(just amek sure you are not overwriting the db in the restore cycle, that
you follow the logical sequence:
1. ensure noone connected (e.g. stop server for extremem measure)
2. change name of db
3. start server
4. backup db
5. restore db by creating new db to yet another name
6. rename restored db to original db name
