hi,what files should i be backing up??
is there any other way of doing it but not using a lot of discs and what discs are best?(DVD-R,DVD-RW,ram etc etc)
For backing stuff up, I would just use DVD-R's because they're cheaper than RW's, unless you're backing up small files every single day, then just keep adding them to the same DVD-RW disc.
You should backup any files that are critical to you. For instance, I backup all my school work on a weekly basis, along with all my other documents, and web design files.
I do a full backup of mp3's, applications, games, photos, about every month.
Should I backup operating system files? I don't think you should, unless there's settings or saved features you want to keep. (like log files for chats for example)
Do you have a lot of disc expense? I do my backups to a external usb 2.0 hard disk, and then back it up on another hard drive on my server. I only actually do complete backups to DVD-R's about twice a year.
