on some hosts the ZSTD backup compression is not working?
any idea why ?

this is the error?
Parameter verification failed. (400)

compress: value 'zstd' does not have a value in the enumeration '0, 1, gzip, lzo'

upgrade proxmox to latest version on all nodes.

what is your pveversion -v ?
most nodes are 6.2-11 (oldest is 6.1-2) (upgraded but did not rebooted yet)
probably the packages are just to old.. zstd is only available with 6.1-11
