# General Operations

- [Performing Schema Upgrades in Galera Cluster](https://mariadb.com/docs/galera-cluster/galera-management/general-operations/performing-schema-upgrades-in-galera-cluster.md): MariaDB Galera Cluster offers three DDL methods for schema upgrades: Total Order Isolation (the safe blocking default), Rolling Schema Upgrade, and Non-Blocking Operations.
- [Managing Sequences in Galera Cluster](https://mariadb.com/docs/galera-cluster/galera-management/general-operations/managing-sequences-in-galera-cluster.md): Sequences in MariaDB Galera Cluster require INCREMENT BY 0 so the cluster applies an offset-based generation strategy that prevents duplicate values across multiple primary nodes.
- [Backing Up a MariaDB Galera Cluster](https://mariadb.com/docs/galera-cluster/galera-management/general-operations/backing-up-a-mariadb-galera-cluster.md): Consistent backup procedure for MariaDB Galera Cluster: desync a chosen node with wsrep\_desync=ON, run mariadb-backup, then resync the node via Incremental State Transfer.
