i use time machine as well, works great for me. SuperDuper creates an image that you can restore from, copy files from or boot from. once you've formatted the drive properly, it's dead simple.
I'm battling with keeping my FireWire external time machine disk and a couple of others to stay mounted when the system sleeps. Even a USB 3 ssd gets a warning on wake. Time machine it's self is o.k. It's the external drive behaviour that's annoying. Next step will be a thunderbolt dock and string them off that, I think that'll keep the external busses powered up when the computer goes to 'sleep' (which it really isn't these days).
Tools of my trade - deploy a good proper NAS drive - I have tried various - avoid buffalo, but I love Synology - multi macs backing up to a single nas, set how much space is allocated to each.
Laptops backup over wifi (decent wifi router needed (draytek all the way for me). Mac mini backup over Ethernet.
The problem with TM is the constant stalled backups. ('preparing backup') This seems to happen with every other backup. So you think you're getting hourly backups, but when you check you find there hasn't been a backup for a week.
I need something reliable that can be trusted to backup properly and regularly and, if not, at least to let me know.

you can retrieve any individual file from the image SD creates just as you can with Time Machine. it looks exactly like the HD on your mac in Finder.
what it won't do is provide a selection of the desired files from a number of time points, just the last back up. back ups are incremental though, so it's not cloning an entirely new image each time.
It does a clone backup or you can select what you want, can be set to do it automatically, in the background at regular intervals, and saves any overwritten files in a "safety" folder so you can retrieve them later. The "safety" folders are created one for each instance of a backup so you have an time machine like ability to find previous vesions.
It'll also backup up to a network drive or any directly attached storage.
I have it set to do 2 backups a day of the same disk - one to an attached usb stick for all documents and one complete clone to a network drive. Does it all in the backfround.
