I just recently wrote a custom script that "mirrors" two drives each night. It starts by 'dd'ing the mbr and the /boot partition, then mounting the "/" and "/var" partions on the secondary drive, use mirrordir to sync up the files, then unmount everything on the second drive when finished. Useing dd for the mbr and /boot partition keeps lilo synced up on both drives, and makes sure that the kernel is in the same physical place on the second drive. Of course this requires that boths drives are physically the same. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= O- Ken Bowley/SysAdminmailto:[EMAIL PROTECTED] Viking Systems, Inc. http://www.vikingsystems.com -=-=-=-=-=[Sair Linux and GNU Certified Professional]=-=-=-=-=- It wasn't exactly a divorce -- I was traded. -- Tim Conway

Then you can better use named pipes, then you won't need tempspace mkfifo /tmp/somenamedpipe on : tar -zxvf /tmp/somenamedpipe and in another shell, while the above is running... on : tar -zcvf /tmp/somenamedpipe You can also use the tools 'mirrordir' and 'copydir', they are in the same package, and they copy (or copy with delete) one directory tree to another, in a minimal way (Compare timestamps, don't copy if even..)

Temporarily, or as a permanent solution? Temporarily you can just prepare the new drive with the same partitioning scheme (size not usually important) and mount each one, then extract your tarballs to the new targets. For a permanent setup, you can use software RAID mirroring. I have experience with hardware RAID, but not software driven.

Problems with my HD
Hi all. I´m having some phisical problems with my hard drive. How do I transfer all my data from a hd to another. I wish to duplicate the hd and then change it. How is the easy way to do it? (sorry for my english). Is there a way to work with two hard drives, something like master and slave, but the slave been a mirror of the master? Just to increase security, if the master fails the slave could substitute the master. thanks in advance
