I backup my home using backintime once a week to an external USB drive.
My "system" (a.k.a. "/" a.k.a. "root") gets snapshotted daily by timeshift to my other internal "data" HDD.
So i always have my personal stuff (-> home) on my external drive. The snapshots of my system are still stored on my laptop (not external like my home), but at least on another drive (system on ssd -> snapshot to hdd). So i am pretty relaxed doing system upgrades like this weekend (gnome stack upgrade) 😁
