Incidentally, you may want to invest in an external USB hard
drive. They're cheap these days and can hold a lot of data. I've
got one here that's 160 GB. It currently contains a couple of
generations of backup from two computers.
Hmm. I blew off the tiny, hyperexpensive usb drives a couple of
years ago, but haven't looked at them recently. That could work
well. I had been reading up on nfs, thinking about connecting it
to my laptop and using it to back up my data. I also made a quick
try to get ftp working, but didn't succeed immediately, and never
got back to it.
You need another computer to use ftp or nfs. An usb disk is just
another "internal" disk on the system, but physically external. It is
transparent and slower, and very handy.
There are also now storage appliances that implement NFS and / or
SMB/CIFS (accessed via Samba from Unix / Linux systems or via the
built-in file sharing from Windows systems). These are basically
stand-alone boxes with disks (often RAID arrays), a simple server
computer and an Ethernet connection.
They're becoming pretty affordable on a per-gigabyte basis. They're
really only an advantage when you've got multiple computers that need
to access a single storage repository for some reason (shared
publication or media libraries, e.g., or backups). To my knowledge, no
other form of connectivity (FireWire, USB, eSATA, or SCSI) works to
share a device among multiple computers, so you need the network and
server component if you have multiple computers accessing the storage
(and don't want to recable frequently).
I will be moving to a new home soon, and when I do, I think I'm going to
add one of these to my setup, since I now have four separate computers
all in active use whose backups I'd like to unify. Plus, I'd like to
consolidate what is at the moment a very fragmented on-line library of
technical papers, podcasts, ripped CDs, software downloads and other
