We are in the process of implementing DDR460 restorers in our NetBackup environment. Backups will go to a DDR460 restorer with a three week retention and from there will be duplicated to tape and also replicated to DDR460 restorers at a remote DR site. Right now I have one storage unit created on each of my DDR460s with the maximum concurrent job parameter set to 16 jobs. On my tape based storage units I have "maximum concurrent drives used for backup" set to 6 and "maximum multiplexing per drive" set to 6., so in theory things are roughly equivalent. I have a higher concurrent job number set on my disk storage units, based on DataDomain's recommendation to make up for the fact that we don't multiplex backups to the DDR460. Is anyone else using these and if so do you have any suggestions? So far the technology is working pretty well and now I'm ready to do a full-up test to see how well it handles our entire backup load. Thank You and Happy Holidays Jamie Jamison
