Hi Hugh:

  This is something we we in the midst of trying out.
  We wanted to first determine if we were looking at a size limitation which it appears as though we are.

  I will try to split up the backups and report back.

 - Thanks,
        Kevin

Re: Backing up  a QNX 4.25G hard drive





2GB is the file size limit under QNX4, so if you create a file that is
less than 2GB on the USB drive, is it readable on another machine?
