Disk Staging - empty files

[mjdes]

Hi,

We have just found out that our future media server is creating 0byte files in our Disk Staging Unit. The backups are bldingly fast and with no errors.

Has anyone come across this new NBU feature?

We are running Solaris 8 with NBU 5.0 MP3 on all our servers.

When NBU relocates the backups on the DSSU it creates a 0 byte file per backup it has relocated.
This file is used when the cleanup is run on the DSSU where the file indicates that the backup has been relocated and can safely be deleted from the DSSU.

What suffix does the files have?
Are the rest of the filenames the same as the backupfiles?

Thanks for the reply Johnny.

What had actually happened is that I was testing our new media server months ago and had created the dev_null file for testing speed, and forgot to remove the offending file:

/usr/openv/netbackup/bpdm_dev_null

To quote the doc:
bptm will not write its images to disk files (the fragments will be created but the file length will remain 0 and bpdm
will write the image to the bit-bucket (i.e. /dev/null)

Needless to say the system did fly...

Our issue was resolved by removing the file and then the system crashed with hardware issues, which is another story.

Thanks again.
