We're running a Bitbucket container (atlassian/bitbucket-server:4.2) and using the diy backup script to prepare backup artefacts.
For a time everything was peachy but recently this error message is cropping up in the logs:
[http://localhost:7990] ERROR: Locking this Bitbucket instance failed
This happens after rsync copies the incremental changes to the temporary folder, that bit works fine. But because it can't lock it, it won't progress and create a backup.
This is relevant but there's no activity there.
