Easy to install on the server and on the clients. Excellent documentation of Server Install guidelines for all environments.
The restoration process from the cloud can take quite some time
Backing up dispersed client base with many GB of remote data, as well as data on file servers pretty much on autopilot, with occasional monitoring. I love being able to download simple file restores, push a restore to a client machine, or do complete restores to a client when a hard drive or system fails.
