Message-ID:<1488551@KANSAS-CITY.VA.GOV> From:POLLOCK.STEVEN@kansas-city.va.gov MMDF-Warning: Parse error in original version of preceding line at BRL.MIL To: "POLLOCK,STEVEN L."@kansas-city.va.gov, info-unix%brl.mil@mvb.saic.com Unix Persons, We have up to 2.1 Gig. raw virtual devices used by a database application that we need to back up to 8MM tape drives. The system is running Pyramid OSX and the documentation sez that the only utility available to do this is dd. Coming from a VMS environment we can back up this amount of data in about 1hr-50min. or so. It takes around 6 hours on the pyramid??? 1) Is dd truly the best way to do this? if so: 2) What are the best ibs, obs values that will fit the 2.1 Gig onto the tape unit and speed this up. 3) Is there truly now way to verify the integrity of the data once it has been written to the tape? |>>>>>>>>>>>>>>>>>>>>>>>>>>>>>||<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<| |Steven Pollock || Internet: pollock.steve@kansas-city.va.gov | |VA Medical Center, IRM || Voice: 816-861-4700 x3750 | |4801 Linwood Blvd. || Facsimile: 816-861-8736 | |Kansas City, Missouri 64128 || | |>>>>>>>>>>>>>>>>>>>>>>>>>>>>>||<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<|
