Supposedly you should be able to mount a samba share with -o lfs (large
files) but my own test this very day indicates at least some versions of
samba were silently ignoring this option.  If you do try this, go only
with the latest stable (or latest beta if you have to).

Alternatively you can split the file (using split -b or a host of other
options) to ensure none of your files hit the 2Gb limit.

If you use split -b to split the files, they can be reassembled in order
using cat.

Eg:

split -b bigfile. produces bigfile.aa bigfile.ab bigfil.ac etc.
Notice the use of the "."

Then you can:

cat bigfile.* > restored_bigfile

To get the file back.

This is especially true with tapes.
