It can be helpful for reporting purposes where you do not need the latest data on a secondary database. If the table is empty, data records are entered in the table in the order of the INSERT commands. Therefore, applications can connect to the secondary SQL instance after a failover if the primary SQL Server instance fails. Under asynchronous-commit mode, the primary replica commits transactions without waiting for acknowledgment from asynchronous-commit secondary replicas to harden their transaction logs.

OP wants to see how mirroring compares to the other options and might want to know the failover/failback procedures for each, especially since mirroring doesn't require a re-initialization when failing back like with log shipping. The SQL (Structured Query Language) has several advantages that make it most eminent and most demanded in the market. Up to eight secondary replicas are supported, including one primary replica and four synchronous-commit secondary replicas. 1. The high-level steps of log shipping are as follows: Backup: Take regular transaction log (t-log) backups from the primary server.

You can offload the primary database by moving read-only requests to the secondary AG replica. Today, SQL is most suitable database for each small or large scale companies. Asynchronous-commit mode minimizes transaction latency on the secondary databases but allows them to lag behind the primary databases, making some data loss possible.
