My computer's hard drive is 100 GB, so I created a 100 GB partition on my external hard drive for Time Machine, before I really understood how it worked. Of course, I eventually got a message saying it was out of room. If I understand correctly, Time Machine will continue to back up changed files, but it can no longer maintain a complete series. Rather, it will be forced to delete older backups to make room for newer.

Anyway, do you think a 200 GB partition would be big enough? Or does it simply depend on how much work you do on your computer (or how many files you change and how big they are)?

I'm thinking of reformatting my 500 GB external hard drive into five partitions...

100 GB for cloned copy of my hard drive
200 GB for Time Machine
Three other partitions for quickly backing up and/or storing websites, graphics, music and things that take up too much space on my computer.

I still don't see a tremendous need for Time Machine, as I very, very seldom go searching for lost files. However, I suspect there may be occasions when it might come in handy.

    Really depends how much stuff you do, how many files you change each day, how much stuff lands on your computer for a few days then is deleted (for example I have several GB of photos on my Mac for a few days until I do some work on them and drop them on the company server, so I have lots of stuff getting backed up into Time Machine that doesn't even stay on my Mac)... It doesn't hurt to have a backup of them locally in case something goes wrong on the company server...

    So what I'm saying is, it totally depends on what you do with your Mac... I've got a 120GB drive, getting backed up to a 500GB drive, and I figure that gives me a year or two of not having to think about it. Drives are so cheap now you are best to just go a bit bigger for the convenience of letting it backup everything..

    Will Time Machine keep growing until you fill up all available space on the drive?

    I have a 300GB which I use to back up my 120GB MBP, but I also use the remainder of the space to store things I don't want to carry around on my MBP. My Time Machine back up has grown to 2.08GB and I'm afraid it'll keep growing until I don't have space for anything else.

    Is there a way to limit Time Machine's growth?
