I would like to copy my > existing disk to another disk as a backup. The dd utility allows you to make an excact mirror, I think you can even get a bootable mirror disk. But for plain backup purposed, I think it is more efficient to use the rsync utility, this will only transfer differences, so the second backup should be much faster. A third option is to setup a raid. Raid-1 is for disk mirroring (if you have 3 disks you can setup a raid-5 and with four raid-0/1). Raid will keep your mirror updated live - but don't ask me about more details :-) Cheers, Erik -- Ph: +34.666334818 web: http://www.locolomo.org S/MIME Certificate: http://www.locolomo.org/crt/2004071206.crt Subject ID: A9:76:7A:ED:06:95:2B:8D:48:97:CE:F2:3F:42:C8:F2:22:DE:4C:B9 Fingerprint: 4A:E8:63:38:46:F6:9A:5D:B4:DC:29:41:3F:62:D3:0A:73:25:67:C2
