Yes there are trade-offs. You will use more tape space similar to what you would with the TDP products, and you are limited to restoring to a NetApp instead of any old Windows server. In many cases, achieving 1/4 the restore time is worth it, especially in cases where you are already exceeding a 24 hour backup window. The shorter backup window also gives you the flexibility to do multiple differentials throughout the day.

Won't you find yourself backing up and keeping identical files over and over again?

I just did this for a customer with a million file CIFS backup taking 8 hours, down to 2.5 hours using NDMP over the network. No change in hardware. ______________________________ John Monahan Consultant Logicalis, Inc. 5500 Wayzata Blvd Suite 315 Golden Valley, MN 55416 Office: 763-417-0552 x109 Mobile: 952-221-6938 Fax: 763-417-0554 [EMAIL PROTECTED] http://www.us.logicalis.com "Haberstroh, Debbie (IT)" <[EMAIL PROTECTED]> Sent by: "ADSM: Dist Stor Manager" <[email protected]> 07/09/2007 03:14 PM Please respond to "ADSM: Dist Stor Manager" <[email protected]> To [email protected] cc Subject netapp backup taking too long I have a netapp share that is being backed up through a Windows 2003 server and is taking 23-25 hours to run. It is on a gigabit network, processing approximately 3.9 million items. Does anyone have any suggestions how to accelerate this job? Max mount points=7, resourceutilization=7, memoryefficientbackup=no. All of the netapp shares back up through this one server but this is the only one that is this large. The sys admin setup several batch jobs that start separately so that more than one backup can run at one time. My TSM server is on AIX 5.3, TSM 5.3 with a 180Gb database, 87.2% utilized so I am hesitant to do anything that will further tax the server. Any ideas how I can back this up faster without stressing the server? Thanks. Debbie Haberstroh Server Administration Northrop Grumman Information Technology Commercial, State & Local (CSL)
