Bootable backup question

[brn2rnjk1]

I am running Snow Leopard on MacAir (November 2010). I have a WD MyPassport for Mac backup drive. I wanted to make a complete bootable clone. I was using CCC but now I read that it may not always be bootable. I am confused between the WD Software the comes with the dirve (I am assuming it doesn't make a bootable) and CCC and maybe Super.

Are any of these programs able to make a bootable clone and also do incremental backups from time to time.

Thanks

Typically the software that comes on the USB drives is junk. I am using CCC to a USB drive and it's always booted when I tested it.

I would never trust software that comes with an external drive.
Most of the software doesn't play well with OSx.

I use SuperDuper for bootable clones.

I can't speak for Carbon Copy Cloner because I don't use it, but SuperDuper will make a bootable backup. Through its SmartUpdate feature, it will only backup the changes from the previous backup (incremental). It's worth the purchase in my opinion.
