Lines: 79 I recently posted a request for information about the possibility of backing up an Ultrix system to a VAX/VMS system over TCP/IP. I received responses regarding two current products, and a third response containing a past summary of information about network backups generally, from which I distilled the third item included here. Edited summaries of the information I received follows. - Paul ------------------------------------------------------------------------ 1) From: nowicki@Legato.COM (Bill Nowicki) You recently posted a note about network backups. Our company recently released a product that does that. The first release is for SunOS, but Ultrix is currently being tested, and VMS can be done on request. Please contact us for more information, at 415-329-7880. Thanks, Bill Nowicki Legato Systems --------------------------- Legato NetWorker: The Complete Backup and Recover Product Legato NetWorker is a unique, easy-to-operate product that protects files against loss, network-wide. At the same time, it speeds file recovery so users never waste time re-creating valuable work. Legato NetWorker easily adapts to your environment. It uses industry-standard network protocols and no changes are made to the operating system of any platform. And as your network and volume of files expands, NetWorker has the capacity and performance to handle the load. ... Available now: Call your local Unix software distributor or Legato at (415) 329-7880. 2) From: VANCE@TGV.COM (L. Stuart Vance) Our MultiNet TCP/IP for VMS package supports an RMT (Remote MagTape) server, allowing you to use the UNIX rdump and rrestore utilites to backup/restore files from your ULTRIX box to your VMS system. Please drop me a note if you would like any additional information/details. ... the server allows UNIX systems that support the rdump and rrestore utilities and PCs that have FTP Software's package (which has a port of rtar) to access the VMS tape drive over the network. Additionally the RMT server allows you to rdump/rrestore to a VMS file (which you can then copy to tape) if the rdump/rrestore directly to tape takes longer than you'd like. 3) From: Alan Strassberg >From: tony@rata.vuw.ac.nz (Tony Martindale) - past summary re: network backups From: Hans W. Barz, R.1032.3.34, CIBA-GEIGY, 4002 Basel, Switzerland mail: whwb@cgch.uucp ... if you connect the systems with NFS you can write the backup with standard system backups to the central site. Retrieving a certain file for restore is awkward using NFS since the most backup routines scan through the whole backup (assuming it is a tape) to find the file. This delivers a high network load with a low outcome. There is one similar solution around on top of Hyperchannel (at least for VAX'es and IBM's) named HYPERTAPE (contact: MultiStream Systems Incorporated, Denise Yegge, P.O.Box 497, Excelsior, Minnesota 55331, USA). They had the plan to run it also on top of TCP/IP. This information is from Feb. 1988, you may check if it is still true. *** note - I can find no entry for MultiStream Systems in the 1989-1990 Minneapolis, MN phone book - anyone know if this company still exists? - PJW *** -- * Paul J.
