Or use rsync to the 200G disk, assuming you will never have more than 200G on the large disk. That way you need only transfer what has changed. You could set it up to be a dropin. transfer the files, and then run lilo/grub so it can boot from that disk. If your main disk fails just boot from the backup and you are back in business. (You will need to change /etc/fstab to refelect the location of the partitions on the new drive rather than the old. ) > > --- news://freenews.netfront.net/ - complaints: news(a)netfront.net ---

Can someone give me a tar.tgz command line to backup entire system disk ($ooGb nowhere near full) to 200Gb disk? And then a restore command to put it all back, like this: tar.gz the whole 400g disk and store the contents and a restore script on the 200g disk the resore script will partition the new drive and install the files from the tar and then run lilo or grub etc to install the boot sector And the install to 200Gb disk I can handle. This system is working for all I need done right now and need a way to put it all back in case I have to. Only reason I am wiping to install fresh is because the FC13 upgrade left so much FC12 stuff on the disk that yum update won't even work anymore.

Thank you. Slackware?!! Ack! I got my hands full with these rpms, could you imagine me doing the entire distro by tarballs in slackware?
