The Google Drive API v2 Drive.revisions.update method allows the setting of a pinned parameter so that the particular revision is never automatically purged. However as the documentation says, this does not apply for Google Docs. How can we pin a revision so it is never deleted? I have an app that depends on tracking and retreiving certain revisions at a later point in time.
Any suggestions on how this can be done?
Google docs (as well as all native google formats like spreadsheet) does NOT get any revisions deleted automatically, thus there is no need to pin revisions.
If you were referring to .doc, those aren't Google docs.
I couldn't find a reference inside the documentation, but I did find an official reference in their marketing page: https://apps.google.com/intx/en/products/docs/ says:
Unlimited revision history
Track changes made to your documents and undo anything you choose. Previous versions are kept indefinitely and they don't count toward your storage.
