I have a question about the dumporder parameter in amanda.conf.

I want to back up 4 servers.  The volumes of data on disk are as
follows:

Server1
 /dir1   298G
 /dir2   74G
 /dir3   66G
Server2
 /dir4/backups/backup1   57G
Server3
 /dir5/backups/backup2   28G
Server4 
 /dir6/backups/backup3   9.5G

My problem is that all the data to back up on Server2, Server3, and
Server4 isn't necessarily ready to be backed up until around 7am each
morning (this could possibly be moved to as early as 5am, but not by
much more than that).  Server1 can be backed up at any time I wish
during the night.  The sizes of the data to be backed up are fairly
static - I don't anticipate massive sudden increases (touch wood).  I
also now have the capacity to force full backups each night.  The data
on Servers 2, 3, and 4 will change completely each night anyway, so I
know I'll be backing up the amounts as above, even if I used Amanda the
classic way of level 0s and level 1s.

How can I configure the dumporder parameter to first back up Server1 (I
know how long a level 0 of that will take to dump) before doing the
other servers?  Then I can plan more accurately when to actually start
the backup job.

Something like "SSsS", if I want to back up Server1 first, then Server2,
then Server4, and then Server3 (Server3 takes the longest to create the
data to back up, so should come last)?

No sooner had I gotten the backup server to work with two tape drives,
than one tape drive died.  Now I have a fancy new tape drive with lots
of capacity, so I'm trying to consolidate backups that previously were
done seperately, i.e. previously Servers 2, 3, and 4 weren't part of the
Amanda backup routine at all.

I'd appreciate any advice.
