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

NAME
DBIx::Class::Storage::DBI::Informix - Base Storage Class for Informix Support DESCRIPTION
This class implements storage-specific support for the Informix RDBMS METHODS
connect_call_datetime_setup Used as: on_connect_call => 'datetime_setup' In connect_info to set the "DATE" and "DATETIME" formats. Sets the following environment variables: GL_DATE="%m/%d/%Y" GL_DATETIME="%Y-%m-%d %H:%M:%S%F5" The "DBDATE" and "DBCENTURY" environment variables are cleared. NOTE: setting the "GL_DATE" environment variable seems to have no effect after the process has started, so the default format is used. The "GL_DATETIME" setting does take effect however. The "DATETIME" data type supports up to 5 digits after the decimal point for second precision, depending on how you have declared your column. The full possible precision is used. The column declaration for a "DATETIME" with maximum precision is: column_name DATETIME YEAR TO FRACTION(5) The "DATE" data type stores the date portion only, and it MUST be declared with: data_type => 'date' in your Result class. You will need the DateTime::Format::Strptime module for inflation to work. AUTHOR
