Backing Up PS Home Saved Data Utility on a USB Memory Stick?

I have a question for wise, more knowledgeable persons concerning the copying of Home data from the Saved Data Utility (PS3) file onto a USB Drive or Memory Stick. I recently did this so that if my ps3 hardrive was destroyed, or I had to buy a new PS3 for any reason, I could copy onto the new hard-drive my Home data, specifically character settings! I made my avatar's face exactly how I want it a long time ago using a pre-set that does not exist anymore... So if I ever had to remake it from scratch I could not duplicate it. Has anyone ever saved Home Character Settings onto a USB, and uploaded or copied it to a new PS3 and went on Home to find the avatar settings exactly the same? This would be a great relief to me to hear because I am deathly afraid of losing the settings for my avatar's face, which I previously said, is now unattainable due to the fact that Home retired a certain pre-set I used and would need if ever starting over again...
