When listening to a Microsoft speaker on the subject of VSS a few months ago, I realised quickly how little I understood about the subject … and I consider myself pretty well informed. Who better to learn from about the internals of backup than a company that does backup for a living. Queue Altaro and the first on their series on VSS Crash-Consistent vs. Application-Consistent VSS Backups.
Unfortunately, if disaster does strike, there are often more questions than answers. Planning ahead is critical, and that involves knowing what sort of backup you need and if your backup application can provide it.
