Thanks for the PR @chengxicx . There was already a PR open for this at #666, what is different about this PR? Restoring backups is such a massive thing that I'm not sure how much I want to automate it :-) I don't know if there will be primary key issues with any things like audio files, images, etc. This may require a lot of work. |

Adds a complete end-to-end backup and restore workflow:
One-click backup trigger available on the Settings page; archives include the database, configuration files, and book library data
Supports rolling back the system state from any historical backup snapshot
Preserves all user custom preferences (backup directory path, MeCab binary path, etc.) during restoration, preventing overwrites from outdated configs stored in backups
Implements SQLite connection pool reset logic to maintain valid database connections after swapping database files during restore
