[pve-devel] [PATCH manager 11/11] ui: restore: add live-restore checkbox

Stefan Reiter s.reiter at proxmox.com
Mon Jan 11 12:14:09 CET 2021


Add 'isPBS' parameter for Restore window so we can detect when to show
the 'live-restore' checkbox.

Includes a warning about this feature being experimental for now.
