Wow, what a great thread to remind us all of this!
For a few years I have been making sure I back up everything important on my computer every month. Each month I copy all my new/altered files since my last backup onto a set of five DVD-RW discs. On the sixth month I backup everything onto a set of DVDs or an external hard drive.
However, I have been trying to change my method. My brother has a NAS set up at his house and I am trying to FTP into it and update everything. I really would like some suggestions for a program that could do that for me automatically.
However, it does occur to me that I have done nothing to back up my site, and while I do still have all the comic pages, I don't have any backup arranged for comments and such. I should look into that...
ALSO, the actual files from which I create my pages are all duplicated into another folder on my computer. This is so that if I ever do something stupid like save the file after I merge all the layers or delete certain portions I still have a copy I can fall back on. Thank goodness I have this, too. I went back last week to look at one of my old pages and I found that I had done exactly that; I had deleted a whole quarter of the page while making the final composite that was displayed online. Thank goodness I had that older backup.
