Do I need to backup Shadow Copy Components?

[Jim_Barr]

The answer to this may be obvious, but I woud like your opinions. We made the decision to not make full and complete PC backups--only specific folders. As a result, we aren't backing up the Syetem State. Do we need to backup the "Shadow Copy Components"?

Since the Shadow Copy Components contain System State information, the Shadow Copy Components need to be backed up by a full backup.

The Volume Shadow Copy components include the following:

System State writers	System files COM+ Class Registration Database SYSVOL Active Directory Cluster quorum Certificate Services Registry Internet Information Services
System Service writers	Removable Storage Manager Event logs Windows Internet Name Service Windows Management Instrumentation Remote Storage Dynamic Host Configuration Protocol Terminal Server Licensing Background Intelligent Transfer Service
User Data	Items that the computer does not require to operate. For example, Active Directory Application Mode.
