Yes, I’m trying to preserve the data on hard drive from future hardware failures.<div class=""><br class=""></div><div class="">I started out looking to backup to virtual tape.

Are you then looking at ways to perform backups of a physical system to virtual tape?<br class="">
<br class="">
I would probably give the virtual machine a really big disk and run backup to that remote disk and not try to play with remote tapes.<br class="">

<pre class="k9mail">If it was applicable to the situation, then VMSTPC would work great. It’s already installed on my Alpha, and I’m pretty sure there is a VAX binary for it in the VAX directory on there. I also have it installed on my RSX-11M+. It’s definitely a great tool. Just not for this. :-)<br class=""><br class="">Zane<br class=""><br class=""><br class=""><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> On Jan 25, 2018, at 2:54 PM, Armistead, Jason <<a href="mailto:Jason.Armistead@otis.com" class="">Jason.Armistead@otis.com</a>> wrote:<br class=""> <br class=""> Zane<br class=""> <br class=""> The program that Johnny is thinking of is VMSPTC<br class=""> <br class=""> <a href="http://www.digiater.nl/openvms/decus/vax86a/bnelson/vmstpc/vmstpc.c" class="">http://www.digiater.nl/openvms/decus/vax86a/bnelson/vmstpc/vmstpc.c</a><br class=""> <br class=""> Note sure if this is the latest, but it came up in the first set of Google search results for "VMSTPC"<br class=""> <br class=""> Good luck<br class=""> Jason<br class=""> <br class=""> <br class=""> -----Original Message-----<br class=""> From: Simh [<a href="mailto:simh-bounces@trailing-edge.com" class="">mailto:simh-bounces@trailing-edge.com</a>] On Behalf Of Johnny Billquist<br class=""> Sent: Thursday, 25 January 2018 5:48 PM<br class=""> To: Zane Healy; Tim Shoppa<br class=""> Cc: <a href="mailto:simh@trailing-edge.com" class="">simh@trailing-edge.com</a><br class=""> Subject: Re: [Simh] VAX Tape Emulation?<br class=""> <br class=""> Zane - unless I remember wrong, there is a tool from DECUS to copy tapes to a file image, and then get that back to a tape again.
