[ovirt-users] Engine Backup/Restore Question

Hi, Currently testing my recovery plan for HE failure. I run a hosted engine, but in the event of some failure of the engine VM i want to be able to quickly restore the engine to a standalone host running independent of Ovirt (in this case a VM running on ESXi). On a dry run I restore the backup onto the ESXi VM and run engine-setup. At this point it fails with an error that I am not in Global Maintenance mode. If I put the cluster into maintenance mode before performing the backup then it works correctly. So is it necessary to do this on every backup? I can find nothing in the documentation detailing this as a requirement? Alternatively it seems I can manually update the ha_global_maintenance column in the vds_statistics table before running engine-setup, but not sure of the implications of doing this. ovirt-4.0.6.3 Thanks, Alan
