In my experience, keeping 20-30 snapshots is no problem, if your
disk size follows our recommendation (at least 16 GiB for "/"),
and if you are doing regular semi-cummulative updates (i.e. weekly).

I agree though that for Factory or for smaller "/" partitions
the world looks differently.

In addition, I strongly suggest to install the "btrfsmaintenance"
package and tweak it to your needs and environment: that way you
get balancing and scrubbing regularily, and you can really enjoy(!:-)
