Amazon Just Made it Harder
I downloaded and installed Mozy yesterday. Mozy gives users 2GB of storage to backup their files for free. You can upgrade to the unlimited version of Mozy for $4.95 per month. I really like the application and the features of it. It is a full service backup tool.
However, Amazon offers online storage as part of their S3 web services. The way they charge is a little different. They charge a monthly fee for the amount of space you are taking up on their servers as well as a monthly fee for data transfer. With two fees compared to Mozy’s one, you would think Mozy would be the cheaper alternative. Except that Amazon is dirt cheap. They charge $0.15 per GB of space used and, with their lower price going into effect as of June 1st, charge only $0.10 per GB uploaded (there is a tiered fee for downloading data that ranges from $0.13 to $0.18 per GB). That means for a backup solution, you’re costs will be front loaded but month over month costs should be cheaper. For $4.95 per month, you can house 33GB of data a month – assuming no uploading or downloading. And since you only pay for what you use, you may not have need to backup 33GB – making it cheaper than Mozy in the long run.
This is unless you have more than 33GB of data. If you have more than that, use Mozy. And if you have less than 2GB of data, use Mozy (it’s free). So, the Amazon sweet spot is between 2GB and 33GB. This is what’s making it hard. I’m in the Amazon sweet spot. But I don’t want to have to change my backup plan when I reach 33GB. Arg!
As for the software, for Amazon I’m using Jungle Disk. The nice thing about Jungle Disk is it lets you not only run incremental backups on change files, but it lets you mount the S3 service as a drive on your Mac.
