Pest, that's what I was worried about. Not a big deal - the local drive has
storage for ~150 hours of SD, which has always proven sufficient up until
now. I'll just have to work out an extra bit of script to notify me (perhaps
by email) when the NAS is full, with the local drive taking up the slack
until I get around to clearing some space. No problem, since the archive
script will have to check for free space before attempting to move anything
