Snapshots are not really snapshots in the traditional sense of the word,
when you use Box. A snapshot just means that you decided to sync your
disk to the backup store at a given time. So, you don't really have a
physical set of files that are snapshotted, but rather a set of initial
files, and patches applied to those files reflecting the changes between
snapshots (it's a little more complicated than that, but that's the
basic gist of it).
The way that Box works, the best way (IMHO) is to figure out the size of
the backup set that you want, and then adjust your storage allocation to
So, if you find that 45 days of backups takes up ~30GB of data, I would
issue the following command:
bbstoreaccounts setlimit XXXXX 30G 31G
to set your limit to 30G with a 1G buffer.
I can see the benefit of supporting 'x days old' as a way to decide what
gets deleted from the store. It might have to be done in conjunction
with some storage size, to avoid running out of disk space.
