I backup many clients all have a similar config. They use Client side de dup and backup up to a centralised puredisk pool.
Two clients are giving me the same error and I am having a lot of trouble backing them up.
They are windows 2008 clients.
The error I always get is bpbkar waited for empty buffers xxx times, delayed xxxtimes. Then the job fails with a 14 file write failed error.
I backup 328 clients all others are fine.
Master Server and client version is 184.108.40.206.
Can anyone help?
Solved! Go to Solution.
These 2 clients, what are their differences with other clients?
Less memory? Too many applications running - higher load? Note that client dedup requires the client to perform the dedup so the client needs to meet certain "standard".

Is there a firewall between the client and media and/or master server?
Check that ports 10082 and 10102 are open in both directions.
Also verify that Windows firewall on client is turned off.
You will also need bptm log on media server since we see in Job details that bptm process is reporting error 2060017 and 2060005.
Those ports are closed from client - but they are closed for all clients and the other 300 don't have any issues. Will disbale client side de dup now and try another backup.
I have done this in the past and it's been painfully slow mind.
Disabling client side de dup led to both backups failing very quickly with a socket write failed 24 error. At least with the client side de dup enabled I did get to write some data.
For Netbackup to be able to backup the client with client side dedupe, these ports are required.
For testing you can open the ports for some time and try a backup with client side dedupe enable.
I telnet from media server to client and vice versa ports are open and I can write data to pool but backup always fails with a 14 file write failed error on both clients.
Always witing for empty buffers message in job details.
