I’ve run AMVAULT on machine A and copied my dumps to vtapes.
I’ve scp’ed the vtapes to machine B, along with the
tapelist entries and the log.<datestamp>.0 files
AMVAULT on machine B insists that there are “no disks to vault”.
Can anybody think of anything I’m missing?
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.
