Hi,

In the morning, I boot up my Mac. I run it for 2 hours then I'm off to Panera. I usually eject my external HD's before I put the Mac to sleep. Can I do the same with the HD that houses Time Machine (TM) backup??? I don't want to screw TM up.

Thanks.

Frank
 
Yes, if you eject the TM disk or don't have it on or connected, TM will just wait until the disk is available again to do the next backup.

I am very impressed with TM.
 
you dont need to do anything! thats the beauty of time machine :) when you eject your external disk time machine just waits until you re attach or mount the disk then it starts where it left off. just leave time machine on in system preferences and eject your external disk. then when you get home attach it or remount it and time machine will start the backup straight away. since you did nothing on the imac while you were gone the backup will be instant.
 
Sorry, TM is connected to my MacBook Pro that goes with me. The TM external HD stays at home. Does that change anything??

then your macbook pro tracks changes to files while your away with a special daemon that makes "hard links". when you get home and connect the external time machine backs up the changes to these files by reading the hard links... just beautiful isn't it! [crawls under desk and cries]

I have a MBP. Can you explain that again? Thanks!!

Bill.....:confused:
 
assuming youve done your first initial big time machine backup, every time you disconnect your external drive from your macbook pro (take it to uni, work whatever) a special "daemon" tracks changes that youve made to files and makes "hard-links". when you reconnect your external drive time machine reads the "hard-links" and makes changes to your last backed up files. if its a new file it backs up the whole thing. see this for more info http://www.apple.com/macosx/features/timemachine.html
