The Local Backup plugin automates the process of creating local backups for your Obsidian vault. It allows users to schedule backups on startup or at regular intervals, customize the output path, and even integrate with external file archivers like 7-Zip, WinRAR, and Bandizip for large vaults. The plugin also features retry capabilities in case of failures, and it enables users to create specific backup files on-demand. This ensures that your Obsidian vault is protected against data loss and provides peace of mind for long-term use.
