Litestream

Litestream is a standalone disaster recovery tool for SQLite. It runs as a background process and incrementally replicates changes to another file or S3 storage. Litestream only communicates with SQLite through the SQLite API, so it does not corrupt the database.

• Continuous Replication. Streams changes from the SQLite database in real-time to external storage systems. Each modification is captured and sent incrementally, maintaining a permanently updated copy.
• Point-in-Time Recovery. Restores databases to the exact moment of a system failure. Recovers complete transactions without loss of operational data.
• Transparent Integration. Operates as an independent process without requiring modifications to existing application code. Maintains full compatibility with standard SQLite implementations.
• Cloud Replication. Synchronizes data with object storage services like AWS S3, Google Cloud Storage, and Azure Blob Storage. Configures custom endpoints for different providers.
• Cost-Effective Storage. Uses low-cost object storage systems for continuous backup. Eliminates the need for dedicated backup servers for small and medium-sized databases.
• Local File Replication. Duplicates databases to local file systems or NFS mounts. Provides a backup option on your own infrastructure.
• Secure SFTP Transmission. Establishes replication to remote servers using the SSH File Transfer Protocol. Maintains encryption during sensitive data transfer.
• Minimal Configuration. Defines operational parameters using a YAML configuration file. Specifies database paths and replication targets with declarative syntax.
• Operations Monitoring. Provides detailed information about replication status and performance metrics. Monitors synchronization progress and detects connectivity issues.
• Automated Maintenance. Manages retention and rotation of database snapshots according to configured policies. Automatically deletes old copies to optimize space.
• Fast Restore. Initializes replicas from existing snapshots with incremental application of WAL files. Reduces initial synchronization time during restorations.
• Guaranteed Consistency. Preserves transactional integrity by capturing SQLite WAL files. Ensures replicas maintain coherence with the primary database.

Litestream was created by Ben Johnson in 2021. Initial development began as a personal project to solve SQLite replication problems in cloud environments. The tool is written in the Go language, selected for its efficiency in concurrency and binary distribution. The stable 1.0 version was released in June 2022 after testing periods in production applications. The primary maintainer continues to be the original creator, with contributions from external developers via pull requests on GitHub.
