Error on restore: BLOB not found?

Hi there,
i wanted to restore some files from a snapshot, but i doesn’t work, i get this error:

**Error:** error restoring: restore error: copy file: error creating file: unable to open snapshot file for d:\test2\name.xls: unable to open object: 658880848b9a44387874ea6830be9e45: unexpected content error: error getting cached content from blob "pad138e4739e07d0bd46c52553405ae37-s9d9f5dc5c435fafb119": failed to get blob with ID pad138e4739e07d0bd46c52553405ae37-s9d9f5dc5c435fafb119: BLOB not found.

What can i do now?

I run a maintenance in the Windows/cmd:

ERROR error rewriting contents in short packs: failed to rewrite 9 contents

I searched for the missing blob’s in den repo, but they are not there.
How can happen this? I use the Hetzner Storagebox for it which run on ZFS. So silent corruption can not be the reason.

What is now, is my whole backup dead now?
The normal maintenance run all the time without a problem.

I find that really terrible. I think i have a backup and when i need it, it’s broken.
The good speed and the great features are useless if it is not 100% stable in the end.

I am frustrated now.

Did your repository get disconnected? What does “kopia repository status” say?

No, not disconnected. I can make snapshots and “Periodic maintenance” run every hour without errors.
