tcpip show version

"data"? Files? Files where file attributes are important? There
are many ways. FTP, NFS, RCP, SCP, ...

Why? What's the problem with COPY/FTP?

That might depend on what your "backup command" would be doing. It
is possible to use DECnet over IP, and that might help.

tcpip show version

"didn[']t work" is not a useful problem description. It does not say
what you did. It does not say what happened when you did it. As usual,
showing actual actions (commands, code, ...) with their actual results
(error messages, ...) can be more helpful than vague descriptions or
interpretations.

Define "better". Is there a significant difference?

BACKUP can be reliably used over the network. The BACKUP command will only allow you to reference a backup saveset on the remote system (not individual files). BACKUP does NOT have an option to use TCPIP rather than DECNET. If you are not able to access the remote system via DECNET (e.g. DIRECTORY command, or SET HOST command), you would need to configure the systems to use DECNET over IP.

I use a procedure to create a snapshot of a production system and make a copy for a hot standby system. I do this by doing a "backup/image/ignore=interlock sys$sysdevice: hostname::disk:[backup]backup.bck/sav". Then I do a "submit/remote command.com" to restore the backup saveset on the remote system to an alternate boot drive.
