# Backing up Postgresql databases running in Docker container
## Configuration
Please create a configuration file which defines the following variables. 
```
#Where to put the sql dumps
backupFilepath="/var/joplin/postgresql_backup/"
#How many dumps shall be kept
rotationDays=7
#Database settings
dockerContainerName=docker_postgresql 
dbUser=joplin
dbPasswd=123456789
dbName=joplin
```

Pass this configuration file as parameter to the script. To automate the backup job, I recommend to put the script in your crontab: 
``` 
50 2 * * * root /root/scripts/backup/postgresqlBackup/backup_postgresql /root/scripts/backup/postgresqlBackup/joplinBackup.conf
```
