I suspect that it wildly varies based on user.
If you use video streaming from, say, YouTube and TikTok heavily, and you do so outside of WiFi networks, I bet that you can burn through a lot of data pretty quickly.
Another user could be sitting on Lemmy or whatever all day every day and just not use much data.












It’s not so much text or binary. It’s because a normal backup program that just treats a live database file as a file to back up is liable to have the DBMS software write to the database while it’s being backed up, resulting in a backed-up file that’s a mix of old and new versions, and may be corrupt.
Either:
or:
In general, if this is a concern, I’d tend to favor #2 as an option, because it’s an all-in-one solution that deals with all of the problems of files changing while being backed up: DBMSes are just a particularly thorny example of that.
Full disclosure: I mostly use ext4 myself, rather than btrfs. But I also don’t run live DBMSes.
