It does seem easy enough to setup, but I am curious about the restore process. What is the process?
I think this is getting discussed in 2 separate places...
Like with all things Linux, there's plenty of ways to skin this cat. I just use dd and then use balena to restore the images.

Your correct, there are plenty of ways, i was just curious on how Cezi_86 was doing his restore
I installed the backup plugin and want to backup ONLY the OS system disk not my shared folders - I don't see the option of the OS system disk to backup. I only see my shared folders. How do we backup and restore ONLY the boot SYS disk?
I installed the backup plugin and want to backup ONLY the OS system disk not my shared folders -
It is my understanding that dd command in Backup Plugin is for OS backup only. I use "dd full disk" to backup mine.
(EDIT: First you need to create a shared folder to backup your OS/Boot files and then choose this folder as "Location of the backup files". ( I named mine "OSBackup') Then you need to choose the "dd" or "dd full disk" Method. Then hit the save button. Wait for changes to be made. Then hit the backup button. Soon you will see your backed up files in the shared folder you just created for this purpose. )
and these are the files that show up in my shared folder:
Thanks for showing it - I am not getting that OS option populated - i get only my shared folders

Not sure if you were referencing me, but correct. The shared folder is just where you save the image.

OK. Thanks
I am not thinking of backing up the OS on the shared system folder but to my local drive - I only want to back up the ONLY the OS configuration and not the entire OS drive...
if the system dies then I lose those backups. Is there a way to backup directly to my local drive and restore it back from there?
Edited:
I created a backup folder and share it and give permission etc. and tried to execute the backup process but I get an alert 500 error message. I wonder what am I doing wrong?
I missed a step in the config - I forget to save first... It's working.
Thanks and sorry for mistake
I used only the DD option to back up ONLY the OS part of my boot drive. It looks like it's taking a very long time to backup ONLY the maximum of 8gb of the boot system disk. My current boot disk capacity is a 500gb laptop disk. I am monitoring the backup of my OS backup shared folder and I can see that the xxxxdd.gz files is growing after 45 minutes and counting... I wanna think that cloning the entire disk might be faster? Any thoughts on this?

How? It is just using a dd command to backup the main OS partition when you pick DD and the OS drive when you pick DDFULL. Unless you changed the root device line...
I didn't change or type in anything... they are all valid options I took. Select my backup, shared folder, selected dd option and hit backup.
It was still counting after 90 min I decided to shut the system down...

How big is your boot drive? ( EDIT, NOTE: It is my experience that both "dd" and "full" backup the entire size of the drive. When i was using 128GB SSD as boot device my backup operation ended only after 128Gb was written. Then I switched to 32Gb pen drive for OS and my backups was faster and ended at 32gb.)

Output from the backup? All I can do is guess without it. You can run sudo /usr/sbin/omv-backup from the command line too.

That's good to know... Thanks. How long did it take to backup your 128gb OS drive. My OMV OS boot disk is a laptop 500gb disk capacity. I locked the system down after about 90 minutes , it was not finished this is the output after about that 90 minutes zie screeshot

What will this "sudo /usr/sbin/omv-backup" line do exactly? backup only the 8gb OS SYS or the entire boot disk? and where will the backup files going?

The same thing that the Backup button in the plugin and cronjob do. It is the heart of the plugin that does the backup work. It has no arguments because it reads from the OMV database. Read the script if you want to know more.
backup only the 8gb OS SYS or the entire boot disk?
It does whatever you have the plugin set for.
and where will the backup files going?
Do you think I would give you a command that would backup random things to a random location?

NsinghP when last was your experience? I still have no clue what's going on with the backup of ONLY the OS sys disk and not the entire boot disk space. Is there is step by step tutorial on this?

I don't think you understand what dd does. dd creates an image of the entire source it is given, regardless of how much space on that source is used or unused.
Exactly what does this mean? "backup of ONLY the OS sys disk and not the entire boot disk space."

Last couple of times that I have run either the "dd" or "dd full disk" command on my server it has proceded to backup the entire capacity of my System Disk. (I'm not sure, but it may have something to do with how the disk is partitioned. If the entire disk is one partition then it makes sense to me that both "dd" and "dd full disk" will backup the entire capacity of the disk. OMV Gurus here will know more on this.) Here are the screenshots from my use of "dd" command just now: (It took my system 9 Minutes to backup 32Gb boot Pen drive)
And here is the screen shot of "dd full disk" method: ( It took my system 10 Minutes, and this time it wrote 31Gb as opposed to 29Gb of "dd' Method)

OMV says the OS sys disk space is about 8gb and if I have a capacity of 500gb boot disk then that means I have about 492 gb extra free disk space.
I was wondering how to backup ONLY that 8gb of the OMB OS space and not the remaining 492gb.
If I understand you correct "DD" or "DD full disk" does the same as NsinghP explains? If yes, then I wonder why the options
