Runing UrBackup 2.5.33
No problems backing up Windows PC’s, but none of my Debian 12 Linux VM’s will NOT work
I installed the clients via the “Add New Client” functions
Install works fine.
If I try to initiate a backup through the Server UI - just fails
Hi Dave, and welcome…
You should be able to go into the Logs tab to see what the logs say for the backup/s in question - bear in mind that you might need to change the default filters to see it…
The other thing that springs to mind would be how you have the clients set up; obvs can’t just have one group, as Linux doesn’t have a C:\ drive to back up, and using “/” would cause Windohs to have issues…
For my clients, which are a mix of Linux and my Windohs lappy for work, I use groups for managing centrally and scaling, but would need more info to work out with you…

This is from the client log. Seems like the urbackup client process has the ports open…

Where is the urbackup server installed? Linux, Windows? What version of the OS?
And please send the console output showing which ports are being listened to on the server. Also, include the FW rules.
Based on the screenshots and the output, I’m going to presume it’s a Plex “server” running on a Linux system…
Would also presume that the firewall rules are probably okay, given the Windohs clients are working as expected; that is, of course, presuming they’re either inside the network or just using the same access as the Linux systems are…
Thanks for your response.
I’m all sorted now.
Yes, it’s a plex server, in a VM hosted by one of my Proxmox servers. The other Linux machines were additional virtual machines in my two Proxmox server environment.
Just couldn’t find out the reason why, but as my “data” volume for plex (and the other vm’s) was a different volume to my “boot” virtual disk(s), I just blew away my boot disk(s) and built new ones with latest Ubuntu distribution.
Followed the same procedure to install the Urbackup client and no problems at all, so I think it’s something specific to Debian 12.
