SQLite is a lightweight and widely used relational database management system. It is a self-contained, serverless, and zero-configuration database engine, making it a popular choice for small-scale projects.
One important aspect of working with databases is creating backups to protect against data loss. In this article, we will explore the process of backing up and restoring SQLite databases.

Backing up a SQLite database
Creating regular backups of your SQLite databases is crucial for data integrity and disaster recovery.
To back up a SQLite database, you can simply create a copy of the database file.
$ cp mydatabase.db mydatabase_backup.db
This command creates a new file mydatabase_backup.db, which is an exact copy of the original mydatabase.db file. You can store this backup file in a separate location or on an external storage device to ensure its safety.
Another approach is to use the SQLite command-line tool to create a backup file:
$ sqlite3 mydatabase.db .backup mydatabase_backup.db
The .backup command in SQLite performs an online backup of the database file and saves it as mydatabase_backup.db.
Restoring a SQLite database
Restoring a SQLite database involves replacing the existing database with a backup copy.
To restore a SQLite database, you need to replace the current database file with the backup file.
$ cp mydatabase_backup.db mydatabase.db
This command replaces the original mydatabase.db file with the backup file mydatabase_backup.db, effectively restoring the database.
Alternatively, you can use the SQLite command-line tool to restore the database:
$ sqlite3 mydatabase.db ".restore mydatabase_backup.db"
The .restore command in SQLite replaces the existing database with the backup file specified.
Conclusion
Backing up and restoring SQLite databases is a straightforward process. By creating regular backups, you can ensure the safety and integrity of your data. Remember to store backups in secure locations and verify their integrity periodically.
