originally signed up with a competitor online backup product but was having so many problems with it that I cancelled the subscription in favor of Carbonite. It installed without incident and immediately after install started an online backup up my designated folders. The initial online backup took a number of days to complete but because it happens in background it didn't interfere with my daily routine. Restoring files from the online backup is a snap and I am able to restore previous versions of a file from my online backup dataset. I've had a number of situations when I wanted to go back to a previous version of a file and was easily able to do so from my Carbonite online backup.
There are a few things I recommend you do to ensure a comprehensive online backup strategy:
I like to use an external hard drive as a backup source in addition to doing online backups. While Carbonite is a great online backup solution, an external hard drive is faster than restoring from your online backup. Doing both external hard drive and online backup balances speed with security in the event that both your PC
and external hard drive are lost.
Back up your c:\users\%username% directory to ensure you online backup not only documents but also your favorites, your desktop, and other information about you as a user.
Go with the recommended online backup schedule option. It's best not to second-guess Carbonite's online
I highly recommend Carbonite for safe and secure online backups. Go here for a free trial.
