i'm curious what everyone is using for their client-side backups. We currently have about 300 clients, with an 80/20 split between desktops and laptops, respectively, running windows XP, upgrading to Win7 over the next year. Currently we backup users' desktops and app data folders, with Laptop users also getting their My Documents backed up.

Currently, we use Backup Exec's DLO option. If works, but the thing hasn't really been updated in years, and I find it hard to believe that nothing better has come along.

Some of the options that we'd be looking for:

* IT management of folders that are backed up
* Differential / block level backups (don't send me the whole file, just the changes)
* Backup over the internet via SSL (no VPN)
