 ## Recover database ##
 
-Assuming you want to restore mytestdb from your backups made on 20190121-1540:
+Assuming you want to restore my-testdb from your backups made on 20211012-0010, define variables:
+```
+DB='my-testdb'
+NEWDB='my-testdb'
+BACKUPDIR='/var/backup/mysql/20211012-0010'
+```
 
+Make sure you have a backup of the current database which will be replaced:
 ```
-DB='mytestdb'
-BACKUPDIR='/var/backup/mysql/20190121-1540'
-sudo mysqldump ${DB} > /root/${DB}-$(date +%Y%m%d).sql
-sudo mysql -e "DROP DATABASE ${DB}"
-sudo mysql -e "CREATE DATABASE ${DB}"
-for table in ${BACKUPDIR}/${DB}/*; do gunzip -c $table | sudo mysql ${DB}; done
+sudo mysqldump ${NEWDB} > /root/${NEWDB}-$(date +%Y%m%d).sql
 ```
+
+And now the actual recovery (Need to be in the same session! Do not enter this in another SSH window / terminal):
+```
+sudo mysql -e 'DROP DATABASE IF EXISTS `'${NEWDB}'`'
+sudo mysql -e 'CREATE DATABASE `'${NEWDB}'`'
+for table in ${BACKUPDIR}/${DB}/*; do gunzip -c $table | sudo mysql ${NEWDB}; done
+```
+
+You can change NEWDB to any other name if you wish to restore to an alternate database name!
