I've just tried removing the cache directory, and just backed up
again. Unfortunately the cache directory returned at the same size.

This depends. I don't simply run 1 command for my backups and be done,
it's several and they are all stored in different locations within my
Amazon S3 bucket. Right now one of my largest domains that I'm backing
up consists of 45 100MB vol files, with incrementals varying between <
1KB to a few 100MB vol files (depending on how much data was added of
course)

Unfortunately for those with our heads in the cloud, 1TB would cost an
arm and a leg.

I've just noticed something strange, though, whilst running the
command manually instead of via cron I get the following output which
would imply it can not remove the older files, which would be
increasing my metadata size, correct?

I have my scripts to create a full back up every month, and to remove
older files after 6 months. As you can see, May and June should be
deleted.

Kind regards
