We just got Cohesity. I was working with a server engineer on what this means to SQL Server.
I had a TEST SQL Server 2014 that we did some tests on. Cohesity was able to, behind the scenes, do a byte by byte backup of the actual server and then we shut it completely down and brought it up in its entirety in the Cohesity VM Host environment. SQL Server started and appeared OK and the application databases were accessible. However, I then restored all of the databases with our other SQL Server backup toolset. Integrity checks ran just fine. I wish I would have thought to run integrity checks before I restored the databases though. Our next test was to utilize the Cohesity supplied SQL Server backup/restore process. Something wasn't working correctly though because it would run the backups and I saw them complete in the SQL Server logs but the tool did not see the backups so we could not restore them. We were going to call Cohesity support but got working on other things and just never got back to it.
