Use snapshot. Free and functions effectivelly like TimeMachine. There's a writeup on how to get it going on older Macs somewhere on the Web. 

Good backup options for Mac pre-TimeMachine
I use ssh on my machine, and have set up a long not-human-friendly passphrase which is saved in my password manager.
What makes me crazy every time is that I cannot paste into the window pictured below. I know the Remember password in my keychain option and use it. Sometimes I have to enter a new one though. Why can't I paste into a password field? We're in the 21th century and password managers have been invented! Apple...

Same thing for the dialog which pops up when plugging in encrypted disks.

And yes, I'd rather write a post on stack exchange than type the passphrase even once.



Some updates:


I found out how i can circumvent the stupid dialog: just use ssh-add ~/.ssh/id_rsa, and then I can paste the passphrase into the terminal.
However, it does not work with my passphrase... using openssl rsa -text -in id_rsa I can decrypt the key without problems, but the same phrase does not get accepted by OSX's ssh-agent. My Key is encrytped using pkcs8 (read here), mattmcmanus seems to be right...
using ssh-add still not fixes the thing for encrypted disks, and my curiosity for why apple would do such something.
I answered the question regarding PKCS#8 below.
