I am at the point in time, however, where I need to start thinking about a backup system. (Although I could simply ghost the systems, because of not wanting to bring the servers down anymore.) I would like to install a tape drive in one of the systems and simply backup over the network. The question I have, however, relates to the security of using NFS for transferring files over an open network. These machines are not behind a firewall and I don't want to run services that would be pretty vulnerable to hacking attempts. (I am reading Greg Lehey's book - "The Complete FreeBSD" - but he really doesn't get into as much detail as I need to thoroughly research this.) What would the caveats of using NFS to do backups be and is there some way to do NFS using ssh/ssh2? (Can you give me pointers as to where to find the information I need?) Also, offhand, is there a reason why I should consider DAT DDS3 over DDS2? Thanks, SF To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
