Windows server will not perform incremental backup
I have one specific server that will only perform a full backup every day and will not run an incremental. It's in a group that is set to run a full backup once a month and then incrementals all other days. There are other servers in the group and they all do the incremental backups like they're supposed to. The server is Windows Server 2008 R2.
I'm on Networker 8.2.0.0.445 and Data Domain 5.5.0.9-471508
No Events found!

Correct. With -c you instruct NW to place backup using that index space and not any other. Most likely there is some mistake in name resolution somewhere which is causing this to be written under what is not proper space so whenever it does nsrim, it clears index and next backup finds that it needs to run full level. You don't have run full against whole machine... you can create another resource for some smaller save set and test it.

Check for the log messages.
The most likely problem is that the full cannot be found. And each backup cycle must started with a full.
However, this should clearly be stated.
The following command line shout point this out even better. At the NW server you should run:
savegrp -c -l incr -G

Did you try to use save -c in backup command to see if that changes anything?

jmorgan48,
Do you see any message stating that the Networker was not able to find any full backups and thus it is changing the current backup to a full ? Please provide the output of savegrp (as suggested by bingo) and also an mminfo output for the client in question for the past 1 week. It might be an issue with a duplicate client id .

This is my backup command now: save -a "ignore-all-missing-system-files=yes", so I should change that to save -c -a "ignore-all-missing-system-files=yes"
I'll add that and report back.. The full takes about 15 hours though.

That's not enough. You must put save -c into backup command. After that, run full backup and then try incremental one.

That did it. I changed the save command and ran a backup on just the C: drive and then a second one and it was incremental. Thanks for the help!
