Encrypted, deduplicated backups for MySQL and MariaDB databases

Protect your MySQL and MariaDB databases against data loss, accidental deletion, and misconfiguration. Plakar provides encrypted, deduplicated snapshots using the backup tools MySQL and MariaDB already ship with.

MySQL and MariaDB are reliable, until something goes wrong

MySQL and MariaDB power some of the most widely deployed applications in the world. They handle data integrity well at the storage level, but they have no built-in protection against the most common causes of data loss: a bad migration, a dropped table, or compromised credentials. Plakar integrates with mysqldump and mariadb-dump which are the backup tools MySQL and MariaDB already ship with, adding encryption, deduplication, and snapshot management on top of the standard SQL dump format.

Why protecting MySQL and MariaDB data matters

MySQL and MariaDB handle storage-level durability well, but they offer no protection against the most common causes of real data loss:

  • Accidental deletion: A DROP TABLE, a bad migration, or a DELETE without a WHERE clause wipes data instantly. Replication ensures every replica reflects the same mistake just as quickly.
  • Corruption: A failed upgrade, a misbehaving plugin, or a storage fault can corrupt a database in ways that are not immediately visible and this can also be replicated across replicas.
  • No rollback: Without snapshots, there is no way to return to an earlier known-good state. By the time a problem is noticed, the damage may already be replicated everywhere.

For production databases, a backup stored independently of the database server is not optional.

What happens when a database is compromised?

MySQL and MariaDB access is controlled by user accounts and connection credentials. If those credentials are leaked or permissions are misconfigured:

  • Total loss: An attacker with sufficient privileges can drop databases or truncate tables through standard SQL. Automated scripts can do this in seconds across every database on the server.
  • Ransomware: Malicious actors can exfiltrate data and then delete or encrypt the originals, leaving no clean copy to recover from.
  • No recovery path: Without an independent backup stored outside the database server, there is nothing to restore from.

Plakar mitigates these risks by storing snapshots in an isolated Kloset, encrypted end-to-end and independent of the database server itself.

How Plakar protects your databases

Plakar integrates with MySQL and MariaDB through their native dump tools (mysqldump and mariadb-dump).

Both single-database and full-server backups are supported. A single-database backup captures the schema, data, routines, triggers, and events for one database. A full-server backup captures everything across all databases in a single snapshot.

Backups can be stored on any supported backend: local storage, S3-compatible object storage, SFTP, or cold storage. Because Plakar snapshots are immutable and end-to-end encrypted, they remain intact even if the database server or its credentials are compromised.

Security by design

Reduce your attack surface by keeping encryption keys out of storage. With true end-to-end encryption, your data is protected before it leaves the source and remains unreadable even to your storage provider.

  • End-to-end encryption with modern crypto (no compromise on "at-rest/in-transit")
  • Immutable snapshots with verifiable integrity
  • Tamper-proof metadata and audit logs
  • Zero-trust-friendly architecture
"You don’t have to trust your storage provider."
