The backups do run on a separate VLAN, but I am not certain that Jumbo 
frames are enabled. Still new to Netapp and will investigate qtrees.

Re: [Networker] Long NDMP Backups






You could backup the volumes on separate days, but since you are already 
doing a DSA backup (backing up via the net rather than direct backup), you 
are already getting the advantages of parallelization and variable block 
lengths. To increase the parallelization, you can change to backing up by 
qtree's rather than volumes. Each qtree will be parallelized with the 
backup. Also, the delay in the nsrdump is reduced since it has to walk a 
smaller part of the volume.

Also, do you have the backups on a separate network? We have found by 
separating out the NetApp backups to a different nic on the NetApps and 
different NICs on the backup server and running Jumbo frames, the backup 
was greatly increased (and lowed the CPU overhead on the backup server).

Subject: [Networker] Long NDMP Backups

My last backup of ~3TB of data on a NETAPP filer took about 12 hours. I'm 
on a private vlan with an LTO3 tape SCSI conncected to my Networker 
server. Is that an acceptable time to accomplish a backup? I thought I saw 
on one of the postings that I could split up my volumes and backup each up 
on a separate schedule??? Am I halucinating?
ex. 
/vol/vol1 Full on Day1
/vol/vol2 Full on Day2
/vol/vol3 Full on Day3

You get the picture...
