Over at Backup Central, Curtis Preston has written a couple of excellent blog posts to do with VSS.
The first, What is Windows VSS and why should you care? is an excellent overview of how the VSS process works within Windows. Even if you’ve been using VSS within your environment, if you’re not quite sure how it works, this is a great piece to read.
The second delves into issues relating to VMware VCB’s (in)ability to perform consistent application backups – i.e., via VSS for say, an Exchange or Microsoft SQL guest. Titled Hyper-V ahead of VMware in the Backup Race, it’s a justifiable kick in the pants to VMware, and a pointed warning regarding VMware/VCB backups of applications.
(These two articles, Curtis mentions, came about from some posts by Scott Waterhouse on The Backup Blog, which talked about vSphere backups.)
