OK, here's the latest version of progbackup.sh in all its gory glory
Changes since the previous version...
1) A bit more error checking, for instance warning that you really don't want to think about running the script if the box is going into standby in a while
2) Some error checking still missing - I've had the webserver go away when testing but that isn't checked for
3) The sidecar files are now copied across and are amended to reflect the new location and the lack of encryption
4) Despite (3), the series file is not being copied over - that might be useful if the files are restored to a Humax hard drive, but they're not copied for the moment.
It should be totally safe to run as it doesn't suggest overwriting the original files, but if you run this and your gerbil explodes, blame the gods of shell scripting.
Any thoughts/comments and suggestions are appreciated as always.

The first run would be a bugger but after that it would just be on new recordings. Might need to watch out for power offs while it's working though?...
