1. Backup entire disk to another disk, verbatim. That is,
dd if=/dev/sdX of=/dev/sdY bs=10M
First, you don't have to waste time figuring out what to back up.
Second, if disk fails, you can just swap the disks, and copy over
only the new files since last dd.
Generally this is a bad idea if your copying a live file system because you
end up with a disk image that is corrupted to some extent.
Yes. I do
telinit 1
mount -o remount,ro /
before running 'dd'.
