You can back up an entire Google Drive, or individual files and folders. Optionally, you can choose to back up files that are shared with the Google Drive user.
Files are backed up together with their sharing permissions.
The following items are skipped during a backup:
A shared file, if the user has a commenter or viewer access to the file and the file owner disabled the options to download, print, and copy for commenters and viewers.
The Computers folder (created by the Backup and Sync client)
Limitations
Out of Google-specific file formats, only Google docs, Google sheets, Google slides, and Google Drawings are backed up.
What items can be recovered?
You can recover an entire Google Drive, or any file or folder that was backed up.
You can use search to locate items in a backup, unless the backup is encrypted. Search in encrypted backups is not supported.
You can choose whether to recover the sharing permissions or let the files inherit the permissions from the folder to which they are recovered.
Limitations
Comments in files are not recovered.
Sharing links for files and folders are not recovered.
The read-only Owner settings for shared files (Prevent editors from changing access and adding new people and Disable options to download, print and copy for commenters and viewers) cannot be changed during a recovery.
Ownership of a shared folder cannot be changed during a recovery if the Prevent editors from changing access and adding new people option is enabled for this folder. This setting prevents the Google Drive API from listing the folder permissions. Ownership of the files in the folder is recovered correctly.
