How can I Mirror a Drive Without RAID

  • rsync -av --delete /srv/dev-disk-by-label-EXT401/ /srv/dev-disk-by-label-EXT402/

    If I enter folders behind the drive labels, does that also work to mirror certain folders? Or is it better to proceed differently?

  • Yes, you can. You can drill down to lower levels and go folder to folder. For example:


    rsync -av /srv/dev-disk-by-label-EXT401/Music/ /srv/dev-disk-by-label-EXT402/Music/


    The above would copy everything under "music" from the source to the destination.


    You might want to leave out the --delete switch until you verify that the first transfer took place. Otherwise, if a mistake is made and the source is blank (a fat finger typo, etc.), the --delete switch will erase the destination.
