[OSX-Users] Re: Mac disk encryption

[Hugh Glaser]

I had no such offers (on my MacBook Air or on my very old MacBook Pro) - they still have it turned off.

I have decided not to use FileVault.
I looked into it, and (my understanding is) that for encrypted disks, Time Machine can only do a full disk recovery, not individual files.
It is very hard to find anywhere that talks about this (I have just tried again); nothing easy via google, but I got this just now:
http://www.appleexaminer.com/Networking/TimeMachineFileVault/TimeMachineFileVault.html
But maybe that was only File Vault, not File Vault 2?

It would be an absolute pain to have to have to recover the whole disk somewhere to get at a file I accidentally erased.
In fact, what is the point of Time Machine working in its nice way, if all I can do is recover the whole disk?

So, the usual tension between security and convenience leans in favour of convenience in this case - do I really have stuff that needs to be kept that much more secure (than the way it is already in KeyChain etc.), on the off chance I lose my laptop or it gets stolen, AND the people who get it want to misuse the data AND they are able to profit from it or damage me because of it?

I decided the answer was no.
Of course, where business use requires it, I can keep another user that has encryption turned on - it is per user.
