For my own archival storage, I’ve found it easiest to create a second
configuration. No amvault.
Just a second cronjob that I run one weekend per month. It ONLY does level
0’s, and uses the same
DLE that my “daily” job uses. But a different amanda.conf so that I can
specify no-incremental, no
re using tapes. More detailed info, if this option appeals to you.
It takes longer than a daily job, for me, but uses the same tape drive.
(Daily jobs don’t get to run
on the weekend when this occurs).
But I think you’ve already considered this option, and didn’t go that route.
