I might do better to simply back up the whole hdd rather than separate os+apps from personal files. My thinking was that the os would be on a separate partition and backed up infrequently so less chance of a backup error making it not bootable. Personal files need daily backup - so more chance of some error but I'd also back them up regularly to optical media. May be my Windows-bred paranoia of backup program reliability. Also I'm not used to GUID and mac os extended journaled. IMO partitions are a good practice for the MFT, NTFS and Windows. Maybe no advantage for macs.
I really wish mac did multisession dvds or ram disks since daily backups to optical media w/ weekly backup to ext hdd is what really worked for me in the past. Keeping an ext hdd connected to my computer puts it at risk for power surge/brown out/knock it over/spill something on it problems and having to plug it in and unplug it daily means I'm more likely to skip backups.
IMO neither mac nor pc provide users w/ adequate backup options by not using optical media to its potential. All those optical burners ought to be useful for more than music/video burning. In 2011 we ought to be able to do reliable, multisession DVD/DVD_DL data backups and have drag & drop to optical media functionality. With winXP & Nero I did have reliable multisession DVD BUs for awhile, but after a lot of updates I also spent a lot of time trying to figure out if a problem was w/ WinXP, Nero or the hardware. RAM disc and packet-writing drag & drop never worked w/ Nero on WinXP.
Time Machine is great for part of a backup plan, but it doesn't give you off-site storage and any hdd can die at any time. Per personal experience, I know limiting my backup to a single ext hdd is inadequate. Optical media proved more reliable than zip disk and I can keep BUs in my security box at the bank. Online storage has capacity and speed limitations, plus I have questions about security and future access.
If I do a whole hdd backup then I ought to do two rotating backups - checking the latest bu's bootability before backing up to the other backup. But w/ daily bu's that'll get old fast. I ought to have the 2 backups on separate ext hdds. I read after I bought it that the little portable ext hdds like my LaCie Rugged tend to have more problems than the larger ext hdds so I probably ought to get a 2nd ext hdd when finances permit. I could keep the Rugged attached to ensure daily backups and use the 2nd ext hdd for weekly, unplug when finished backups. Then if a surge fried both the internal hdd and the Rugged I'd only lose a week at the most.
