Simple DB Backup

Safe, modern database backups for WordPress — create, schedule, download, restore, optimize and repair, from a clean WordPress admin screen.

Simple DB Backup is a modern, security-hardened database tool inspired by the classic WP-DBManager. It is an independent reimplementation that keeps the genuinely useful, non-destructive tooling and leaves out everything that made the original risky.

Features

• Create database backups with mysqldump, optionally gzip-compressed
• Independent WP-Cron schedules for automatic backup, optimize and repair
• Download, restore and delete backups from the admin
• Read-only database statistics

Security

• Credentials passed via a temporary --defaults-extra-file (chmod 0600), never on the command line — no password leak in the process list.
• Processes launched without a shell (no command injection).
• Backup filenames confined to the managed directory (basename() + realpath() + extension allowlist) — no path-traversal download/delete.
• Backups stored in an unguessable wp-content/uploads/ subdirectory with .htaccess / web.config / index guards and restrictive permissions. Optionally relocatable to any absolute path (validated, hardened, with a warning if it sits inside the web root).
• Multisite: restricted to network administrators.

Deliberately omitted (features WP-DBManager had): empty/drop tables, arbitrary SQL execution, emailing backups, and global admin notices.

Requirements

• WordPress 6.5+
• PHP 8.1+
• mysqldump / mysql binaries and PHP proc_open (for backup/restore)

Installation

Install the zip from a GitHub Release via Plugins → Add New → Upload Plugin, activate, then set the binary paths under DB Backup → Settings.
