I was looking thru my list of services on my Windows 2003 Enterprise Server and noticed that the Volume Shadow Copy service is set on manual is isn't started. I would like to turn it on because I have a backup program that has Volume Shadow capabilities (Acronis) and would like to use it for my backups, such as SQL databases, Exchange Server mailboxes, documents and files, etc. I'm concerned on why the Volume Shadow is turned off by default. Is there anything I should be concerned about by turning this on to automatically start up, such as corruption, performance degrade, etc? This server is a domain controller, IIS web server and File Manager.
