A Revit project may be restored to any point in time for which a backup was created. This process supports rolling backward and forward through the snapshots. It is also possible to open a snapshot for comparison without disrupting the project in process.
Restore a Central Project File
For Vault 2014: Log into Autodesk Vault Professional from the Vault ribbon in Revit.
For Vault 2012 and 2013: Log into Autodesk Vault Workgroup, Collaboration, or Professional from the Vault ribbon in Revit.
The opened file should be a local copy of the central file.
Restore a Revit Server Project File
For Vault 2014: Log into Autodesk Vault Professional from the Vault ribbon in Revit.
For Vault 2013 and 2012: Log into Autodesk Vault Workgroup, Collaboration, or Professional from the Vault ribbon in Revit.
The file that opens should be a local copy of the Revit Server file.
