Backing up the OMV drive before going from OMV4 to OMV5

Hi,

my NAS (based on a j4105) was running pretty well for a year now with OMV4. I saw the possibility of upgrading to OMV5 with a script.

To be on the save side, I wanted to create a backup copy of my system disk.

I found this instructions from Techno Dad:

The problem is: OMV is currently on a 256GB SSD and I just bought a only 240GB, and since it is a byte by byte copy the new one is too small I assume?

Do I need then go over clonezilla and follow this rather old instructions here?

RE: How to move OMV system to another drive

Or could I follow Techno Dads instructions like for the SD card with a external USB housing?

Windows did not recognize the drive with a letter after the failed DD (Option 1) try and also was not able to delete the volume in disk management.

If this approach would work I could swap the main disk to the 240GB and then create the automatic task like in the Option 1.

I would be happy for an advice this. Since my kids series are on the data drive and also the PVR is saving there, I only have a limited "window of opportunity"

Thanks in advance.

Thanks, but it did not solve my problems completely:

- yes I did a backup of the OS Drive to the Data Drive

- I was not able to clone the 275GB (not 256GB btw) drive to the 240GB new drive

--- neither with disk to disk option (disk size too small)

--- neither with restore image (restoring to new disk)

Total occupied image size is ~16GB

Any other options?

Thanks guys, I skipped the idea with mirroring the drive for now.

Saving the image on the data disk worked well (and was also needed when upgrading).
