"Everything Else" takes more than 120GB. Can I manually delete old and unused backups from the disk?

Initially I had my backups on the filesystem but a few days ago I set them up with Backblaze (I also clicked "Cleanup Backup" before switching, thinking to free up disk space).

Is it normal that "Everything else" takes 120+GB of space?

By using a few times du -shx * | sort -rh | head -10 starting from root, I found out that the biggest "offenders" outside of the yellowtent home folder are:

• var/lib/docker/volumes/ 57G
• var/lib/docker/overlay2 7.7G
• var/backups 85G
• var/lib 66G

I assume volumes, overlay2, and lib are all needed or my server will probably die.

But in backups I have four folders with old dates in the format YYYY-MM-DD-HHMMSS-XXX which count for >99% of those 85G.

So my real question is: is it safe to remove them with a simple rm -rf?

@stefano Cloudron will not touch the backups in the old backup storage when you change storage. So if you made at least one successful full backup afterwards to backblaze, it is safe to purge the old backup data on the disk itself.

@nebulon Thanks for confirming!
