    Abstract: A high availability distributed, deduplicated storage system according to certain embodiments is arranged to include multiple deduplication database media agents. The deduplication database media agents store signatures of data blocks stored in secondary storage. In addition, the deduplication database media agents are configured as failover deduplication database media agents in the event that one of the deduplication database media agents becomes unavailable.

    Abstract translation: 根据某些实施例的高可用性分布式，重复数据消除的存储系统被布置为包括多个重复数据删除数据库媒体代理。 重复数据删除数据库媒体代理存储存储在辅助存储中的数据块的签名。 此外，如果重复数据删除数据库媒体代理之一变得不可用，则将重复数据删除数据库媒体代理配置为故障转移重复数据删除数据库媒体代理。

    Abstract: According to certain aspects, a method can include receiving an indication that a restoration of a deduplication database using a secondary copy of a file associated with a secondary copy job is complete; retrieving a first data fingerprint from a data storage database, wherein the first data fingerprint is associated with the secondary copy job used to restore the deduplication database; retrieving a second data fingerprint from a deduplication database media agent, wherein the second data fingerprint is associated with the secondary copy job used to restore the deduplication database; comparing the first data fingerprint with the second data fingerprint to determine whether the first data fingerprint and the second data fingerprint match; and transmitting an instruction to the deduplication database media agent to rebuild the restored deduplication database in response to a determination that the first data fingerprint and the second data fingerprint do not match.
