Might be offtopic, but i think when looking for alternatives the options should be broad, questioning the category of the app, not just clones and forks.

If you are considering migrating away from github, don't just consider gitlab and gitea, consider just git, and so on..

If you are considering migrating away from rsync, consider dd. You need to configure the folders you want to backup as mountable partitions or disks, but it does byte for byte copies instead of 100kloc fuckery.
