I am setting up a usb drive to act as a NAS for backing up a couple of computers (Linux and Mac) on my network. I have it running, but I want to make sure I have the correct settings.

I read quite a few Debian and Ubuntu howtos about NFS, but they sometimes offered conflicting information. For the backups, I want to preserve the file permissions, time stamp, etc.

In /etc/exports I have

/media/backup    192.xxx.xxx.0/24(rw,sync,root_squash,no_subtree_check,fsid=0,insecure)

The insecure is for Macs to access on ports other than 1024....at least that is what one article said. It does not mean the connection is insecure....

/etc/fstab for the usb drive

UUID=6997d1c2-5ed7-4f32-9d5e-564cadd7bc6c /media/backup ext4  rw,nodev,noexec,noatime,nodiratime,sync,data=ordered 0  0

Thanks!
