As you probably have heard that AvePoint's Doc Ave V1.0 (upgraded 1.5)
provides a document level backup solution for SPS. By using new MS APIs,
this is only one able to backup not only workspaces also dashboard and
webparts (system folder).

It fully supports both full backup and incremental backup, scheduling,
document searching, folder filtering and scripting. In addition, we offer
the best price on the market, only $499/license.

It's easy to use just like a personal software. You just need to take a
couple of minutes to learn how to use it from online demo:
