For personal or small business use, Amazon S3 is
a useful as well. I am
US for few months and all my data is accessible
here since it was backed
on S3. There are lots of tools for Linux, Windows
and Even mobile that
sync a filesystem with S3 buckets. And it has an
open API too.
This may be a viable solution for small data sets. Besides, 'Net
connectivity speeds is also a factor.
Can you give a ball park idea of how much data you are backing up in the
Data is not large, its around 20 GB. Mostly photos/videos so cant compress
it. Net connectivity is definitely as issue. In Mumbai it takes 4 - 5 days
to sync 4 GB worth of Pics/Videos once I empty Memory card form camera to
PC. Have scheduled sync to run only in time window of 12 AM to 6 AM.
It costs 200 - 400 per month. That includes hours of VMs on EC2 that I
create to try out that things that require 3 - 4 GB download or higher.
