Thanks Eric, that's a really neat way of doing it
Re the space issue, would it be possible to make a back up just once a week instead? (So we are only saving 4 per month) At a guess I'd say simply set the cron to run once a week instead (so it falls on the same day, 1,8,15,29)?
That just seems too simple tho so I'm probably wrong! :lol:
Also, is it ok if I write this up into my guide on back ups (include it with the htaccess site shut-down bit) and post it on my site? I'll credit you of course

I generally write up useful tips like this and store them on pc for personal use, but when I think the guide may help others I post it on one of my sites too as it makes it easier for me to share it with others when I think they may need it.
Any other tips would also be appreciated! (For eg, do you think it would be better to do a mysql dump once a week, and maybe a mysqlhotcopy every 3 days?)
Thanks again for your help, much appreciated!
