The OpenSTorage interface, a new way to use your Data Domain boxes (and other boxes that support it) with NetBackup. It's not NFS or CIFS, it is its own transport. It is also not VTL. Think of it as a more intelligent DSU. In the case of DD & Quantum, the data is sent over IP. With Falconstor, the data is sent over Fibre Channel. With DD boxes (which is what started this conversation), the first improvement you'll get simply by switching from NFS/CIFS to OST is a significant increase in performance. With all systems that support OST, you also get what NBU calls "optimized deduplication," where NBU tells one OST device to copy a given backup to another OST device. The OST device (in this case, the DD box) will use dedupe and replication to get the data there. Once there, it informs NBU. Now NBU knows about both copies, just as if it had duplicated it via bpduplicate. Nice, huh? The nice thing that OST is supposed to support is tape-out functionality, where an OST device can copy it's backup to tapes and tell NBU which tapes got which backups. Again, just as if it NBU did the copy. Here's my blog post about OST: http://www.backupcentral.com/content/view/198/47/ +---------------------------------------------------------------------- |This was sent by wcplis...@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
