how long does time machine backup for over 500 gb take

im amazed that it takes the long to transfer all the crap from my iMac to 2 tb hard drive.

I bought a new 27 inch iMac 5k to replace my late 2012 21.5 iMac. it has a 1tb HDD and its used 747GB of it. so I thought it'll be few hours for the whole thing to be done, but no... after 24 hours, she's done 60GB only out of 767GB. ***>???? is there any faster way???

A 500 GB backup may take a few hours (maybe up to 10, give or take). If it's a USB connected drive, it may take longer. I would figure the estimate will eventually adjust properly; just let it run.

I am a getting a similar problem, which in my case is not an estimate. Time Machine is really super SLOW. Time Machine told me that the backup needed to be rebulit. It is around 600GB. So I decided to start the new backup yesterday night at 11PM, assuming that overnight should be able to finish. After 12 Hours it only backed up 9GB!! It says that it will need another 22 DAYS !!!

I have OX Mountain Lion 10.8.2. I am backing up over WiFi g/n (in the same way I have been doing for the last 2 years). I have read in a cNET forum that after 10.7.5 version of MAC OSX Time Machine had problems with Spotlight, and that I needed to change something in Spotlight. Please advice what I need to do to signigicantly improve the performance of Time Machine.

WiFi is the least reliable and slowest connection method you could have chosen, try another method, any othet method is faster.

No.
