Backup is the name of my Game!
It's extremely important for all users to have an organised backup system!
I backup all my stuff from my primary HD onto a secondary HD every night with the click of one button and whenever I can be bothered to CDRW. My mail, IE Favourites, Smart FTP addresses, Music, EMU files, software - you name it. All backed up within a few seconds every night.
The software I use for this is called TaskZip. After the initial backup, it only updates new files or files that have been changed. Just set it up, click one button and 10 secs later you've got a complete up-to-date backup every day!
Should one of the HD's fail, I'll have no problems.
Should both fail (extremely unlikely) I'll resort to my fairly recent CDRW's!
For emulation, I have 4 EMU CDRW's - one for console/arcade ROMS, the other for computer disks/tapes/carts, one for holding Amiga Archived LHA/zip files of software and the last for my WinUAE harddrives - a 635MB HDF file and wb1.3 directory.
Yep, "I'm prepared".
