RAID10 could or even should improve performance but its "redundancy factor" will always be 2x. > By the way, I pretend to use an external DB (Amazon RDS) for my > Catalog, so my Storage daemon wouldn't share the same underlying > storage. > Bacula support SQL_ASCII database encoding only. > I hope someone can share some ideas about disk performance. I didn't find enough info about this topic on Internet.
