On a Windows Small Business Server 2011, I have redirected the shadow copies for all volumes to a single, dedicated volume. This volume contains no other data; the only folder is System Volume Information.
Is it necessary to back up this folder for disaster recovery purposes?
I understand that the System State backup as well as Exchange and other services are backed up using VSS and that VSS writes to the System Volume Information folder, but it's not clear to me if that data is also written to the backup media separately as part of the VSS operation (that is, the SVI is used as a staging area) or if the SVI folder must be backed up after the VSS backup using simple file-based backup techniques.
