[pve-devel] [PATCH v2 manager 1/3] fix #1594: add "Run now" button to cluster backup page

[Stefan Reiter]

To allow masking to be correctly handled, we use a counter variable to
keep the mask visible until all tasks have been completed. Any errors
that occurred will be displayed in a consolidated message box.

Includes a "confirm" dialog to not accidentally run a potentially large backup
job.

Curiously, the "pve-cluster-backup" data model seems to have been broken
entirely.  I'm not sure how it was working before, but the changes in
this patch need it fixed, so include that as well (use "mode" instead of
individual flags + "compress" is not a boolean).
