Question

How to restore terminated KVM/XEN VM with Automated Backup?

Answer

KVM
  1. Create new VM from SolusVM with the same resource or larger than the terminated one.
  2. Each VM's will have 3 backup files in the backup server.

    # Backup file: VSERVERID-kvm-kvmID-1.bz
    # VM config file: kvmID.xml
    # LVM config file: config-VSERVERID.dat

  3. Rename the backup files with new vserverID & kvmID

    # newvserverID-kvm-newkvmID-1.bz
    # newkvmID.xml
    # config-newvserver ID.dat

    For example, consider 121 as new ververID & kvm131 as new kvmID

    # 121-kvm-kvm131-1.bz
    # kvm131.xml
    # config-121.dat

  4. Once renamed the files, edit the XML and config.dat files to update the new VM's kvmID and LVM path in it.
  5. Run the restoration script /scripts/ftp-restore on a slave node.
Xen
  1. Create new VM from SolusVM with the same resource or larger than the terminated one.
  2. Each VM's will have 3 backup files in the backup server:

    # Backup file: VSERVERID-xen-vmID-1.bz
    # VM config file: vmID.cfg
    # LVM config file: config-VSERVERID.dat

  3. Rename the backup files with new vserverID & vmID:

    # newvserverID-xen-newvmID-1.bz
    # newvmID.cfg
    # config-newvserver ID.dat

    For example consider 121 as new ververID & vm131 as new vmID:

    # 121-xen-vm131-1.bz
    # vm131.cfg
    # config-121.dat

  4. Once renamed the files, edit the cfg and config.dat files to update the new VM's vmID and LVM path in it.
  5. Run the restoration script /scripts/ftp-restore on a slave node.
