Netbackup 7.1 - High&Low Watermark best practice

Hello guys,

Problem is that sometimes my B2D space ran out of space and the backup will abort. So the question is, if the Settings of my Storage Units look like they should look to work properly:

• Max concurrent Jobs: 4
• Reduce Fragment Size to: 4000 MB
• High water Mark: 90%
• Low Water Mark: 0%
• Enable Temporary Staging Area: yes

My Setup looks like this: 5x B2D each 2 TB for the daily and the weekly setup, 2x B2D each 2 TB for the monthly setup. NetBackup 7.1

For me it seems like the diskspace is running low, before the Staging to the tapes is starting. Is there any changes I can make on the High Water Mark to start the job from the B2D to the tapes earlier or any other improvements, which make sense?

Thanks for a short reply

regards

Marc
