Compress dbexport on the fly

Hi,

I have an old HPUX 10.20 server running Informix 7.23
I need to dump the database to get it off that hardware before it dies.
Unfortunately there is insufficient local diskspace to do so.

I have set up a linux box with sufficient disk onto which I can export the database.

Having configured an NFS link between the two, I ran
dbexport -o /remote
However, the HPUX server has NFS v2 which has a 2Gb file size limit.
Some of the tables being unloaded are over 2Gb in size so the dbexport process terminates when it reaches the first one.

Seems bundle PHNE_25234 would upgrade to NFS v3 but I cannot find it.

My only other idea on how to do this, is to compress the dbexport output on the fly before it is saved to the NFS disk, but I cannot figure out the syntax, or even if it's possible.

Does anyone know how I might achieve this?
Or if it might be possible to transfer the data on the fly another way? By ftp maybe?

Thank you for any help you can offer
