All users (except collaborators) can create Gantt chart snapshots.
There are two possible options to create Gantt chart snapshots:
From the current state – the snapshot will show the current state of the folder, project, or space.
From project history – the created snapshot will show the folder, project, or space state on the chosen date.
The number of snapshots you create for each folder, project, or space is unlimited.
Navigate to the selected folder, project, or space and switch to Gantt Chart.
Click Snapshots on the panel above the timeline.
Select From current state.
Enter a name for the snapshot.
Check (or uncheck) the boxes for the following options as needed:
Share via link
Show assignees names
Click Add.
Navigate to the selected folder, project, or space and switch to Gantt Chart.
Click Snapshots on the panel above the timeline.
Select From project history.
Next:
Select a date for the snapshot.
Enter a name for the snapshot.
Check (or uncheck) the boxes for Share via link and Show assignees names, as necessary.
Click Add.
A Gantt chart snapshot is created. If you checked the Share via link box, a shareable link is generated that you (or others) can use to view your snapshot.
When you create a snapshot a note about it appears in the folder or project Activity Stream.
