Is there any way to add more backup streams for a single backup job? I woulkd rather do that instead of multiple dags

What is the disk latency before, during, and after the backup? If your latency is high before the backup starts, then it’s going to be terrible during the backup and lead to poor performance. -Jonathan From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Brian Marsee Sent: Sunday, October 23, 2011 4:54 PM To: 'len.bo...@sas.com'; 'veritas-bu@mailman.eng.auburn.edu' Subject: Re: [Veritas-bu] BackupExec 2010 R2 Job Rate Very Slow Hi Len, Using exchange 2010 on windows 2008 R2 with 1 active dag and 1 passive dag. Currently backing up the active dag to a CIFS share on the Backupexec server which is mounted from an EMC Data Domain appliance (Deduplicated disk array). Exchange servers are virtualized with VMware vsphere 4.1. Performance is dog slow for these backups.

Which exchange server are you using. Are you writing to a backup folder or to a virtual tape drive This may not be the only or the best method. If to a backup to disk folder and you have multiple daq’s or storage groups then you can put them in different jobs. If you allow multiple jobs to write to the backup to disk folder then you can have multiple jobs running at the same time. len From: veritas-bu-boun...@mailman.eng.auburn.edu [mailto:veritas-bu-boun...@mailman.eng.auburn.edu] On Behalf Of Brian Marsee Sent: Sunday, October 23, 2011 4:22 PM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] BackupExec 2010 R2 Job Rate Very Slow Hello All, Currently running backexec 2010 R2 and the backups are writing to Data Domain. The job rate and performance is extremely slow and backups for a 1TB exchange server are running extremely long (20+ hours)! I can see from the data domain auto support that backupexec is only pushing a single backup stream. Is there a way to increase the number of backup streams in backupexec to get better performance? I have ensured that the speed and duplex settings on all servers, switches, and data domain are hard coded to 1gb full duplex. Is there something else that could be related to the very slow performance? Thank You, Brian
