I had configured networker 9.0 block based backup for standalone exchange 2013 following video "NW9 Lab 5 Part 1 - Configuring and Running BB Backups for MS Exchange". But when making backup, it is failed. I attached logs. Please all help me issue' thanks!
And where is that video?
Log indicates client can't get to server names networker.localdomain. Is this really how server (backup server) is called and client can reach it? Note that most likely server can reach client and this started backup process of course, but on the way back something is breaking connection. Firewall, routing or wrong configuration option might be in play here.
Looks like Device / pool is not enabled "client direct". Can you check device and pool configuration to enable Client direct; and Enable client direct and try the backup.
