You can use the provided script
helper-scripts/backup_and_restore.sh to backup mailcow automatically.
Please do not copy this script to another location.
To run a backup, write "backup" as first parameter and either one or more components to backup as following parameters. You can also use "all" as second parameter to backup all components.
# Syntax: # ./helper-scripts/backup_and_restore.sh backup (vmail|crypt|redis|rspamd|postfix|mysql|all) # Backup all ./helper-scripts/backup_and_restore.sh backup all # Backup vmail, crypt and mysql data ./helper-scripts/backup_and_restore.sh backup vmail crypt mysql
The script will ask you for a backup location. Inside of this location it will create folders in the format "mailcow_DATE". You should not rename those folders to not break the restore process.
To run a backup unattended, define MAILCOW_BACKUP_LOCATION as environment variable before starting the script:
MAILCOW_BACKUP_LOCATION=/opt/backup /opt/mailcow-dockerized/helper-scripts/backup_and_restore.sh backup all
