Dear all,
I'm using bacula 9.6.5 in a production for a month now. I'm experiencing random
backup failures from my clients. Specific hosts report errors like the outputs
attached. The same host is able to perform backup at some other time. The error
is more often at large backups (more errors at full backups than incremental,
more errors at hosts with large data sets).
I have tried to implement heartbeat interval
(https://www.bacula.org/9.6.x-manuals/en/main/Client_File_daemon_Configur.html#SECTION002210000000000000000)
but there is no improvement.
The error occures also on hosts in the same zone as bacula server (no
router/firewall in between).
Storage deamon is installed on the same server as bacula director. I'm using
File cloud driver (backup to local disk via cloud resource).
Could you please suggest a solution or a way to troubleshoot this further?
Thx!
Regards,Ziga Zvan
