No, by dump, I meant the program 'dump', as opposed to the program 
'tar' (usually gnutar, and it needs to be at least version 1.13-19, 
plain old 1.13 won't do, its busted, get 1.13-25 from alpha.gnu.org's 
ftp site)

tar should be able to do this, no problem, although if you leave the 
email agent running full time (I do, I'm on dsl) then its every so 
often scans of your mailbox at your ISP might occasionally cause a 
"file changed while we read it" message from tar if its updateing the 
mail spool while tar is reading it.

However, since you have /var in the disklist, and tar traverses all 
subdirs below the named one, there must be a more fundamental 
problem, possibly related to permissions.  You did configure and 
build amanda as the user 'amanda' didn't you?  And then become root 
before installing her?
