borgbackup-docker

Backup folders from environment variables with BorgBackup tool. Forked from azlux/borgbackup-docker

I've create this image to have :

• Simple to use backup
• Easy management with mount and cron, optional (to avoid cron task on the host).
• Easy setup with environnement variables
• MySQL backup included
• All backups encrypted
• External backup from SSH

Environnements variables:

Mandatory:

• BORG_PASSPHRASE - borgbackup passphrase
• FOLDERS_TO_BACKUP_PATH - folder path where you put the Volumes to backup
• BACKUP_PATH - Backup Volume path in distant server
• BORGHOST - SSH host to distant backup
• PORT - SSH port if diffrent from ssh default port

Optionnal

If MySQL or Postgres values are given, mysqldump and/or pg_dumpall will be executed and added to the backup.

• MYSQL_USER - MySQL User (with all table read access)
• MYSQL_PASSWORD - MySQL Password
• MYSQL_HOST - IP or name of the MysQL Host
• POSTGRES_USER - POSTGRES User (with all table read access)
• POSTGRES_PASSWORD - POSTGRES Password
• POSTGRES_HOST - IP or name of the POSTGRES Host
• POSTGRES_VERSION - Version of the postgres database if different from bullseye version
• BACKUP_CRON - Custom CRON time (0 3 * * * :every day at 3AM by default)
• ONESHOT - (true/false) Run the backup without cron (usefull if you have eternal scheduler) - False by default
