Q: Time Machine slow, bogging down computer.
I am having problems with Time Machine backups taking forever and, at the same time, bogging down my computer to the point I cannot use it.
For example, a 70MB backup yesterday took almost 5 hours. a 500MB one today is on hour 5 and still going. I have it set to back up while I'm at work (it's my home computer) but when I get home and it's still going I cannot use my computer at all without cancelling the backup due to lag, spinning beachballs, and apps crashing.
The hard drive it's backing up to is a 1TB Iomega drive connected via USB with 500 gigs of free space currently. I've got a 2011 MacBook Pro running 10.8.5, 500gig hard drive with 70 gigs free. I have run backups with my normal apps running and with virtually all apps quit, including Finder and Dropbox, which doesn't seem to effect the time spent backing up. I do not have any virus scanners running. I've tried different USB cables in case it's a faulty cable. I have gone through Pondini's guide dozens of times, nothing's helped.
Do you guys have any more suggestions? I dream of the days long past where Time Machine would work in the background and I'd never notice it. Backing up is now an all-day ordeal with nothing else able to happen in the meantime. I'd like it to do it's hourly back-ups and get away from using TImeMachineEditor to only do daily back-ups, but I can't have my computer unusable every time it tries to back up.
Also, somewhat related; I tried to update my back-up drive to a 2TB Western Digital and to a 1.5TB partition on a 3TB Western Digital drive but was unable to get Time Machine to complete a back-up to either drive; it kept crashing and burning at various stages. I had followed Pondini's guide to the letter with formatting them yet never got anywhere. That's why I'm using my older, smaller drive; it's the only one I can successfully get to back up. Any thoughts on that?

Alright. Cleared out everything I could. Time Machine isn't going any faster, however, my computer isn't bogging down while it works, so vast improvement.
What would be my next step? Take a look at the hard drive for potential instability? What can i do beyond a verify disk?
Improvements are good. You can try some of these things...
Boot into your recovery drive and repair your startup disk. Repair disk permissions too.
Try to backup again to one of those newer drives and see what happens.
Create a new directory on your Time Machine drive and try to copy about 100 MB into it. How long does it take? Delete that test directory when you are done.
Print out your latest EtreCheck results.
It is beginning to look like a failing startup drive. On a MacBook Pro, those are quick and easy to swap out (not counting restoring from backup, of course).
