Today’s Quick Tip focuses on performing Bare Metal Restores with LVM. The value of BMR for disaster recovery is well known, but Linux LVM adds additional complexity to the solution so a more automated solution is key for many of our customers.
Many of our customers that run Linux see value in an automated process for backing up and restoring their LVM configurations, prior to performing a BMR. Starting in CDP 3.18 on Enterprise and Advanced Editions, this Linux LVM BMR process is automated through an on screen wizard. If you are restoring your system partition, you will need to boot your physical or virtual machine from either Live CD or PXE Network Boot. The automated BMR process can then be accessed through the CDP 3.0 web interface by selecting the BMR option for the disk safe associated with your chosen recovery point.
The Bare Metal Restore wizard will guide you through the following steps:
1) Choose the filesystem(s) to be restored
2) Select the host (use the IP address and port of your Live CD or PXE Boot Environment)
3) Define Restore Storage Configuration (this includes partition settings, choosing software RAID devices to restore, and setting up LVM Volume Groups to restore)
4) Map Filesystems
5) Select Restore options
6) Start the Restore process
You can monitor the status of the restore process through the Task History option within CDP 3.0.
