Mozy Pro was our one and only end-user backup client at my previous employer. It was used across the entire organization, including high-level executives all the way to the C-level. We used IT to backup users' critical files, although we did not use it to perform full backups of machines. It primary was used to backup profile data, such as My Documents, My Pictures, Favorites, Desktop, Downloads, etc. Mozy Pro does an excellent job of this. It is also very easy to administer from the web portal. It makes adding new users, restoring backups or downloading them very easy, for both admins and end-users. We were also very impressed with how easy it was to update policies and push those to users. It worked very well, and we rarely had to engage support for anything.
