    Problem is the 4GB maximum file size limit of FAT32. As this thread states:

    dd if=/dev/hda | gzip -c | split -b 2000m - system_drive_backup.img.gz.

    will create chunks of 2MB each. Then, to restore:

    cat system_drive_backup.img.gz.* | gzip -dc | dd of=/dev/hda

    Could happen that 1024MB RAM is too few for a virtual machine, and an intensive guest process (more then 2h of elaboration) runs out of memory. But if raising the vm RAM quantity doesn't change a thing, if it runs out of memory when the system has memory, then there is another problem. And here is the solution.
    Basically, adding the following lines

    MemTrimRate=0
    sched.mem.pshare.enable = "FALSE"
    mainMem.useNamedFile = "FALSE"
    prefvmx.minVmMemPct = "100"

    to the virtual machine configuration (mine is ~/vmware/[machine-name]/[machine-name].vmx), will result in faster memory allocation... et voilĂ !
