Quemsi is designed with a fundamental principle: your data never leaves your environment. Quemsi operate entirely within your infrastructure, ensuring complete data sovereignty while still providing comfort of a SaaS application.
All backup and restore operations happen within your infrastructure. Our SaaS component manages metadata only - never your actual data.
Backups are stored in your designated storage locations, whether that's local disks, your private cloud, or your own S3 buckets.
Share backups between your development, testing, and production environments - all while keeping data within your organization's boundaries.
You can customize all details about how backups are taken, how they are stored and how they are restored
Quemsi lets you take snapshots of your databases and tag them as you wish. This will create a timeline of your database containing different schema changes and data states from any of your environment at your finger tips. This will allow you to travel in time and across enviroments for a database. For example, you can restore test db state before latest release to your local machine.
Follow this friendly checklist to go from sign-up to your first flow—each step is short, clear, and keeps your data right where you want it.

Quemsi depends on a lightweight agent within your infrastructure that handles all backup and restore operations locally. Our SaaS component only manages metadata like backup tags, schedules, and permissions—never your actual database content. This architecture ensures your data never crosses your network boundary.
Quemsi agent is open source, you can analyze the source code at github and directly build yourself from the source code.
Quemsi supports MySQL initially, more support is on its way like PostgreSQL, SqlServer, SQLite, and more. Our unified API makes it easy to work with multiple database types using the same workflow.
Yes! Our free Solo Developer plan lets you use core features with no time limit without any restriction. Only organizational and enterprise features will be subject to subscription.
Absolutely. Agent will only need one way access to quemsi.com for meta data access. You can keep db level authorization with minimal read-only access. Additionally, you don't have to give db credentials to quemsi.com neither, just inject into agent's environment. Moreover, Quemsi never stores your actual data on our servers, and provides fine-grained access controls for team environments.
