It is a crowded space that is only getting more crowded. The majors that you are going to see out there are Iron Mountain, Symantec, EMC and IBM. There are some software companies that have gotten into this space in a big way too, mainly EVault which was just acquired by Seagate, Asigra, which has heavy partnerships with AT&T and Hewlett Packard and other startups like Digi-Data and Carbonite.
So, if you look at the market, you will see quite a few companies that are in the startup phase that are leveraging software from companies like Asigra. So it is an interesting space, there is a lot of acquisition happening, with the biggest and most industry-shaking probably being the EMC acquisition of Berkeley Data Systems, in which the Mozy service product line was acquired in 2007 and has been focused out on a consumer and even enterprise customer basis.
