Use online backup
Prefer the SQLite online backup API to copy while live.
Lock before copying
If file copying, ensure no writes (use WAL checkpoint and locks).
Store securely
Encrypt backups if they contain sensitive data; store off-host copies.
Verify integrity
Run PRAGMA integrity_check on backups periodically.
