Some backup jobs fail

Hello,

I'm noticing recently that some of our VM backup jobs containing different VMs in a backup job are failing. 

The error messages related with these failures are as below:

Has anyone faced these kind of errors?

Thank you!

Re: Some backup jobs fail

Hello @isaqellari

Please try to add these variables to omnirc on CM and dataprotect-srv.apdurres: 

OB2IPCKEEPALIVETIME=180
OB2IPCKEEPALIVEINTERVAL=30
OB2IPCLINGER=1

(Remember to keep the file with no extension and restart the Inet after add them)
(Location: Windows: ProgramData\OmniBack\ | Linux: /opt/omni/)

Also add these others to global file on CM:

SmWaitForFirstBackupClientSec=7200
SmWaitForFirstBackupClient=140
SmWaitForNewBackupClient=180
SmMaIdleTimeout=280
SmDaIdleTimeout=240

(You should restart services after that. Keep it with no extension too)
(Location: Windows: ProgramData\OmniBack\Config\Server\Options\ | Linux: /etc/opt/omni/server/options/)

Also, please let me know the version you are running, because this can be a known issue.

Re: Some backup jobs fail

Hi,

 

please check if there is a firewall or an intrusion detection system between dataprotect-srv.apdurres and dataprotect-srv.local.

It looks like the connection is dropped.

 

Kind regads,

Re: Some backup jobs fail

Hi @isaqellari,

What Data Protector version are you running?

What transport method is the Backup job reporting? NBD / SAN / NBDSSL / HotAdd?

Can you attach the complete session report?

Re: Some backup jobs fail

Hi, 

I am confused. Is 10.20 or 10.02? Please send us the output of omnicc -version

==============================================================================
Messages from client: dataprotect-srv.apdurres
==============================================================================

dataprotect-srv.apdurres is the cell manager and it is a virtual machine.

DP Media agent is installed on a physical machine which is directly connected with tape library through FC.

Regarding the virtualized infrastructure which is being backup, the datastores where the VMs are residing are being presented to VMware hosts through FC protocol. Datastores are volumes of external SAN storage systems.

Where I can find what transport method backup job is reporting?

Re: Some backup jobs fail

you can check event logs in dataprotect-srv.apdurres for vepa_bar.exe crashes, and in such case create support case
