[Nottingham] Depth first or breadth first for faster backups?

[Martin]

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
first?

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,

Cheers,
Martin
