(I wasn't sure which section to post this in so I decided to put it here)
I have a few OpenVMS backup tapes which contain save sets (.bck) created by the BACKUP tool. Unfortunately, I do not have access to a physical OpenVMS system to read and restore them. I do however have FreeAXP... but from my understanding you can't connect physical hardware to it.
What I'm hoping to do is someone pull the .bck off the tape drive and transfer it to FreeAXP to restore it.
I did some research and came across this page:
It talks about how to use Linux's DD to grab files off a VMS tape created with the COPY command. Would I be able to use this method to grab the .bck file even though the tapes were created with the Backup tool? Is this even possible?
So I ended up trying vmsbackup and it wasn't what I needed. Instead of allowing me to pull the .bck from the tape, it would extract files within the saveset. So I instead tried DD.
This is what i discovered:
Openvms saveset tapes have essentially two files on them:
1) The tape header
2) The .bck
You skip the header file on the tape by using the Linux command:
mt -f /dev/yourtapedrive fsf
Now that you are positioned at the .bck file, dd it directly off the tape.
dd if=/dev/yourtapedrive bs=8192(i used the tape blocksize) of=/where_you_want_it_to_go/saveset.bck
I next made an iso with imgburn and so it could be mounted in FreeAXP. A MAJOR note is at some step in the process the saveset's file attributes are lost. Unless these are restored backup will not accept the file. But not to fear! You can restore them using the HP freeware tool @RESET_BACKUP_SAVESET_FILE_ATTRIBUTES.COM.

jiml November 09 2018 Thank you , Malmberg ! Exactly what I was hoping for . Reset key & all is well . JImL
malmberg November 09 2018 Eisner was upgraded to the current Multinet Release. As part of that a new host key was generated. The old key was incompatible with newer Linux.
jiml November 02 2018 ssh to eisner is now giving (on linux) "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!" , Has the server key in fact changed ?

peteherrera February 24 2018 How much does it cost to buy a complete OpenVMS hardcopy documentation set of the latest version
prohorenko February 17 2018 Please help to obtain the license on OpenVMS
malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.
