We tested VEEAM and Acronis.

When I was looking at Veeam, it had its own strengths. How they back up data is different, but they also have a very strong package.

There are other providers for the same type of service, but Barracuda has a good reputation. Sometimes we just upsell to people who already have Barracuda Email Secure Gateway. If you add the backup product, you managing it from within the same console so it's much easier than going with another solution.
