Setting up backup on the DNS-323

Here's a quick and dirty way of doing backups from Volume_1 (aka HD_a2) to Volume_2 (aka HD_b2) on a nightly basis. In summary, here is what you need to do:
  1. Install and configure fonz's fun_plug. (look here for details)
  2. Grab and install the rysnc addon package for fonz's fun_plug.
  3. Define a rsync job to run on a nightly basis at 2:05am. The crontab line will look like this: 5 2 * * * /mnt/HD_a2/fun_plug.d/bin/rsync -rlptDv --delete /mnt/HD_a2 /mnt/HD_b2 >/mnt/HD_a2/fun_plug.d/log/rsync.last.log 2>&1
  4. Create a script in the start folder (i.e. /mnt/HD_a2/fun_plug.d/start) to add the above into the crontab every time you boot the box. (Remember to set execute permission for the script to auto run on the next boot.)
