I have a similar setup where my fulldumps are Sunday nights and my
"incrementals" are Mon-Fri. I have 2 separate configurations:
'fulldumps' and 'incrementals'. The 2 are not necessarilly "state"
consistent. My fulldumps are consistent with themselves, my
incrementals are actually nothing more than a basic normal amanda
config which gets run once per day, 5 days a week.
My incrementals are meant to stay on site, also include periodic
level 0 backups, and are over 3 week window, after which I recycle
through the tapes.
My full backups are level 0 only, meant for off site storage, and are a
1 year window, after which I recylcle tapes. They share the same
changer, but have different configurations and slightly different
disklists.
My goal is to have something both on site; which I can restore from
immediately if I need it without having to wait for or request from
the offsite storage company; and something offsite for long-term
archival purposes to assist in disaster recovery efforts should we
ever need them. So far, it's worked out well.
Both configurations are managed by calling amdump each night from
cron with the appropriate name of the configuration to be run.
So, my fulldumps config crontab entry looks like this:
55 23 * * 0 /usr/local/amanda/sbin/amdump fulldumps
and my incrementals config crontab entry looks like this:
55 23 * * 1-5 /usr/local/amanda/sbin/amdump incrementals
I make sure the right tape is in the right slot with these entries:
45 23 * * 0 /usr/local/amanda/sbin/amtape fulldumps slot 6 2> /dev/null
45 23 * * 1 /usr/local/amanda/sbin/amtape incrementals slot 1 2> /dev/null
45 23 * * 2 /usr/local/amanda/sbin/amtape incrementals slot 2 2> /dev/null
45 23 * * 3 /usr/local/amanda/sbin/amtape incrementals slot 3 2> /dev/null
45 23 * * 4 /usr/local/amanda/sbin/amtape incrementals slot 4 2> /dev/null
45 23 * * 5 /usr/local/amanda/sbin/amtape incrementals slot 5 2> /dev/null
I hope that helps.
