Hi, We have set up a backup server that uses encryption in the File Daemon. However we find it is really slow, in fact we are only getting about 80Mbps (megabits, not -bytes) throughput while running 4 backup threads. This is backing up from an NFS-connected disk backup host that can easily saturate a 1Gbps link when I just dd the contents of a large file to /dev/null on the backup server. It's actually taking us nearly a week now to do a fortnightly backup of 16TB.
I've noticed that crypto cards from Exar are supported by OpenSSL and seen to provide support for AES-CBC. From a previous message on this list: http://adsm.org/lists/html/Bacula-users/2010-04/msg00232.html it seems someone looked at patching to support offload, however I cannot find any outcome from this. If it is supported in any way, I'd be happy to know. If not, what would be the best way about getting it implemented?
