Hello Sandesh We have 4 DataDomain systems two at each of our main sites. We replicate between both sites. We are using the OST option with Storage Lifecycle Policies. we are currently running Netbackup 6.5.6. It is running very well. We do not use the VTL option. The only problem is that we have occasional "83" errors on some of the SLP policies due to a timing problem when connecting to the DD unit with the OST plug in, however when the policy automatically re-runs is is fine, we do not have any missing replicated copies. We are awaiting a fix from DataDomain which should take care of the problem. I would recommend this option instead of VTL.

I've a couple of questions about it for the experts. Plan is to have a DD appliance in 1 location and replicate data to another DD appliance in another location. Plan is also to generate a tape copy for long term archival at primary location. 1.OST & VTL are both being discussed. Which option is most favorable in the industry? Are there any specific advantages that can make or break things? 2.VTL supports LTO3 drives at the most. Does this mean that we need to have LTO3 physical tape drives for duplicate copy or will LTO5 drives work? Thanks in advance. +---------------------------------------------------------------------- |This was sent by sandesh....@gmail.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 This Email message and any attachment may contain information that is proprietary, legally privileged, confidential and/or subject to copyright belonging to Pepco Holdings, Inc. or its affiliates ("PHI").
