I've worked out another way to help with the first backup using Time Machine / Time Capsule. My logic is like this...
-The first backup backs up everything. On a BIG hard drive, that's a lot of data.
-But the first backup actually need-not backup everything.
So, tell Time Machine to backup less, the first time around. Go to Time Machine (within System Preferences), then click on Options...
Add almost everything to the 'not backup' list. Leave, say one folder such as "Library". You'll get a warning dialogue about whether you want to skip system files etc. I'd suggest just leaving those included.
Once you've done that, the next backup should run soon after. It may still backup 6-10 GB (depending what is left on your HD to backup). But that sure beats the 100 GB or so that's probably actually on your HD.
Now, let Time Machine / Time Capsule backup that full selection first. Don't interrupt it (leave your computer on + in range).
Once that's done successfully and completely, go back into the Time Machine preferences, and take off some of those extra 'do not back up' areas off the list. Ultimately, you want to backup just about everything (including Apps, System, Users etc.). Consider only de-selecting a few areas at a time, so that you can get each subsequent backup done OK, without interruption.
The subsequent backups shouldn't take nearly as long as if you did the whole HD in one hit.
Once you've removed all the extra items from your "do not back up" list, your backups will then run across the whole HD as normal, on a regular basis .
Hope that helps speed up someone else's long Time Capsule backups!
i like this plan but hit a bump in the road:
i had already started a 100 GB backup session.
perhaps ill-advised, i stopped the backup and excluded just about everything.
upon restarting time machine, i see that it now wants to back up 75 GB.
if i run out of time (just about to go out of town) and have to interrupt it again, i'm toying with the idea of deleting the sparse image and starting over upon my return.
