Just my hunble opinion, with a few facts mixed in........
As a stand alone file and folder backup utility, BESR is not worth spending good money on. I've worked with this product since version 1.0. At its inception, this product was intended to be a sector by sector hot imaging utility for entire disks. The logical purpose was then to use the resulting images as a means of disaster recovery.
I applaud the additions such as Restore AnyWare, Cold Imaging from the SRD, and custom SRD creation. However, I think the addition of file and folder backup needs a serious reworking to resemble the functionality of Backup Exec for Windows servers. I'm not saying it has to be excatly the same, but something better than the awkward interface and capabilities of the current offering. Perhaps the difficutly stems from trying to make a sector level copying tool into file and folder backup tool as well. Of course we the end user do not have access to the source code, so we can't see the struggle to pair up complimentary yet sometimes conflicting backup technologies.
