OS X with SSD&HDD Time Machine Local Snapshot

[haberland.it]

Hey Mac Useres,

I have a MacBook Pro with one SSD for OS X an the programs and a HDD for the dates. Now I want do change the Time Machine directory for the local snapshots.
I want to have the snapshots on my HDD

I know that the TM saves the snapshots in /.Backups

What I already did in the Terminal:
sudo bash
tmutil disablelocal
rsync -ahvHE /.MobileBackups /Volumes/HDD/
rm -rf /Volumes/HDD/.MobileBackups
ln -s /Volumes/HDD/.MobileBackups /.MobileBackups
tmutil enablelocal
tmutil snapshot

Now my question, is this the right way?
