A share is a file folder that is available to users across the network. You can assign permissions and settings to a share to suit the security needs of different applications and organizations.
Shares can have shadow copies that are automatically added to a designated folder. You can use a shadow copy to recover deleted, overwritten, or modified files.
Two formats are available for a share file:
Server Manager simplifies the creation of shares by providing predefined share profiles.
To use the SMB Share Advanced profile, the File Server Resource Manager (FSRM) must be installed as a service on the server.
Shadow copies allow you to automatically create copies of files in designated folders. Although convenient, you should not use shadow copies as an alternative to a true server backup. They are not stored off site, and they cannot be easily managed.
The shadow copy system can store up to 64 copies of a file.
Important: If you implement shadow copies on a clustered file server, ensure that the %SystemRoot% resolves to the same name on both the principal system and the failover system. If they do not match, shadow copies fail. For example, if %SystemRoot% is C:\Windows on one system and C:\Win on the other, the service that runs the shadow copy task can fail in the event of a system failover.
