usage pattern: xfsrestore to mirror disks

[Jakob Praher <jp@hapra.at>]

hi all,

first of all: I am a very happy user of xfs for a long time now.
I use xfs in tandem with lvm2 and I have to say I am very pleased.

Now a question:

There are two modes of using xfs(dump,restore): non-cumulative and 
cumulative. Is this cumulative mode also good to work with full dumps 
(level0). E.g. the data I have to mirror is not large, and I don't want 
to rely on inventory data. So I want for instance if between two full 
dumps a file F was deleted, it should get deleted when I do xfsrestore 
for the second time.

I don't keep the xfsdump output files but i just apply them via ssh. So 
something like that would be great!

Maybe someone can shed some light on that.

thanks
