You can throttle rsync with --bwlimit, unless you would need to use

duplication of the data bacula stores in order to put a copy on

location (via internet). Of course it is not possible to copy
simply the
backup file because it is too big.
One suggestion. Make the volumes smaller. 1 to 10GB should be fine.
Then use rsync (possibly run from a cron job) to send the volumes
offsite.

My bacula setup is pulling the remote files to on disk volumes that
are 5GB each. I have a final job that looks for what disk volumes
have
changed from the previous backup and writes those volumes to tape.
I could use rsync(1) to copy the 5GB volumes to another server and
did
consider copying those disk volumes over the net to a remote
location. I
decided against this approach as the rsync(1) would consume my entire
bandwidth. Not a bad solution for incrementals, but not good for
fulls.

I'm thinking of a solution (maybe not so "simple"):
- Before a job starts, a small script checks if the file exists and
if it is a socket (assuming it is possible to know the file name at
this time). If it is a real file (which means it is a new file, the
script can replace the file by a socket
- The FD sends data into a socket and a small script listens on the
socket. For all data, it writes it at the end of the "real file" and
can do the copy (or prepare it for a copy after all).
Is it a possible solution ?
