It really depends on what you're trying to do. If you want a logical copy, you can use the ol' tar trick:
tar --preserve --one-file-system -cf - | (cd /mountpoint ; tar --preserve -xf -) If you want a physical copy, you can do: mount /mountpoint-of-old-disk -oremount,ro dd if=/dev/old-disk-dev of=/dev/new-disk-dev This will probably mess up your patrition table on the new disk, you'll have a partitioning scheme the same as the old drive, but it's good for backup. If you are worried about a disk failure, you can leave both disks in the machine and run them in RAID-1 mode using raidtoold or mdadm. There's a procedure to be followed for adding another disk to an existing one and creating a mirrored pair without destroying your current copy, at: http://linas.org/linux/Software-RAID/Software-RAID-3.html (read Q 10 and the reply) http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO-4.html#ss4.14 - older but still true The mdadm tools are better and newer. Some of the stuff I have linked to refers to raidtools which are older. -- Arik -----Original Message----- From: Amir Spivak [mailto:[EMAIL PROTECTED] Sent: Monday, December 22, 2003 11:49 AM To: [EMAIL PROTECTED] Subject: Hard Disk mirroring Hi, I have a server which i want to copy in case of a HD failure, the way i want to do it is just copying all its contents to a new HD that i will mount on the server, after mounting, i want a utility that will mirror entire HD to it in the simplest way possible, thx. ********************************************************************** This email and attachments have been scanned for potential proprietary or sensitive information leakage.
