Keepit backs up the following standard channel tabs in Microsoft Teams: Website, Planner, Word, Excel, PowerPoint, Visio, PDF, Document Library, OneNote, SharePoint, Stream, Forms, Power BI, Flow, and Azure DevOps.

When a channel is restored, the tabs are returned to the top of the team. The tabs will always be restored even if the entire team, channel, or file (the original file of the content that is embedded in the tab) has been deleted. The only exception is the Azure DevOps tab: If the team was deleted, the tab will not be restored. 

To ensure that embedded content are restored, we recommend you restore the whole team and not just the channel.
