If you want to learn a lot about TM, then visit here.

TM backs up hourly for 24 hours, daily for 30 days, and monthly until the backup drive runs out of space after which it will start to delete the oldest backups to make room for the newer ones.

Thanks Kappy and Tech Guy. I'll try and digest that info--it may take awhile!
Just for info, I am using a Lacie d2 500 GB, presently it has used 263 of the 500.
It is presently backed up until January 2010 which must be the date I hooked into Time Machine. I have a 1TB iOmega which I am thinking of using for the back up drive but feel the Lacie may be the better of the two so may leave it on.
Thanks again. Cheers.
