Alternatives

Overview

Litestream aims to provide a balance between durability and operational complexity by batching changes into one-second windows and asynchronously backing those changes up to external storage. This improves write performance at the expense of having a small window of data loss in the event of a catastrophic failure.

However, this tradeoff may not make sense for all applications. This page lists alternative approaches and when they might be appropriate.

Periodic SQLite backups

Sometimes Litestream can be overkill for projects with a small database that do not have high durability requirements. In these cases, it may be more appropriate to simply back up your database daily or hourly. This approach can also be used in conjunction with Litestream as a fallback.

Please see our guide to running a cron-based backup strategy.

Raft-based consensus

You can achieve higher durability guarantees by running a cluster of nodes that perform Raft-based consensus for every write. This approach trades higher durability for lower write throughput as each write needs to be committed to a quorum of nodes in the cluster.

Two projects exist that implement Raft-based consensus over SQLite:

Virtual File System (VFS)-based approaches

Litestream works as a separate process so that it can separate operational concerns from application concerns. However, there are replication solutions that allow you to compile replication into your application using the SQLite virtual file system:

Other databases

Client/server databases such as Postgres and MySQL provide additional replication options such as synchronous replication. These can be also be good choices over SQLite although these typically have more operational complexity.
