Backups? How do you "do it"?

I would call it a poll but the options are just to many. The question?

How do YOU do backups? How do you keep track of your chit?

IPS patches? Saved ROMs? Pen and paper?

Of course there is always: "Backups? I don't need no stinking backups! " for those that run commando and carry their balls in a wheelbarrow.

Me personally, if I'm doing map work, or any work with tools (LE, FF3usME, SE, etc) I make backups of the entire ROM after every success. I work on three ROMs at once. Test ROM, most recent backup ROM, and generally a vanilla ROM or slightly stable patched Rom for referance.

For code, either edit or write, I do everything in Excel. If a byte gets changed, it gets sectioned off with its own title bar, offsets added to the side, hex code in the firat five colums, ASM code beside it, then comments beside that. No real backups for this kinda stuff and only a test ROM that gets butchered often. Takes about 5min to grab a fresh ROM, then copy/paste all the edits and back to current.

The purpose of this thread is mostly just my curiosity, but could also be a way for newbies to decide how they want to backup their own projects. So...

How do YOU do it?
