I'm dumping an ext3 filesystem. The backup medium is a Samba share. So 
you'd see the dump file on the Win2003 server's disk.

ext3 does have extended attributes where ACL's can be stored, so once 
there's more support for ACL's in Linux, the infrastructure is there to 
store them and back them up.

My backup script runs dump and then runs "restore -C" (compare) to verify 
the dump. One caveat here is that dump sees the raw device while restore 
sees only the mounted filesystems, so files that are hidden by mount points 
(including the mount point itself) are not available to restore to check 
against the dump. This can cause some spurious miscompare warnings.
