cannot read from / mount Time Machine sparse bundle
Here's my problem:
I've lost data which should be on a Time Machine Backup. However, I do not succeed to restore it.
My TimeMachine Volume is a NAS. Writing backups to it has stopped to work for some time now, but the relevant data should have been written to it. The NAS still works fine for reading/writing, including TimeMachine Backups from other computers.
I can see the sparsebundle in the finder. When trying to mount it with Disk Image Mounter, I get an error. "Das angeschlossene Medium konnte von diesem Computer nicht gelesen werden" (not readable by this computer).
On the internet, I have found the recommendation to try "hdiutil attach -nomount -readwrite ...", which results in:
"/dev/disk2"
Then, the image becomes visible in disk utility. When clicking first aid, I'm immediately told that first aid was successful.
I still cannot access my backup files.
Then, I tried "fsck_hfs -drf /dev/disk2".
This is the response:
journal_replay(/dev/disk2) returned 22
