When asking Gitlab support on how to do a 3TB backup on ones on-premise Gitlab they reply use our tool that produces a tarball.
This just seams wrong to me on all levels. This tarball contains the postgres dump, docker images, repo data, GIT LFS, etc config and so on. Backing up TB of static data together with KB very dynamic data doesn't seam right. And then comes the issue of, we want to do a backup every hour.
I'd really like to know from others how they do it, to get a consistent backup.
ZFS on Linux would be fine with me, if that is part of the solution.
