One of the most important tasks an administrator has is to set up and maintain storage resources and let users share files across the network. Network Attached Storage (NAS), a hardware/software system designed specifically for network storage, has made the traditional file server storage model all but obsolete. FreeNAS, a NAS server based on FreeBSD, makes implementing NAS simple.With FreeNAS, you can share files among the Windows, Mac OS, Linux, and Unix machines on your network. What's more, FreeNAS provides incremental backups and supports LDAP user authentication, among its many features.
