I have a Time Machine backup stored on a Synology NAS that got corrupted for some reason (probably a power failure). The folder containing the sparsebundle is mounted on the Mac using smbfs.
I tried to run
fsck_apfs but it fails with the following message:
error: spaceman cib out of order: 13, expected 4
Space manager is invalid.
** The container /dev/disk5s2 could not be verified completely.
Is there a way to recover the space manager?
