PAGE compression minimizes the data redundancy in columns in one or more rows on a given page. It uses a proprietary implementation of the LZ78 (Lempel-Ziv) algorithm, storing the redundant data only once on the page and then referencing it from the multiple columns. Note that when you use...
The most important contrast between database mirroring and failover clustering is the level at which each provides its redundancy. Database mirroring provides protection at the database level, whereas clustering provides protection at the server instance level. Another important difference is that in da...
通过T-SQL 创建数据库时,不会强制实施 Azure 策略。 若要在使用 T-SQL 创建数据库时指定数据驻留,请使用 LOCAL 或 ZONE 作为 CREATE DATABASE 语句中 BACKUP_STORAGE_REDUNDANCY 参数的输入。 其他资源 活动 FabCon Vegas 4月1日 7时 - 4月3日 7时 ...

Database mirroring provides complete or almost complete redundancy of the data, depending on whether the operating mode is high-safety or high-performance. For more information, seeOperating Modes, later in this topic. A database mirroring partner running on SQL Server 2008 (10.0.x) Enterprise or...

Employs cost-effective object storage as primary storage. High availability can be achieved through erasure coding technology with only about 150% data redundancy. It also provides high-speed caching capabilities, balancing cost and performance via a multi-tiered storage strategy that separates hot and...
Having extra copies of the database is the tradeoff for ensuring redundancy. An example of an AG that spans multiple data centers is shown below. One primary replica is responsible for keeping all secondary replicas synchronized.Outside of an AG with a cluster type of none, an AG requires ...
