Speaking of this, does anyone know about any local backups for Linux with a nice GUI? I turned into a GNOMie and don't want to spend time with commandline options to figure it out. I tried APTIK but it flat out didn't work.
I've been using BackInTime (https://wiki.ubuntuusers.de/Back_In_Time/) since 6 years and happy with it.
- it's using rsync and hardlinks, the files on the backupdrive are just normal files
- it got "smart delete" of old backups (e.g. keep 1 backup per year older 1 year, 1 per month older 1 month and 1 per week older 1 week)
- starts an backup automatic in background if you attach the external drive (with udev, if you want it)
- has a nice simple ui (i like it)
It probably isn't quite what you are looking for, but have you ever tried Syncthing? It doesn't have enough features to be an actual backup solution, but it is nice if you just want another copy of your files somewhere else
I’ve been using Deja Dupe for 4 years now for a local backup on my NAS. It’s extremely slow though, and I’d prefer fs level like ZFS or even btrfs at this point.
