Hi, I've found a thread or two about this before but I never really found the advice I was looking for and now that I'm really considering it I figured I should just make a thread myself. So recently my MacBook Pro (2009) was sent in for repair and they unexpectedly said they needed to replace my Hard Drive. I had no backup whatsoever. I managed to salvage most of my data and files from other locations but it really messed me up. I'm glad they replaced the drive, just wish they didn't need to. Anyway, this got me thinking I really should go ahead and get a Time Machine dedicated drive. I think I'd like to get a network compatible device but don't really want to have to pay the premium for Apple's Time Capsule. I was considering a Seagate drive. I found that I could get a dock that makes a FreeAgent Go a network drive and I could get a FreeAgent Go drive with up to 640GB of storage. I currently have a 160GB internal hard drive but the next time I get a new computer I'm almost sure I'll get one with 250GB of storage so I'd like to base it off the latter. I don't so much want to use it for.... well, it's actual intent. I understand that the cool feature of Time Machine is that it has multiple backups and lets you go back in your digital time line and restore. I don't so much need this. It'd be nice to have a few to go back through just in case but for the most part I really just want to use it to have a backup of all of my data in case something happens to my drive again or I decide to move to a new computer and could use it to restore my data. So if I were to have a 250GB drive to back up using Time Machine to a 640GB external drive, would this be enough storage space? Do I really need the 1TB or is that just for people who want to be able to go back months and months in time? Thanks for any and all help!!
