i'm going to jump into the middle of this thread as this is currrently my
biggest issue with bacula. my 'problematic' filesyste is this:

| 1,249 | birch         | 2008-07-27 00:25:05 | B    | F     | 16,060,382 | 
1,090,359,097,266 | T         |

16M files at just about 1.1TB. it currently takes me days go get this backup up 
via nfs mount to
a DLT-4 tape drive. the filesystem is on a Netapp, mounted via nfs with the 
netapp recommened nfs
options, 1000Mb/s network. here is the summary from the last full backup:
