How fast? A 100 Mbps connection equates to 6.25 MB/s or so. With 
compression, let's say an average of 10 MB/s. For 1 TB = 10^6 MB, it 
would take at least 10^5 seconds or just over 27 hours. A full backup of 
a multi-terabyte system would take days.

Bacula expects its TCP connections to stay up for the entire job. It 
will fail jobs, rather than attempt re-connects. Bacula is targeting 
local network backups, rather than Internet backups, since the Internet 
is generally not fast enough. One network hiccup can fail the job on day 
3. There may be a way to resume jobs, but I am not sure it is possible 
to resume failed jobs.

Also, there is a maximum runtime for a single job that must be dealt 
with. It may require a patch and recompile to increase the max runtime.

My opinion is that the Internet is not yet fast enough or robust enough 
for full backups of multi-terabyte systems. I would store fulls to local 
disk and then rsync to GD. It should be feasible to store incrementals 
directly to GD. However, if none of the filesystems are robust enough, 
then I would table the whole idea until they are.
