A customer currently has 2 networked, external 300GB hard drives. The customer needs for one of the drives to be available for storage to the network. I have this working correctly. It's a drive that's shared and mapped. However, we now need for that drive to backup to the 2nd external drive. The network is a small LAN but it's fairly powerful with Cat6 cable and Gigabit switches. The customer would really like the 2nd external drive to "mirror" the first one, like RAID, but I think we'd be satisfied with an automatic backup. Do you have any suggestions for a solution? I know we could just use normal backup software on one of the computers on the LAN and have ext1 backup to ext2, but are there any other solutions? Thanks!
