For all of my VMs, backups always succeed.
For some of them however, the result is bad:
Other observations:
Has anyone seen something similar?
If yes, what may be the problem?
If no, does anyone know how to debug a backup or verification process?
For some of them however, the result is bad:
- they fail verification
- the first stored disk cannot be downloaded, the http response is:
- unable to read fixed index <filename> - Unable to open fixed index <filename> - got unknown magic number
- of course, the file restire function also gives an error:
- Starting VM failed. See output above for more information. (500)
- I failed to find any further information in the logs (or in the response).
Other observations:
- Repeated backups after a bad result usually (but not always) also create a bad result.
- Repeated backups after a good result (even if there was a bad result before that) usually (but not always) also create a good result.
- Migrating a VM to another node and then doing a new backup sometimes creates a good result.
- Setting up replication (and waiting for it to finish) for a VM and then doing a new backup usually creates a good result.
