Windows Backup fails and make OMV unreachable every time

Hello all.

As the subject says.

I have a windows 7 x64 install on my PC, on which I have set up a Windows Backup schedule, and told it to backup to my OMV box. It creates an image of the C drive on my windows PC, as well as some select folders.

It used to work fine for the last year or two, but recently every time it tries to backup, it fails and I can no longer reach OMV. This means no web access to the GUI, no ssh tunnel from Putty, no accessing certain apps on my phone, etc. The only way I can get it back is to reboot the OMV box.

One thing that is kind of good is that this happens 100% of the time - so it's easy to test. I have disabled Windows Backup for the time being until I find a way around this.

Any thoughts appreciated!

Sorry for lack of info.

OMV 2.23 (I know it's a couple of fixes old, but it was happening with previous ones too). It is installed on a AMD kabini system, using a 2.5in HDD as the OS drive. I have separate storage drives in the box of course. It has been working fine for over a year, including backups (until recently).

Installing Backports kernel now to see if it will help - haven't been using it in the past year or so, and been fine. Happy to try.

Installing Backports worked!

I have no idea WHY it worked though, since it wasn't needed previously on this machine. Should I be concerned about some sort of hardware failure?

THANK YOU for your help by the way!
