5.12 Server-side Copy Feature

The server-side copy feature is enabled by default and does not need any configuration change on the client or server.

Server side copy support on Micro Focus CIFS server enables Windows workstation clients to make use of server-side copy that can considerably improve the performance for file copy operations within the same share as the file data need not traverse the network.

Server-side copy is invoked automatically through SMB protocol for all eDirectory and Active Directory users when they copy files from one location to another location on the same share. When a file copy operation is initiated from CIFS client, the client issues FSCTL_SRV_COPYCHUNK request to the CIFS server. Upon receiving this request, the CIFS server reads the file date from the source location on the disk and writes it to the target location on the disk.

Server-side copy is invoked only when the source and target locations of file copy are in the same CIFS share. It is not invoked for file copy operation between two different CIFS shares on the same or different server.

For example, a file copy from \Share1\Dir1 to \Share1\Dir2 invokes server-side copy. Whereas a file copy from \Share1\Dir1 to \Share2\Dir2 does not.
