I'm running the dockerised version of YouTrack.
There is a backup feature, which I can use 1) when I'm logged in and go to the backups admin page, and 2) via the built-in quartz scheduler.
But in most deployments this is not how it's done. I have a cron job that triggers backups for all my services at midnight - I want to include YouTrack in there.
I looked at `docker exec youtrack_youtrack_1 help` but it didn't mention a backup feature.
Is there a way to trigger a backup via the shell?
