It looks like there are two issues here:
1. The job was interrupted or the backup failed for that specific VM.
A snapshot will only exist on the VM while we are backing it up. If the snapshot was taken, cleaned up and then performed on the next attempt, then there must of been an issue at the time we were backing up that VM. Otherwise we wouldn't have seen the second snapshot appear if the VM backup completed on the first attempt.
2. There was an issue processing the index files on the MediaAgent.
At the end of the backup job, the VSA will collect all the index files generated for the job and then push them to the MediaAgent Index Cache. For some reason there was an issue with the Indexing Service on the MediaAgent when handling these files.
Had this operation completed successfully, we should see the line "IDXCONNECT [uploadFilesToIndexCacheDir] succeeded" outputted to the logs.
Unfortunately there isn't too much more we can tell from the log snippets provided. We would need the vsbkp logs from the VSA proxy, and the indexing logs from the MA to get a better idea as to what went wrong.
If you could open up a case with us and upload the logs for Job ID 1012569, we'd be happy to review and provide an RCA on the issue for you.
Any questions, let me know.
