really long). and during this time, i had a LOT of network traffic
between my backupserver and my workstation (i mean like 850kB/s
continuously for 5-10 minutes). it's almost as if the whole /home was
sent to my workstation or something. is this normal behaviour, or does
anybody recognize it? or have i possibly compiled or ./configure'd
amanda completely wrong?
Yes, the whole /home is sent to the workstation.
This is done because if you made the backup with e.g. some special
version of dump, the client knows how to unpack it. The server could
be a completely different beast.
And even when using gnutar, which is the same format accross all
architectures I know, it's not possible. How would the local gnutar
write to the remote machine? Remember, Amanda is just the scheduler/
invoker of the real backup program.
(If you have strong programming skills, you could add an utility
to gnutar, that extracts only the wanted files, packs them again
on the fly to send them over the network, where another gnutar program
accepts only the useful bytes. And while you have built your expertise,
you could do the same for all the dump variants. :-) )
