After nearly losing my A1200 config and files yesterday through a failing HDD, I've started wondering how often you back up, and how?
I last backed up in June last year and was able to recover the corrupted .prefs files and the Xen font I use for the desktop; nothing too serious this time fortunately. I use lha to make an uncompressed archive to an SD card. It could have been a lot worse.
I'm also replacing my 3.5" HDD with a 4GB CF adapter preformatted with PFS from AmigaKit.
