Backup & ExportIntermediate
1Question 1 of 1
bashHow do you backup and export an active SQLite database safely?
Explanation & Concept
Simply copying an active SQLite file while writers are active can lead to corrupted backup files. SQLite provides the **Online Backup API** (and the `.backup` CLI command) to generate consistent snapshot copies while concurrent reads and writes continue uninterrupted.
Code Example
bash
# Safe command-line backup of a live SQLite database
sqlite3 production.db ".backup 'backup_copy.db'"
# Export complete database schema and data as plain SQL text
sqlite3 production.db .dump > full_dump.sqlHow It Works & Key Takeaways
The `.backup` command coordinates with SQLite's internal lock pager, ensuring that active WAL writes do not result in torn or half-written pages.
