I have been going through a great deal of change over the past 3 months. So while I am in flux I decided to minimize my use of local storage. I have started using Amazon S3 via Jungle Disk on my MacBook Pro. Storage in the cloud is very appealing to me, accessible from anywhere, anytime makes my life easier. Managing USB drives and DVDs is a pain in the neck.
I know that S3 is not perfect but it sure is nice so far. Jungle Disk appears as a mounted drive in Finder and I just drag the files into the drive. In the back ground Jungle disk uploads my files to S3 using my account. I have yet to do a back-up but that is on my list of things to do. The only think that does suck is the fact that my cable provider tightly limits upload bandwidth. So if you have a second try Amazon S3 and Jungle Disk.
