Allow Backup/Restore to a file of entire site or sections by Site/Subsite Directors or Section editors.
How about giving the Site Director the ability to export the entire website into a compressed zip file, the Subsite Directors the ability to export their entire subsite into a compressed zip file and a section editor the ability to export their entire section into a compressed zip file. Site and Subsite Directors would also be able to just export sections into a compressed zip file.
The opposite option of being able to restore these compressed backups would also be necessary. This would give us the ability to keep archives of our Sites and/or sections in case we need to restore to an early point.
