Itanium RHEL5 system backup / restore from scratch
Hi all,
I wonder which would be the correct procedure to backup an Itanium server (lets say a rx7640) using dump (to local tape) and more important the procedure to restore this backup to a new formated disk (disaster recovery situation). I summarise the steps I would follow.
Backup: 1) make a note of the partitions of the system disk and /etc/fstab 2) make a tar backup of the /boot/efi partition. 3) Boot from RHEL5 1st CD in rescue mode without mounting the underlying OS (skip choice). 4) dump of / (root) partition to local tape.
Restore to a formated disk:
1) use of smart setup to recreate /boot/efi partition an HP Offline diagnostics partition (and copy Offline diagnostics to that partition) 1) Boot from RHEL5 1st CD in rescue mode (with network configured). 2) Recreate the / (root partition) and swap partitions using parted. 3) Label the / (root) partition (using e2label) and the swap partition (with mkswap -L) using the info provided from /etc/fstab. 4) ftp the tar backup to the /boot/efi partition and restore it. 5) mount root partition and restore / (root) partition from tape backup. 6) reboot
Is there something missing from the above procedures. Please advise.

Let's re-phrase my question. Is there anyone that restored an Itanium server from scratch just using a dump backup of the root filesystem? I mean without even doing a minimum installation before the restore (just partitions recreation on new disk and restore). And if true what are the correct steps?

Hi Silju,
Thank you for the advice. I've heard about mondo rescue but I would prefer to use OS utilities (linux rescue mode and dump/restore) for this purpose (disaster recovery of OS).
