Kopia stops snapshot

Support
1

I have (again) an issue, where KopiaUI just stopps a running snapshot, while providing this error message:

Error: upload error: processing subdirectories: unable to process directory "Library": processing subdirectories: unable to process directory "Application Support": processing subdirectories: unable to process directory "iMazing": processing subdirectories: unable to process directory "Backups": processing subdirectories: unable to process directory "00008020-000B551921C0802E": processing subdirectories: unable to process directory "c9": error writing dir manifest: c9: unable to write directory: unable to write content chunk 0 of DIR:Library/Application Support/iMazing/Backups/00008020-000B551921C0802E/c9: EOF: EOF.

I can successfully run a snapshot if I exlcude the iMazing folder, but that has been working before, so I’d rather have that back working. I also have debug logs from my Kopia server. Both of them are updated to the latest nightly…

This is what is in the cli-log when this happens:

That seems like either a backend write problem. Kopia was not able to write a pack file to its storage. What’s the backend and does retrying help? Are you using kopia server? If so check server logs around the same time.

3

I checked the storage, but I couldn’t find any issue with it. The backend is a XFS volume on CentOS running kopia server and the logs are from the kopia server at that time.

4

Can I somehow determine, which blob Kopia Server has trouble writing to? I am still a bit puzzled, that I am seeing this only for my client. My other MBP, which also writes to the same repo, doesn’t seem to have any issue.

5

Whoa… it actually looks like this is an issue with macOS Big Sur 11.2.x. macOS Big Sur seems to have some serious trouble with USB-C network adaptors in general and multi-port ones specifically. This morning I updates BS to 11.2.2 and I have not been able to get a snapshot to finish since.

Now, I have re-attached my USB-C-to-Thunderbold2 adaptor and plugged in a Apple Thunderbolt ethernet adaptor and… voilá… looks like my issues have gone.

What I can’t wrap my head around just yet, is why KopiaUI seems to upload a lot of data again… just like if the blobs on the repo have been wiped or zeroed out… could this even happen?

6

Well, it turns out, that macOS Big Sur, doesn’t finish a snapshot with any 3rd party USB-C LAN adaptor. I tried two:

DesertWest 7-in-1 with PD
Anker 5-in-1 w/o PD

both of them cause KopiaUI to fail a snapshot run. Still works with Apples Thunderbolt2 adaptor, though. I cannot say, that I had any other issues with those 3rd party adaptors, though.
