mmm Aqua do you have your lair in an extinct volcano? spose it's a little OTT lol
anyway I have used a program called careful backup before which was excellent, it's got a 30 day free trial and then it's about $35 but it is good, you can create different groups of files to backup etc... you just set the files you want to back up, where you want them stored and then save it, when you open the program up you just dbleclick on your group and it's away on it's own..done !
I
am using "backup Now! v 3" which is ok but doesnt seem as intuitive as the careful backup one..but it does the job well and compression is good too,
to be honest I make sure I upload all my sites images etc to the relevant site regularly even if I
am not using them at present so should the worst happen I can Download the full site folder...with web images, png, photoshop files etc too rather than just finished uneditable jpeg/gifs.
you only get burned once with backups, it's a steep learning curve..!!
