Matthew F. Dennis commented on CASSANDRA-3453:
----------------------------------------------
1) It is easier to backup/copy all your snapshots for all keyspaces if they are
in one place instead of having to iterate over all the keyspace directories
looking for the snapshot directories.
2) it is safer when deleting snapshots (less chance of scripts/admins
accidentally deleting the keyspace instead of all the snapshots. (e.g. rm -rf
/some/path/$ksname/snapshots/* where $ksname ends up a blank space because of a
script bug)
besides, checking a setting isn't very complex code wise ;)

> cassandra.yaml really needs a config option for a snapshot directory. by
> default it should be a peer folder with saved_caches, commitlog and data.
> assuming the value of that setting is /some/path/snapshot_dir then snapshots
> would go into: /some/path/snapshot_dir/snapshot_name/keyspace_name/
> this makes automation, particularly around backups, much easier and gives
> more control to ops
