I though it was only going to be the compose files but after running it manually I saw the folder getting filed up with lots of stuff (in a way I can't understand)
• When choosing to back-up the system weekly It seems I can't specify when do I want to do it. Does the feature decide by it self?
  

If someone could help me please understand a bit further how it works or maybe pointing me to a more extensive documentation would be sufficient.

PS: I know the backing strategy might depend a lot on what kind of containers do I run. I can specify them if needed.

Thank you very much

thanks chente .Will do

The Wiki was very helpful. Thanks!

There is something which I still don't know how to do. The wiki says: "Schedule the time of execution using the date and time options." But selecting "Weekly" from the "Time of execution" dropdown leaves all date and time inputs disabled (see screenshot in post #1). Only when selecting "Certain date" they become enabled.

Is there a way to specify when (day of the week and time) should the backup take place by selecting "Weekly"?

thanks

Thanks again for your time and effort

I'm sorry to come back here for the same topic (is it ok to use the same thread, since it is marked as resolved?)

The schedule task is not firing automatically on the set date:

I saved and applied the changes. Is there some way I can debug this?
One thing I noticed when running the job manually is that it somehow waits for confirmation before running, could this be the cause of not running automatically?

After clicking on start, the process begins and finishes successfully.

yep, that work. Thanks again chente

Thanks ryecoaaron I'll pull then
