I've used dd successfully. I backup my home system nightly, but only my home partition. I can easily rebuild. However, rather than use dd, something like rsync will be a bit quicker. What I would do is to make up the mirror disk, with LILO and everything installed and tested. Once that is done, create a rescue floppy. Then use rsync with the desired options to pick up any changes. There are some cases where you can render the mirror unbootable, such as changing the kernel and not running LILO. But, if you keep the boot floppy, you really don't need to worry. There is nothing positional in the Unix/Linux system. The only thing you need to be concerned about is when you upgrade the kernel, make sure you've run LILO. But, a bootable floppy gives you a back door. Certainly RAID provides you with a degree of protection, especially in a high volume system. In a low volume system, a periodic backup should suffice. A backup to a removable device is preferable since online storage is subject to environmental factors. A removed device is ostensably not subject to a power surge resulting from a lightning strike.
