If you have a failed backup, you should start by looking on your NetWorker server in the folder /nsr/tmp/sg/[group name] - there are a number of small files in there. Open them all and have a look to see if you can identify the cause of the failure.
If you can't, then go to the NetWorker client machine and run a test backup from there with a command like this:
save -s [server_name] -vvvvv -D9 /etc/hosts > testsave_out 2>&1
replacing [server_name] with the name of the networker server then check the testsave_out file for errors.
If this fails, it will give you more information around the cause of the failure. If it succeeds, try backing up data that is equivalent to the data you wish to backup on this client and see if that fails or succceeds.
Perhaps you wish to show us log first to see where and at which stage it fails. From there on it will be easier to determine next steps. You can see log by doing nsr_render_log /nsr/logs/daemon.raw > /tmp/foo.bar Then foo.bar will contain rendered log in which you should extract part which is reveleant to your problem.
An incremental backup will backup all changes since the last incremental or full backup; if there is no preceding backup then it will backup at level full regardless of what the schedule says. That is why it appears to be backing up at level full all the time. The next question is why it is failing, since it is always failing it is probably a configuration issue, if you could post some details of what you are backing up, how you have configured it and what error messages you are getting we may be able to help.
There are 2 different questions here, one about the backup levels (full and incremental) and second about the failure of the backup.
I would say let's focus first on the failure of the backup which is more important and we can look into the levels later on.
For the backup failed, we would need some kind of output, for instance you can open the group report in NMC and check out what the error message is, or you can also check the logs for the group, as Bobby said, which are located under /nsr/tmp/sg/group_name
For the backup level issue, where are you configuring the schedule, on the client or in the group? Please note that any value on the group will overwrite any value on the client, so if you set the schedule on the client and a different one on the group then the one set in the group is the one that will be used.
Also, if the first backup full failed, that means that you don't have any valid full, so NetWorker won't be able to take any incremental, as the full failed, so that's why you need to focus first in solving the group failure and then once fixed the backup level will be honored correctly.

Hi Priyam,
Welcome to the world of NetWorker!
If you have a failed backup, you should start by looking on your NetWorker server in the folder /nsr/tmp/sg/[group name] - there are a number of small files in there. Open them all and have a look to see if you can identify the cause of the failure.

replacing [server_name] with the name of the networker server then check the testsave_out file for errors.
If this fails, it will give you more information around the cause of the failure. If it succeeds, try backing up data that is equivalent to the data you wish to backup on this client and see if that fails or succceeds.
