Sorry, it was my fault. I've a corrupted image and by mistake I used this one to try the diff-backup. I tried on another LXC container and it works fine :)
Thank you

This is strange.
I added this selftest command to ensure that this does work properly. This is what I receive:
./pve-5.3-9-diff-backup-addon selftest-lxc
Proxmox VE 5.3-9 - differential backup support, v3

This is destructive command that requires:
- the CT501 present
- and CT511 empty

Are you sure that this works before applying patches, as it seems to me that the layout of disks slightly different, thus why it fails.

No. Sorry maybe it wasn't clear.
It's the first time I'm using your patch. My server are still runing 4.4 (the patch has been applied without any error). When the backup occurs yesterday, it shown my this error.

I don't think that this is bug of pve-diff-backup. Did you try if you can backup and restore without patches applied?
