No, you cannot make a real backup when Outlook is running nor can you make
incremental backups.
If all you care about is the data, then there are some pst-to-pst sync tools
which can create incremental copies of the data but at that time the
pst-file that is being synced to is in use so it cannot be backed up itself
again before it gets disconnected and Outlook restarted.
One such backup tool that can make incremental copies of pst-files is Dunes
Outlook Backup;
