During automatic seeding, SQL Server performs a backup over the network for initialization. This process can be slow if the database is very large or the secondary replica is a remote copy. The transaction logs for these databases cannot be truncated during the backup process, so if the busy database initializatio

The is_compression_enabled column of the view reflects the value in automatic seeding when using trace flag 9567 to start compression or not to use compression. Then, when compression is enabled, the value is 0, which is incorrect.

implementation of this principle is called write-time replication. For a snapshot read operation, if the read block is not modified after the snapshot was created, the read operation is redirected to the original volume, and if the read is a block that has been modified, reading the data saved in the snapshot before the original volume changes, simply to read the data in the snapshot, Therefore, the write-time replication mechanism ensures that the data obtained from the read snapshot is consis

Technical backgroundIn SQL Server 2012 and 2014, the only way to initialize a secondary copy of the SQL Server always on availability group is to use Backup, copy, and restore.SQL Server 2016 introduces new features for initializing secondary replicas-automatic seeding (automatic seeding). Automatic seeding use a log stream transfer to stream a backup that uses VDI to a secondary copy of each database that uses the availability group of the configured endpoint. You can use this new feature when

In SQL Server 2017, you can use a different path, but Microsoft recommends that you use the same path when all replicas are hosted on the same platform (for example, Windows or Linux). Cross-platform availability groups have
