Linux and data storage?

[Sean M McMahon]

You mention  using du -ms to find out how much data you have.  What is the 
difference between that and using df -k .  ?

Hi, Karen:

You don't say how much data you have there? Issue the following command
from your home directory to find out how much data you have:

du -ms .

It will give you a number in megabytes. It may take some time to run.

Now, to your question. You ask whether it would be easy. Well, yes, it
might be, or it might not be.

It's not likely to be pleasant to move copious amounts of data over a
dial up modem connection, but there are easy technologies that can
insure you get a true copy even if it takes some time to accomplish.

I'm thinking of rsync.

And, yes, you are on the right track. Hardware and software can be
replaced. One's work/data files cannot be so readily replaced. So, it is
wise to have one's important data in two physical clocations.

But let's start out by defining how much "a lot" is.
