> Sir - Whereas Neil, et al, profess that RAID is NOT equal to BACKUP - > Most of us know that tape backup is VERY costly, in several ways, in our No one used the word "tape". Tapes have not been a practical means of backups for many systems for quite some years. Today, for most large systems, the most practical backup solution is hard drive based. Since the OP already has a RAID10 system he has enough or nearly enough drives for a hard drive based backup. Since he is already talking about a remote NAS system, his additional costs can be as low as $0, or at most the cost two or three additional drives. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
