So, I tried a search for this but didn't really find any details or threads. I did a nice TM backup on a new MBP, came to about 40GB total, I excluded folders like my itunes library and desktop, where I store a bunch of installers and such. after a week, I did it again, and it added about 1GB. Then, after another week, just internet use, a BIT of email and such, I did another backup and it added 8GB to the total, to a total now of 49GB? WHAT THE HECK was in the newest 8GB? Is that another new snapshot or something, since I CERTAINLY didn't add 8GB of stuff? I cannot imagine why it would increase so much, is this type of thing normal? Will it simply add this much every couple of weeks, if so I am going to need a bigger boat!
