I'm relatively new to macs (last 3 months) and am unsure as to how to go about the following. I'll try and explain as clearly as I can! I hope I have the right forum too...
I have a 1TB external hard drive for my time machine, which has been running for the last 3 months. It was not backing up my other two external HDs (which I have found out to be because they need to me in mac osx journaled format) and so there is 200gig of music software copied onto the drive, and my itunes of 100-odd gig stored on the drive in a sort of 'self backup'.
I am going to be reformatting my 2 other drives so that they can be properly time machine backed up. The copies on the TM drive will then be deleted.
The Time machine drive will then have roughly 430Gig worth of TM backups on the drive. My 1st external HD has 190Gig to back up, and my 2nd external drive has 260 Gig to back up.
This is going to be very close to the total size of the drive... (1TB = 930gig or something...)
The 190gig HD shouldn't get much bigger in size at all so time machine backups will be few and far between, but the 260gig drive most definitely will (iTunes).
Once converted to the right format, when backing up addition HDs (for the first time also), how will time machine cope?
-Will it say, "not enough room" if I am a few gigs short?
-Will it create the back-ups, but the two new ones have no room to actually back up anymore?
-Will it reduce the size of the 400gig backing up my main HD to make room for the new ones?
Am I packing so much into my time machine drive that it is losing the point of the drive itself?
It might also be worth mentioning that my TM most definitely has back ups of my itunes from before I moved it to an external drive. Is there a way of just deleting the itunes part of my time machine backups? Hopefully that should save me 50+gig...
Thanks for the help
