The CDN and version-controlled backup solution for SQLite

Launched October 1st 2025 at sqlrsync.com

SQLRsync is the only cloud-backed SQLite backup and content distribution system that can be run against running SQLite databases:

• No downtime or write locks in backing up your app's database
• No downtime on read-replicas
• After an initial synchronization, subsequent data transfers only move the modified SQLite Pagedata data: so it's fast, efficient, and great for resource-constrained IoT or edge services.

To support homelab and small projects, users that sign up on https://sqlrsync.com/ unlock 100mb of SQLite storage for life. (Some terms and conditions apply.)

• PUSH and PULL rsync of sqlite3 database files to a remote SQLRsync server (defaults to sqlrsync.com)
• Use --subscribe to automatically refresh read-replicas when new data is uploaded
• Creates a -sqlrsync file file neighboring the replicated database which can be shared to PULL down the database elsewhere.
• Stores the PUSH key in ~/.config/sqlrsync/ to allow unattended re-PUSHing of the database (great for a cron job)
• LOCAL Sync (when sqlrsync is provided 2 arguments, both local file paths) allows for a local-only (no server/network use) rsyncing of a running write-node SQLite database to a running read-only SQLite database with no readlocks
• The same mechanism works for PUSH and PULL: the ORIGIN can be a running write-node and the REPLICA can be a running read-only node. It's pretty magical.

• Use --dry to dry-run the command and see what mode it will trigger, and an explanation of what it will do

• On initial upload you can use the --public or --unlisted flag to allow others to view the webpage for your database, and optionally download any version of it.
• Optionally include a commit message (--message or -m) to keep track of your changes

• You can append an @ sign and a version reference to download old versions of the database. For example:

sqlrsync oregon/elections.db           # Pulls down the latest version
sqlrsync oregon/elections.db@1         # Pulls down the first version
sqlrsync oregon/elections.db@latest-2  # Goes backwards 2 versions from the latest
