To use the dump and load commands, SAP ASE must be able to communicate with Backup Server.
Backup Server must be running on the same machine as the SAP ASE.
Backup Server must be listed in the master..sysservers table. The Backup Server entry, SYB_BACKUP, is created in sysservers when you install SAP ASE. Use sp_helpserver to see this information.
Backup Server must be listed in the interfaces file. The entry for the local Backup Server is created when you install SAP ASE. The name of the Backup Server listed in the interfaces file must match the column srvnetname name for the SYB_BACKUP entry in master..sysservers. If you have installed a remote Backup Server on another machine, create the interfaces file on a file system that is shared by both machines, or copy the entry to your local interfaces file. The name of the remote Backup Server must be the same in both interfaces files.
The user who starts the Backup Server process must have write permission for the dump devices. The “sybase” user, who usually starts SAP ASE and Backup Server, can read from and write to the database devices.
SAP ASE must be configured for remote access. By default, SAP ASE is installed with remote access enabled.
