Very Robust, Comprehensive Solution
I used this for a few years in a previous position. We initially implemented the 3.x version when we started to have problems with our backups when the content databases exceeded 40Gb. They system was easy to implement, and I was up and running within an hour or two.
This was one of the first to offer Item Level backup capabilities. I really like the options offered for granularity, frequency, etc.
This product served me very well. We continued our upgrades through the 4.x and into the current version. We later added additional modules like the archiving and disaster recovery that are now part of the base product.
