Is there a dump type which will allow me to replicate a file structure on my client to the server... ?
The standard "comp-user-tar" will tar and compress the files if I am not mistaken?

Essentially, my client has around 1.5 million files (around 200GB) and these files rarely change, only new files are added.
To have Amanda backup this whole structure every time and compress is is just a waste of resources as there may only be 20mb of new files a day...
Therefore if it simply just copied the file structure as it is (no compression or tar) and rsync the files, it would essentially sync only the new files.

Is this even possible with Amanda, or am I best to re-invent the wheel and create my own backup scripts?
