This option is only valid if OFS or onlineimage backup has been configured.For an online image backup, use this option with the backup image command, theinclude.image option, or in the dsm.opt file.For open file support operations, use the presnapshotcmd option in an include.fsstatement or in your client options file (dsm.opt).If the presnapshotcmd fails it is assumed that the application is not in a consistentstate and the client stops the operation and display the appropriate error message.Supported ClientsThis option is valid for all Windows clients. The Tivoli Storage Manager client APIdoes not support this option. The server can also define this option.436 IBM Tivoli Storage Manager for Windows Backup-Archive Clients: Installation and User's Guide
