# Replication and Durability Configuration

Replication and Durability [uses logs and snapshots](https://docs.singlestore.com/db/v9.1/user-and-cluster-administration/high-availability-and-disaster-recovery/transaction-logs-snapshots/usage.md). You can [configure engine variables](https://docs.singlestore.com/db/v9.1/reference/configuration-reference/engine-variables.md) to optimize the use of these logs and snapshots.
