[Veritas-bu] NetBackup 7.1 - Windows Slow duplication Tape to Tape
-- How do I check for the -mpx on my bpduplicate? The entire job is run through a GUI interface so I have never seen that option. I first backup to tape and that is multiplexing so lots of jobs run at the same time. Then, I start duplication from the current tapes to new tapes. For some of the server images, it goes pretty quickly and I can actually watch the file size go up as it duplicates. Are you specifying -mpx on your bpduplicate? If you don't, the backups will be "de-multiplexed" on the copies, which mean it will have to go through the original tapes several times to pick out each backup image individually. If you use -mpx, it'll grab all the backup images in one pass and leave them multiplexed on the copies. +-- |This was sent by thomas.ander...@unither-pharma.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
[Veritas-bu] NetBackup 7.1 - Windows Slow duplication Tape to Tape
Hello, I have been pulling my hair out for a couple of weeks on this issue. I first backup to tape and that is multiplexing so lots of jobs run at the same time. Then, I start duplication from the current tapes to new tapes. For some of the server images, it goes pretty quickly and I can actually watch the file size go up as it duplicates. Then, there are server images that take forever, sometimes over two days where there can be five minutes that go by with no progress at all made with the duplication. What could be wrong? What can I look at to debug this issue? Thanks in advance for your expertise. -Tom +-- |This was sent by thomas.ander...@unither-pharma.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +-- ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
