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. Append
--delete-days n to delete backups older than n days.
# Syntax: # ./helper-scripts/backup_and_restore.sh backup (vmail|crypt|redis|rspamd|postfix|mysql|all|--delete-days) # Backup all, delete backups older than 3 days ./helper-scripts/backup_and_restore.sh backup all --delete-days 3 # Backup vmail, crypt and mysql data, delete backups older than 30 days ./helper-scripts/backup_and_restore.sh backup vmail crypt mysql --delete-days 30 # Backup vmail ./helper-scripts/backup_and_restore.sh backup vmail
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
