Problem restoring single files from a windows 2016 fileserver from our vmware environment

I have a problem restoring single files from a windows 2016 fileserver from our vmware environment. The backup itself (policy type vmware) is working fine. A client netbackup software has been installed on the win2016 server and i am sure it was working some month ago. Now i am no longer able to do restores on a file basis.

NetBackup VMware policy restore error  (2820)

So i did some communication tests and bpclntcmd and bptestconn are looking fine, but when i use
"bptestbpcd -verbose -debug -client <servername>" it shows me a communication error. 

[root@franbp1 ~]# bptestbpcd -verbose -debug -client entfrafs2

@Kai2209

Is there an Antivirus or something that is running on the client, or maybe you have some TCP filtering on this server? Maybe that is stopping the connection from being made.

In your bpcd.log, there is this error  <16> process_requests: setsockopt failed: h_errno 10038 which points to TCP/IP issues on your client. Here are some links that Marianne has posted before.

You can see that the communication from 10.64.2.40.50749 TO 10.64.4.80.1556 fails. 

I can see that Client and the Netbackup server are on two dfferent networks. Firewall might be blocking the access.

Please try telent from netbackup server to client on port 1556 and see if it work. If not then fix it.

Re: Problem restoring single files from a windows 2016 fileserver from our vmware environment

thanks SymGuy-IT but there is no firewall in-between the networks. Telnet from 10.64.2.40 to 10.64.4.80.1556 works fine

[root@franbp1 ~]# telnet 10.64.4.80 1556
Trying 10.64.4.80...
Connected to 10.64.4.80.
Escape character is '^]'.

 

[root@franbp1 ~]# bptestnetconn -v -c -o 5 -t 10 -H entfrafs2
adding hostname = entfrafs2
------------------------------------------------------------------------
Connecting to 'nbsl/HSFactory'
CN: entfrafs2 : 4 sec [TRANSIENT] PBX: Yes VNETD: Yes BPCD: Yes

maybe i misunderstand this command but looks like port communiation is ok. Smiley Sad

Re: Problem restoring single files from a windows 2016 fileserver from our vmware environment

Have you verified the connection both ways, not just from media server to client but also from client to media server?

@kruntons1

you are right i did some dns tests and they all were sucessful. but this one shows me a problem i guess? but do really understand what i means 

C:\Program Files\Veritas\NetBackup\bin>bptestnetconn -v -c -o 5 -t 10 -H enigmab
adding hostname = enigmab
------------------------------------------------------------------------
Connecting to 'nbsl/HSFactory'

Re: Problem restoring single files from a windows 2016 fileserver from our vmware environment

Can you run this on the client <installpath>/bin/bpclntcmd -hn <master or media>

Are you sure that the media server that is doing the restore is on the media server list of servers on the client?

Re: Problem restoring single files from a windows 2016 fileserver from our vmware environment

Can you also attach bpcd log from client and output of "netstat -ano"

Re: Problem restoring single files from a windows 2016 fileserver from our vmware environment

@krutons1

result of bbclntcmd <masterserver>

C:\Program Files\Veritas\NetBackup\bin>bpclntcmd -hn enigmab
host enigmab: enigmab at 10.64.2.40
aliases:     enigmab     10.64.2.40

yes i am sure the master and media servers are listed

thanks
