Schedule History & Snapshots

Every time a schedule is published to the MP Backend, a snapshot is created automatically. Snapshots are immutable copies of the schedule at a point in time, allowing you to track changes and roll back if needed.

Browsing Snapshots

The History tab shows all snapshots for the active event, sorted newest first. Each entry displays the snapshot date, time and the number of tasks and persons it contains. Click a snapshot to preview it.

Renaming Snapshots

Each snapshot can be given a custom label to make it easier to identify. Click the pencil icon next to a snapshot's version number to enter edit mode, type a name (up to 100 characters), then press the check mark or Enter to save. Press Escape to cancel.

When a label is set, it replaces the default “Version N” heading on the snapshot card, with the version number shown below it. To remove a label, clear the text field and confirm.

Freezing & Unfreezing

Freezing a snapshot protects it from automatic pruning and manual deletion. Click the lock icon on a snapshot card to toggle its frozen state. Frozen snapshots are highlighted with a blue border.

• Frozen snapshots cannot be deleted until they are unfrozen.
• When the snapshot limit is reached, only unfrozen snapshots are pruned — frozen ones are always kept.
• If every snapshot slot is frozen, new publishes will be rejected until at least one snapshot is unfrozen or deleted.

Restoring a Snapshot

Click Restore on a snapshot to make it the active schedule. The current schedule is replaced and a new snapshot is created as a backup before the restore takes effect, so you can always undo the operation.

Deleting Snapshots

Old snapshots can be removed individually to free storage. Click the delete button and confirm in the dialog. The currently active schedule cannot be deleted, and frozen snapshots must be unfrozen first.
