./helper-scripts/backup_and_restore.sh restore all /backup/mailcow-backup-2026-08-09.tar.gz
Restore the Mailcow stack from a full backup
restore all unpacks the named backup file and writes maildirs, the database, and configuration back into the stack. It overwrites current data, so verify the file and the target host before running. Follow the script's prompts and restart the stack afterwards.
