[ale] Best command to copy a mounted filesystem?

[Robert.L.Harris at rdlg.net (Robert L. Harris)]

You want an image of the filesystem/partition or the contents such with
permissions, etc?  If you go with the image you may be sorry, what if
you can't get an identicle replacement disk?  You'll loose out.

Use tar or cpio.  If you don't want a tarball but want to copy /usr to
/mnt/backups/usr then my prefered method is:

"find /usr -mount -print | cpio -pdmu /mnt/backups/usr"
