Hi,

We have a Windows Media Server running Netbackup 7.5. There is a staging disk configured in the server using an external storage (HDS). The activities of the staging disk is 100% view in HDS started from around 18:30hrs every Sat to Sun around 11 + hrs. We have checked the backup schedule of all the policies and cleaning schedule of the staging disk and can't find any schedule fall in that period. Any pointer is very much appreciated.

Thanks in advance.

Enable admin log on master and media server as well as bpdm and bptm logs on the media server. 

Any NBU-related activities will be logged in these logs.

1 check which policy use disk staging

2 check the policy schedule, "18:30hrs every Sat to Sun around 11 + hrs"

 if you encount disk staging full situation,you can increase you disk staging space or change disk staging high/low water mark.

Create folders with those names under netbackup\logs.

In master server, I found the following:

netbackup/logs/bptm/060613

netbackup/logs/bptm/060713

netbackup/logs/bptm/060813

 

In media server, found the following:

netbackup/logs/bptm/060613

netbackup/logs/bptm/060713

netbackup/logs/bptm/060713

netbackup/logs/bpdm/060613

netbackup/logs/bpdm/060713

netbackup/logs/bpdm/060713

 

Queries:

- Not sure why the folders had created

- Are the folders and files sufficient to perform the trace, if not, what other folders need to be created

- The staging disk is configured as F drive in media server, how to go about tracing the F drive activities from the logs

NBU write and read activities will be logged in bptm logs.
Disk cleanup will be logged in bpdm.

Duplications/staging is logged in admin log.

On a Windows media server there is obviously the possibility that other monitoring or scanning software (such as AntiVirus scan) will cause I/O activity.

To trace any non-NBU activity, you can use utilities such as 'handle' or 'Diskmon'.

The last weekly anti-virus scan was 6 Jun 13 8:33pm. Correct me this can be ruled out since the F drive activities in media server is on 7 to 8 Jun.

From the server manager, the system drive is drive1 and drive F is drive0. Downloaded Diskmon but seem only show drive1, not sure whether it also monitor the F drive (drive0)?

What I was trying to say:

NBU activity will be logged in the logs that I have mentioned.

Any non-NBU activity will need OS or 3rd-party tools.

If Handle and/or Diskmon does not help, speak to your Windows sysadmin to look for tools that will help you.

Processes that run on a media server when backups are running is bptm and bpbrm..
