At the beginning, you need to consider how much you can invest in the solution and what capacities you have for its maintenance . The choice of SQL Server edition is also connected with this . Some of the methods have a wide range of features in the Enterprise edition that are not available or have certain limitations in other editions. You can find a complete overview of the functionalities in individual versions in the official Microsoft documentation . When choosing, it is also important to consider How much downtime you can afford The downtime corresponds to the time the solution will need to recover the data.
In the case of Always On, Mirroring or Replication, it is milliseconds, seconds USA Phone Number List at most . In contrast, the recovery time for Log Shipping is longer and is affected by the selected log copying interval, their size, the configuration of the recovery process or the performance of the secondary server. . How much data you can lose The principle of copying, the choice of synchronous or asynchronous mode (for Always On and Mirroring) or the setting of the interval for creating a copy determines the point in time you return to during the restoration. So how much data will you lose.
With the Always On method and Mirroring in synchronous mode, losses are zero and replication minimizes them. In the case of Log Shipping, the loss of data must be taken into account. Its rate again depends on the set interval. .ocations do you want to copy the data to If you need to have data on only one secondary instance , you can use the Always On or Mirroring method with SQL Standard. To copy to several secondary instances, you will have to use Log Shipping or replication, which do not impose any restrictions on the number of instances. . What are the failover requirements If the requirements of the solution require automatic.
