Even though we backup your data on our

end...you should never trust having all your

data in only one location.  The primary purpose

of this service, and most others like it, is to be

an offsite backup "copy" of your data.  Even

though we can serve as a storage medium to

facilitate access to your data from anywhere,

it is still recommended that you keep a copy 

of your data somewhere else as well.  My

personal strategy is to make a backup copy

of my files onto a secondary local drive...then

using an automated method of some sort,

occasionally sync that secondary drive offsite.

This method works best because it allows you

to quickly restore files without having to wait

for them to download when you need them, 

and your files are still safely offsite in the

event of a home disaster.
