[In honor of Backup Exec dropping its Unix support across the board with its Backup Exec 2012 product, I’m going to do a few posts on the Unix market overall. This is part 2, part 1 is here. The basis for the data discussed here is Gartner’s [Market Share Analysis: Operating System Software, Worldwide, 2011 – published on April 25, 2012]]

Before we dive into Unix, a few words about Microsoft and Windows. After we entered the proclaimed “post-PC” era (proclaimed by Apple and all of the VDI – Virtual Desktop Infrastructure – players), you’d have expected overall Microsoft Windows shipments to – in a word – suck. And sure enough, the Microsoft Windows client business grew at only 3.4%. Windows 7 in particular had relatively sluggish uptake. However, Windows Server grew 13.9%. Gartner reported that cloud and virtualization were the drivers for this growth.

IBM was the second largest market share operating system vendor in the world and grew 8.6%. System z, AIX, and System i (iSeries or what used to be called AS/400) contributed – although only System z and AIX actually grew. AIX is doing well and is now the #1 Unix operating system in terms of revenue (displacing HP-UX.) Gartner has a lot more data on this.

I’ve always wondered why more backup vendors don’t support AIX – and in particular, AIX bare metal. AIX is a good operating system and IBM has invested a lot in it – seems short-sighted for all backup vendors to crowd into Windows and VMware and ignore AIX.

(Note: Of these, Unitrends handles backup of Windows, Linux, AIX, HP-UX, Solaris, and iSeries – as well as Netware.)
