[pve-devel] [PATCH v3 manager 1/3] ui: restore: disallow empty storage selection if it wouldn't work

[Fabian Ebner <f.ebner@proxmox.com>]

Namely, if there is a storage in the backup configuration that's not
available on the current node.

Changes from v2:
    * Improve style.
    * Handle when no storage hint is present correctly.
