    hi

    Is it possible to backup FreeBSD using G4L and should I choose lzop for the compression?

      hi
      Is it possible to backup FreeBSD using G4L and should I choose lzop
      for the compression?

      As long as it is a system that can boot the g4l it should be able to back it up
      in raw mode. It can even be used to back up macs that use the intel chip, but
      not the older motoral ones.

      Lzop is the default compression for reasons of speed. In test long ago, I
      found that lzop was about twice as fast as gzip, and 6 times faster than bzip
      to create the images. The difference in image size was about 10% larger for
      the lzop compared to gzip. The other issue was cpu load. With lzop it would
      only put a load of about 30% on the cpu, whereas gzip would generally show
      about 60% cpu use. With lzop there was always cpu % left availabe, but with
      dd, ncftp, and gzip running it would max out the cpu.
