> I had scheduled snapshots for my /home at one point but since it's a very actively used directory (downloading isos, games then deleting them) I had similar problems to yours.
What kind of schedule was it? I feel like the low-impact alternative to no snapshots at all is daily snapshots for half a week to a week, and maybe some n-hourly snapshots that last a day or two. Which I would not expect to use up very much space.
It was very frequent (around every 5 minutes) because what I was trying to get was a failsafe in case I delete or otherwise mess up a file I was currently working on. It happened exactly once since I disabled snapshots of /home and I was able to recover it from the terminal's scrollback buffer of all places. :)
As far as I know btrfs does get slower as the number of snapshots increase. Not sure about zfs in that regard. Your plan does sound sensible. I have a feeling you could make the snapshots even more frequent without any ill effects.
