Hello @olivierlambert, @bastien-nollet, Hello Everyone !!
I used vhd-cli with its new arguments and it worked ok.
vhd-cli check --chain 'file:///run/xo-server/mounts/11934fec-f3a1-4f7f-a78d-00eeb1b39654?useVhdDirectory=true&encryptionKey=%22O1xt1ZTRE%5Qq%3X%3D1NZ%26%3ZZQo8%2DD%29s5xt%3OOko%22' 'xo-vm-backups/abc3e130-923e-619e-4fdc-59bcda088586/vdis/cecc4489-722a-4f79-b5e6-c050f63f2761/d489173c-028a-46f0-b712-f4a7c5594c8f/20260108T160552Z.alias.vhd'
ok: xo-vm-backups/abc3e130-923e-619e-4fdc-59bcda088586/vdis/cecc4489-722a-4f79-b5e6-c050f63f2761/d489173c-028a-46f0-b712-f4a7c5594c8f/20260108T160552Z.alias.vhd
But I discovered that using vhd-cli in this way only checks the physical structure of the alias.vhd file. It doesn't check the integrity of the blocks or the total number of blocks to detect a missing block. (It doesn't work like it does with huge monolithic .vhd files, where it detects errors with the slightest modification.)
So I opted to split the solution:
I check the integrity of the filesystem where the files are stored (using btrfs scrub).
I verify that the number of blocks written in the backup is correct (that no blocks are missing).
I verify that the written blocks haven't been modified since they were written.
For point 2, I found (AI) that I could use "vhd-cli info" to find out the total number of blocks in the backup (I don't have much information about it), but when I run it, I get the following error. I suspect it doesn't work with (Encrypt all new data sent to this remote):
vhd-cli info --chain 'file:///run/xo-server/mounts/11934fec-f3a1-4f7f-a78d-00eeb1b39654?useVhdDirectory=true&encryptionKey=%22O1xt1ZTRE%5Qq%3X%3D1NZ%26%3ZZQo8%2DD%29s5xt%3OOko%22' 'xo-vm-backups/abc3e130-923e-619e-4fdc-59bcda088586/vdis/cecc4489-722a-4f79-b5e 6-c050f63f2761/d489173c-028a-46f0-b712-f4a7c5594c8f/20260108T160552Z.alias.vhd'

Could you please help me with this? I'm not sure if I'm on the right track. Perhaps there are other ways I'm missing.
