We use dump and restore and have a firewire drive on our backup server. e.g. either "push" or "pull" the dump to your backup server #!/bin/sh #push a backup image to the server backupserver.example.com #and place the gzip'd file in the path /backups/server /sbin/dump -0uanf - / |gzip -5 | ssh -c blowfish backupuser@backupserver.example.com dd of=3D/backups/server/dump-root-l0.gz /sbin/dump -0uanf - /usr |gzip -5 | ssh -c blowfish backupuser@backupserver.example.com dd of=3D/backups/server/dump-usr-l0.gz /sbin/dump -0uanf - /var |gzip -5 | ssh -c blowfish backupuser@backupserver.example.com dd of=3D/backups/server/dump-var-l0.gz To restore, plug in your new fresh drive /stand/sysinstall fdisk it, add the bootloader (all part of the fdisk process) then use disklabel to partition to your liking either as big or big enough to hold your data mount the new drive under something like /mnt-root /mnt-usr /mnt-var cd /mnt-root zcar /backups/server/dump-root-l0.gz | restore -f - ....should work or if it does not take it from the pipe, gzip -d the file first and then cd /mnt-root and restore -f /backups/server/dump-root-l0 ---Mike On Thu, 11 Dec 2003 08:59:47 +0100, in sentex.lists.freebsd.isp you wrote: >Hi > >I hope to find the right "gurus" here for my question. > >I have a server (A) which has a 9 GB SCSI boot disk.
