Use the at backup_server_name clause to send dump and load requests over the network to a Backup Server that is running on another machine.
See the Reference Manual: Commands
Sending dump and load requests over the network is ideal for installations that use a single machine with multiple tape devices for all backups and loads. Operators can be stationed at these machines, ready to service all tape change requests.
dump database pubs2 to "/dev/nrmt0" at REMOTE_BKP_SERVER
load database pubs2 from "/dev/nrmt0" at REMOTE_BKP_SERVER
The backup_server_name must appear in the interfaces file on the machine where SAP ASE is running, but does not need to appear in the sysservers table. The backup_server_name must be the same in both the local and the remote interfaces file.
The remote backup server name length limit for dump and load commands is 255 characters.
