OK Folks,

A question for tonight:

For traversing through directories and files, what should be the faster:

Walking through the directories and files going depth first or breadth

I would guess that just doing a simple "dd" would be quickest and
minimise HDD head movements... But then that's only useful if you're
near 100% utilisation and you're going to mount the dd copy as an image!

On a related theme:

What utilities do people use for their backups?

See ya later,
