Just keeps the data, but deduplicated. AFAIK,

Don't try to directly 'rsync' any Linux filesystem to a samba share as
a backup.  Samba will not store everything needed to recover (you'll
have your data, except for those files with names that are 'invalid' in
the windows samba world) but none of the ownerships/permissions will be
correct.

If you must use samba as the backing store, then use something like
Restic which stores the data in its own internal format and only

underlying backing store.

Excellent. Thank you for confirming. Restic also has this "check" function to detect inconsistencies, bitrot and other stuff. Sadly NFS did not work with my ancient NAS, so smb was what I had to work with, to mount it to my backup server. Would have preferred NFS though. =(
