Hi Per,

Lifted from:

http://www.amanda.org/docs/manpages/amanda.8.html

"ctimeout int
    Default: 30 seconds. Maximum amount of time that amcheck will wait for 
each client host.

dtimeout int
    Default: 1800 seconds. Amount of idle time per disk on a given client that 
a dumper running from within amdump will wait before it fails with a data 
timeout error.

etimeout int
    Default: 300 seconds. Amount of time per disk on a given client that the 
planner step of amdump will wait to get the dump size estimates. For 
instance, with the default of 300 seconds and four disks on client A, planner 
will wait up to 20 minutes for that machine. A negative value will be 
interpreted as a total amount of time to wait per client instead of per 
disk."

I know these won't have changed, but what are yours?

Yes, define a dumptype, also on the abive link.

define dumptype testing {
    comment "Test backup, no compression, do indexing, no recording"
    normal
    index no
    record no
}

Then change in your disklist to something like:

suretec /var testing
