What is meant by back up is the complete system. Everything included. Not just text files or your favorite pics or tunes. But programs, operating systems, preferences, etc. Companies, major or minor, programmers, ad agencies, media publications, etc., do it all the time. Drive crashes, load up from the backup and you're set to go in minutes.
Everytime I walk out the door with my laptop, I take a copy of every important thing that I did since the last scheduled back up and put it on a key. Key is in my pocket and if the data is extremely sensitive I push a copy on to an external server. But they are still copies. The back up is secured much tighter. Offsite. Under lock and key. Ready to download in the god-forbidden case that I trip over my machine in the pub and have to replace the hard drive or simply retrieve any files that I may inadvertantly deleted.
Upside, if my drive crashes and I have to reinstall, it is a lot simpler and faster to get back to work.
So what is missing? Besides the fact that I am only backing up incrementally now, the chances are that I don't really have a current bootable drive. Sure it has all the old stuff, but to make it work, I would still have to install an OS before I upload from the backup.
From our understanding of Time Machine, it appears that if your drive dies, you get it replaced and you are right back to where you were. Obvious if you have Time Machine set to only work at midnight, you will have lost any input that you made since.
So, if I don't have to install a new system first, update drivers, install programs, set passwords and/or update preferences, a few minutes after hooking up the backup, I am on my way back to the pub, while a poor undergrad sweats all night reallizing the he may still have to retype his thesis because I also fell on top of his backpack when I tripped over mine. I of course could help him, but hey, I am not a student.
In closing, Apple again has done its homework. Research. Innovation. Service. Support.
You could say, there just may be no better backup to have.
Well, you are overdoing it. No police are involved. This is a computer, not a shooting.
In fact, for years, people were advised to just backup their data, and possibly, their passwords, and such. With OS X the Home folder.
I do back up everything. But, you are going for the most disasterous route when you talk about a crash. It is rarely that bad. Many times over the years I've had a partition go down with the other ones still working fine. That's the normal situation. I'm not the only one.
If we are talking convenience, then everything should always be backed up.
If you have been reading my other posts, not just the ones to you, you will see what I'm recommending. But how many people will do the completely correct thing? Do you?
For a business, a complete backup is required. For most users, it would be very nice to do so.
In a college situation, if you can back up to their network, then by all means, do so.
But you seem to be ignoring my points here, even though you seemed to be startled when I mentioned external drives not being carried around. That is, the very fact that I would even mention them. The fact that no one is going to carry one around, unless they are completely anal, means that there will be some long times between that network backup.
Please don't try to tell us that college students are going to run to the nearest node and backup. You know they aren't.
If they aren't hurrying to their next class, they are hurrying to the pub for their next beer. Backup will just have to wait.
Having that other partition to use meanwhile is a good idea, just as long as they don't make it their only idea.
If you think I'm ADVOCATING that, you are sorely mistaken.
