Although I've had an Amazon Simple Storage Service account for awhile, I haven't used it. For those of you who aren't familiar with S3, Amazon has opened up their resources for everyday people to use. In this instance, you can use their servers as a place to dump your files online. Currently they charge $0.15 per gigabyte of storage used as well as a fee for the bandwidth to transfer it back and forth.
With this setup, they take care of the administration, backup, redundancy, troubleshooting, and the storage scales to whatever you need automatically. I've been searching for a good backup script so I can backup all the stuff I have running on this web-host, but most of them have been beta to this point or a pain to setup. Today I finally installed Brackup through CPAN, along with all the requisite Perl modules. I've already tested a backup and restore and it seems it will fit my needs well.
