Hello Sainath,

I see something already that points to wrong configuration.

1.- Client retires has to be set to 0

2.- All values on the right side of the advanced tab in group configuration has to be set to 0

3.- Make sure the "backup renamed directories" option is not checked in client configuration.

4.- Make sure there is no directive set for the client.

Can you please attach screenshots of all the group configuration tabs and same for the client?

Thank you,

Carlos

Are you using 8.0 or higher version of NetWorker server ?

CarlosRojas · Answer

Hi Sainath, Can you please disable the 'Perform virtual Synthetic full' option in the group properties? Group properties-> Advanced tab-> bottom right part of the screen. If you don't see this option then enable the diagnostic mode by clicking on 'View->Diagnostic mode'. Thank you, Carlos

Hi Crazyrov, We are Using  NetWorker 8.1.1.7.Build.333 Thanks & Regards Sainath

What is the Os of the client machine that you are using ? And, are the full backups completing without any issues ?

SainathPawar · Answer

Hi Crazyrow, We have Windows Server 2003 & 2008 OS Machine. Yes Full Backup has been completing without any issue. Thanks & Regards Sainath

SainathPawar · Answer

Hi Carlos, I have Disable the ' Perform Virtual Synthetic full'  option in the group . But still it has been Failed with the Same error. Thanks & RegardsSainath Pawar

crazyrov · Answer

Well, we have tried it on server 2003 and it did not work. The reason given by support."NMM 2.4.1 is not compatible with Windows 2003".

well, the windows 2008 should work though. i would suggest you to install NMM 3.1 with NetWorker client 8.1.1 for windows 2008. The file-system backup is traditional (without snapshot).

SainathPawar · Answer

Hi crazyrov, Thanks For the update. Is NMM 3.1 compatible with Windows Server 2003 ? Thanks & Regards Sainath

crazyrov · Answer

No, none of the NMM that are supported by NetWorker server 8.1.x support windows 2003.
