Realtime mirroring Stash instance to backup/failover instance

[Alexey_Efimov]

We used rsync, but it probably make wrong coping on high loaded and large repos. If you did not stop Stash, then rsync possible lost some internal data of git withint Stash. For example, some opened Pull Requests will broken after new Stash instance started. It will complain about merge-base, will reject sha1 hash as unknown, etc.

Is there any ways to perform hot backup on fly? Someone get it worked? Does someone used File Systems with snapshots support?

We perform rsync every one minute, and we used innobackupex database engine for mysql.

[Roger Barnes · Accepted solution]

At any given moment Stash can have active git, filesystem and database operations. Because of this, a clean hot-backup is not currently possible, even with filesystem snapshots. We intend to produce some better documentation and minor tweaks to the current backup-client based solution to allow for DIY backups with minimal downtime.
