Have you deleted a document and you need to restore the document in NetDocuments?
A backup is done once every 24 hours and usually overnight. Each document will have up to 30 indivudal backups points to be available which represents one day of edits.
So assume the following two secnarios
A document is edidted every day then there may be up to 30 days of available backups to restore to.
A document is edited once a month then there may be up to 30 months of available backups to restore to
Note that you can not roll back deleted documents, but deleted documents can be undeleted by searching for them in the Advance search page.
Who can roll back a document?

Where can the cabinet administrator do this?
