When do I use Page Set Sync vs making a copy or a User backup?

Scenario 2

Tommy uses TD Snap to work on his literacy skills. His teacher and speech-language pathologist (SLP) want his Page Set on their iPads, so that they can model building sentences when they work with him. 
Best Option: Sync and Share

 
Since Tommy’s page is already Synced (scenario 1), his Page Set can quickly be shared with his teacher and SLP by simply entering their MyTD username in the Share a Page Set popup in TD Snap. They will receive an email that his Page Set has been shared with them. They can then download the Page Set and Sync it to get changes that have been made by others or pass on changes they make while working with Tommy.
The challenge here is that everyone needs to communicate about who is making changes and when, so two people are not making changes to the same page(s) at the same time. The Synced Page Set on MyTD will contain the change in the last Page Set to be Synced, overwriting any previous changes from prior Syncs.
Note: if someone does a Sync and overwrites important changes, they can be recovered through the Saved Versions drop-down in the Sync popup (Top bar). The last 10 Syncs will be available there.

Mackenzie is using TD Snap at home with her iPad to communicate with her family and friends. Her parents have customized a large amount of the content. They are worried about losing all that work, so they want to archive a copy in case something happens to her iPad.
Best Option: Create a user backup

 
All of Mackenzie’s Page Sets and User setting are part of her user. TD Snap gives you the option to create a complete backup of the user, which can be used to restore a repaired device or transition to new device. If her user backup is restored on a second device, she will have an exact copy of her Page Sets and User Settings. Her Page Set could even be Synced with the original on her iPad so both devices can always be up to date.

The teachers at the local early learning center created a new Page Set template designed to support various classroom activities. They want to make the Page Set available to other teachers in the school, so those teachers can modify it for their individual classrooms.
Best Option: Sync and Share Copy

Any Synced Page Set can be shared as an un-Synced copy suitable for independent customization. This can be done by using the Share a copy option in the Page Set editing panel (share icon for your Page Set).
