Hi all,

I've been using Bacula to back up my NAS for some time, and it's been working well. I see effective backup rates of about 30MB/s all told (100MB+ unspooling from SSD to tape, maxing out the LTO6 drive).

Unfortunately when I added my desktop PC to the backup cycle, I found that the effective rate dropped like a rock, to single-digit megabytes per seconds.

The machines are both fairly fast -- the desktop machine (backup source running the FD) is a Ryzen 5 5600X, and the server (with the SAS SSD and tape drive) is an Intel Core i5-9400. The network is gigabit end-to-end, and the transfer rates I'm seeing are very poor. Other applications taking the same path are much faster.

Both systems are running Debian derivatives -- the desktop runs Mint with Bacula 13.0.4, and the server runs Ubuntu 24.04 with the same version of Bacula.

Is there anything I can do to improve performance backing up over the network, before I resort to a nightly Rsync from the workstation to the server and backing up from there?

Thanks.

Phil.
