Create MySQL-Backup and cleaner Script (only on one master)The backup script is created on master database. In a redundant system, it must be done on the active master databse. The server creates a rolling backup and deletes backups which are older than 14 days. The cleaner script is also configured right after, to ensure that the two jobs do not run in parallel Note - this script will fail, if the jtel Databases JTELWeb, JTELStats, JTELStats2 and JTELLog are not present. | Warning |

| title | Caution - without Replication |
|---|
| If the setup is without replication, then remove --source-data from the backup script. |
| Warning |
|---|
| title | Caution - Redundancy - Backup only on active DBM |
|---|
| Configure the backup on the active master database on redundant systems, as corruption of the index 'sp_AcdStatisticsLogin_geom3_AcdGroupsID' in the table JTELStats.AcdStatisticsLogin has happened in the past when the backup is made by the secondary database master. |
