There is myth_archive_job.pl (not to be confused with MythArchive).
In the contrib directory. Read the script, it is pretty self-
This simply allows you to easily move files to alternate storage,
which could be an NFS-mounted directory or anything else. It simply
replaces the file with a symlink so Myth still sees the file.
It's a nice script, checks for available space before moving and can
check several possible directories to find one with enough space. It
also lets you specify how much room to leave on the storage directories.
If you have spare space on another Linux machine I'd just export a
directory via NFS and use that for a directory for myth_archive_job
This assumes of course that your network can take the load. SD over
hardwire is no problem but HD over a wireless link would probably be
