Time Capsule backing up too much?

I have recently set up a 2TB Time Capsule to back up a 1TB iMac which contains appoximarly 660GB of data and the initial wireless back-up took some 36 hours.

 

As both Time Machine and Time Capsule are new to me, I've been keeping the Time Machine preference panel open to see what is going on (I know, I know, little things amuse tiny minds) and am very surprised to see that each hourly back-up purports to be around 9GB - even though I have done very little work during the interim.

 

Indeed, this hourly "incremental" back-up sometimes takes so long that it runs over the default hour so that once one back-up has finished it immediately starts the next one.

 

What is going on?

 

Surely something is wrong somewhere?

 

And, if so, how can I find out just what?

 

Thanks.

    Yes, much too big.

     

    Are you running a windows boot camp or in a VM.. as that files will be changed slightly and is to TM a single huge file.. you should exclude any windows file VM..

     

    Read Pondini.. the super guru of TM.

     

    http://pondini.org/TM/Troubleshooting.html

     

    Load widget as per A1.. staring at the TM graphics will not help you much.. you need the log files.

     

    Then maybe look at D4 which will give further diagnostic options to discover the problem.

    Where is Pondini when you need him??

     

    Did you run a verify on the disk? I would say it is continually backing up files it has already done.. I have no idea why. Or why spotlight is failing but it points to an issue on the disk in the Mac.

     

    Have you upgraded to Lion? Your first post stated SL as OS.. upgrade installs are not IMHO ever a great idea.

     

    If the verify passes then start excluding directories.. especially anything to do with vm.. parallels etc. although to me that should be a single file.. whereas you are backing up heaps of files.

     

    I would be looking for corruption on the disk.. but I have run out of experience. Far more important than knowledge from this point on.
