[SOLVED] How much disk space are my snapshots taking? | Arch Linux Community | Page 1

I use btrfs as my filesystem and I have configured snapper to make automatic snapshots whenever I update my system. These snapshots are sitting in a btrfs subvolume mounted to /.snapshots. I ran df -h /.snapshots to see how much space on my drive those were taking, which eventually returned a 1.7TB figure. That number is obviously absurd given that the btrfs partition is only ~470GB in the first place, of which ~50GB is occupied.

How do I find out the ACTUAL disk space taken by these snapshots?

btrfs filesystem du -s

#

df/du is not reliable for btrfs

sidenote: don't forget to set a limit to the number of snapshots

Thanks. How much would you advise the limit to be?
