Do 'amadmin CONF find' list the dump? Do the tapelist and log are at the right place $ amgetconf CONF tapelist $ amgetconf CONF logdir
I can grep through the log.<datestamp>.0 files on machine B and find the DLEs and the names of the Vtapes. My reverse AMVAULT command looks like this: amvault --dry-run --src-timestamp 20150208180002 --fulls-only -o tpchanger=vtapes-on-spool --dst-changer LTO5-Robot --label-template "ad5-%" daily FWIW, back on machine A the amvault command had the tapes in the DST position: amvault --src-timestamp 20150208180002 --fulls-only --dst-changer vtapes-on-spool --label-template "VTAPE-%%%" daily and the “from” changer was the main one in the configuration.

You can do it from both machines: - run amvault on machine A to copy the dump to vtapes - transfer the vtapes to machine B including the -tapelist entries and the -log.<datestamp>.0 files. - run amvault on machine B to copy the dump from vtapes to LTO5.

I will soon get rid of most of my older tape drives and I want to preserve some of the backups done on those tapes. Machine A will still have the old tape drive available for a while. I’d like to read the backups onto disk on machine A, and then copy them over the network, over to machine B, and write them to a newer tape drive on machine B. It looks like AMFETCHDUMP will de-compress the files and try to undo the backups, so I don’t think I want that. Should I use AMVAULT on both machine A and machine B? I could tell machine A to read from the old tape drive as the secondary media (per terminology in the man page) and write to “disk” as the “tertiary” media. Then I copy the files over to machine B and reverse the process. Will this work? (Machine B isn’t here yet. Also, forgive my up casing the AMANDA words, but my mac keeps trying to respell everything and my brain won’t cope with that today. ) Deb Baddorf Fermilab TL;DR : I’ve only got a year’s worth of data on LTO2 tape, so this seems worth doing. I had older yet SDLT tapes before that, lots of them. Those I won’t try to convert, but will save the heroics until someone absolutely requires some old data. Learning a little about AMVAULT wouldn’t hurt me either, so this seems like a worthwhile project.
