I’m running v.2.5.25.0 on a linux client; server version 2.5.32. I’m getting errors every time the client tries to backup. /var/log/urbackupclient.log is a repeat of the following:
2024-04-11 14:13:34: ERROR: Creating snapshot of "/dev/nvme0n1p1" failed
2024-04-11 14:13:34: ERROR: File system vfat not supported
2024-04-11 14:13:34: ERROR: Creating shadowcopy of "/dev/nvme0n1p1" failed.
2024-04-11 14:13:34: ERROR: Creating shadow copy failed. See client log file for details.
nvme0n1p1 is mounted to /boot/efi and is vfat (nvme0n1p2 is mounted to / and is ext4). I’m fine without backing up /boot/efi; that can always be rebuilt.
How do I omit just /boot/efi from backups but still get everything else? I’m having a helluva time converting the instructions in the manual and on the interface from Windows to Linux.
The issue is probably the attempt to create a snapshot.
You could…
Ensure you are using file backups not images and then exclude /boot/efi/*.
You could create a prefile backup script
In /usr/local/etc/urbackup named “prefilebackup”
This will get executed for the client (and any virtual sub clients).
I wrote a test script that echod argument 3 (the virtual sub client name) to a temp file. I didn’t care what the scrambled name really was…I only wanted to test for it with one of my sub clients so I didn’t do this each time.
The script (once I new the value was 300 for my particular sub client)
Was this
! /bin/bash
If [ “${3}X” == “300X” ] ; then
/bin/tar czPf /temp/boot efi.tgz /boot
fi
exit 0
This gave me a compressed tar file of both /boot and it’s mounted contents.
So, I could exclude /boot/* from my backups coz I had the /tmp tarfile.
Overkill?
Maybe. But, I have had difficulty with Linux and images and mounted and snapshots.

I looked a bit into this problem and I think the easiest solution is to just fix it and make backup of /boot/efi work. Since this is a small partition I think it might be able to be backed up without any snapshots. Unfortunately vfat does not support FIFREEZE (fsfreeze --freeze /boot/efi), but I guess it can also temporarily be remounted read-only.
