A few months ago I had two RAID NAS storage devices fail on me within two days of each other. These two devices comprised 100% of my backup capability, which got me thinking about some off-site alternatives for some of my data. After a lot of research, I decided to go with Amazon’s S3 service which provides reliable and very cheap online storage and JungleDisk (which gives me a nice interface to S3 with custom encryption of files before they are uploaded to Amazon).
After a few months of use, I must say that I am very impressed. The Amazon storage is costing me about $1.00 per month and the lifetime license for JungleDisk is $25.00.
I am not uploading things like pictures or music yet, but I just may do an annual load of our photo library just to be safe. If you are looking for a cheap and reliable offsite backup, it is worth taking a look at this combined solution.
