I need to find reliable (and cheep) software for cloning Unix Hard Drives. ASAP, please.

just use dd. "info dd" for help. Of course, the two will need to be identical. if you have different physical geometries use cpio piped into another cpio.

the unix command "dd" will do it, from a formatted disk to a formatted disk. run the dd man page for your flavor of unix, but it would be something like #dd if=/dev/hda1 of=/dev/hdb1 bs=1024 this will copy from device /dev/hda1 to device hdb1 1024 bytes at a time. You need to find out how your disks are laid out, and use the device that is linked to the entire disk. dd is a raw file copy command (every thing is a file in unix, including the disk and disk partitions) that copies everything without any processing unless you specify processing (such as converting ibm format to ascii or some such). e-mail me if you need more information.

I am a novice with UNIX, but have a good understanding of DOS. I have an SCO Unix 3.2 server I need to copy. I want to use a larger hard drive and copy both the OS and all existing software to it. I want to start with an unformatted drive. I will put the larger hard drive in another computer and practice with some of the programs that will be copied. I considered using Norton's Ghost, but it will not see UNIX and wants to do a sector by sector copy, using identical drives.... unacceptable. Thanks

Does anyone know if this is built in to Redhat Linux as well?

I have a similar problem. I have network stations that use a compact flash instead of a hard disk. You install a dos formatted CF and set up the station to load & copy the OS from a net server. The problem is the server is miles away and over frame it takes about 4 hours to load the 96Meg flash. I need a way to clone with a laptop using a PCMCIA to CF adapter preferably with win95 or boot the laptop with a unix boot diskette ( if such exists ) I don't know unix... Ghost will see the dos CF card when I first boot but if I remove & reistall, it does not see it anymore.

I have the same problem. but we have no two identical disk. How can I do cloning disk with two diference disk (the second disk larger than the first disk). Could i still use: #dd if=/dev/hda1 of=/dev/hdb1 bs=1024
