We currently have multiple systems in a data center that are all doing their own backups via backup exec. Because of this, we have 5 separate tape devices and 5 separate tapes that we need to take offsite each day (1 for each system). We would like to restructure this setup so that 1 backup exec server backs up all the systems onto 1 tape and then we only need to take 1 tape offsite.
What i would like to do is have each server backup to our SAN and then have the backup exec machine write all those disk backups to tape. That way we still have our offsite storage requirement met, but we can restore from the san if we ever needed to and dont ever need to restore from tape directly.
My question is, what would be the best way to set this all up? How can the individual servers have access to the san to write their backups and the backup exec server then have access to it to read them if they cant share san targets? Would it make more sense for each server to have its own copy of backup exec then use BE SSO to all write to the same tape device? I really just dont know the best way to set this all up to consolidate the actual backups.
Also, Id like to keep the backup traffic off the lan if possible. The san is a dell ps6000 which is iscsi (if that matters)
