OpenVMS backup over TCP/IP connection

I currently manage 7 sites with AXP severs, all connect via a TCP/IP in a WAN network. Is there a way and/or product that would allow me to execute OpenVMS backups over the network so I can use my Central AXP server as a repository for all remote sites?

There use to be a software called Remote Tape Facility that will allow a client node to use locally a remote tape drive. The software work over DECnet.

Please advise.

Re: OpenVMS backup over TCP/IP connection

I know nothing, but Google found this:

http://www.ttinet.com/doc/rdf.html

I don't do it, but I hear that it's possible
to run DECnet over a TCP/IP network:

Also, when you get DECnet up, this might be
useful (and cheap):

Re: OpenVMS backup over TCP/IP connection

See this ITRC thread "Testers for virtual tape library wanted" http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=965502

From David Jones' note

"It should build on any Alpha running 7.2 or higher with DECC 6.0, but most development has been at 8.2.

The code is an update of Wolfgang Moeller's old remote tape driver using TCP/IP instead of DECnet (ZT_DRIVER.MAR is virtually unchanged). I use the software to backup my AS800 at home to a 300GB disk drive connected to a Windows PC."
it depends

Re: OpenVMS backup over TCP/IP connection

DECnet-Plus operating over the IP transport and BACKUP can together provide this. Unmodified. Transparently. No added products or licenses. Supported.

One concern here is that you can have critical security information traveling over the WAN, though BACKUP encryption can certainly address this potential exposure.

There's an unsupported pass-through tool (for DECnet) in the FAQ.

And there are remote storage library facilities and storage archival tools around. The ABS product, for instance.

Re: OpenVMS backup over TCP/IP connection

Two additional pieces of information based of the replies received:

1. Currently running DECnet IV not OSI (haven't found a good reason to upgrade).

2. DECnet's protocol is filtered by the Switches, so there is no DECnet between sites.

I'll try to do some testing in the next few days and post my findings.

Thanks to all.

Now 2. gives You a good reason to upgrade to DECnetPlus: with DECnet-over-IP You can continue to use backup to remote (decnet-) saveset.

Re: OpenVMS backup over TCP/IP connection

For sake of completeness.

- Did you want to directly write to tape on the remote site/side or is a saveset fine?

- If a saveset is fine, then just use an NFS
presented device?

Re: OpenVMS backup over TCP/IP connection

We have used a product called TAPESYS from Software Partners (www.softwarepartners.com)for years. It's a tape and backup management app. and works with a remote backup component called THRUWAY. It runs over TCP/IP. It's certainly not fast but it works.

Re: OpenVMS backup over TCP/IP connection

Multinet has a RmtAlloc module that gives you a tunnel to a remote tape or CDrom device ... I use it monthly to back up a Vax3100 in my second cluster to a DLT tape drive on my primary cluster.

This runs over TCP/IP using the Multinet product; you need Multinet on both ends.
