    Abstract: Rather than relying on pre-defined scheduling of secondary copy operations such as backup jobs, the illustrative opportunistic approach initiates secondary copy operations based on changing operational conditions in a storage management system. An adaptive backup readiness score is based on a number of backup-readiness operational factors. An illustrative enhanced data agent which is associated with the target database application (or other executable component) may monitor the operational factors and determine the backup readiness score based on weights assigned to the respective operational factors. The enhanced data agent may evaluate recent backup jobs to determine which of the operational factors that contributed to the backup readiness score may have been most relevant. Based on the most-relevant analysis, the enhanced data agent may adapt the weights assigned to the monitored operational factors, so that the backup readiness score may be more suitable and responsive to ongoing operational conditions in the system.

    Abstract: A data storage system, according to certain aspects, automatically backs up source data when the replication data is faulty. For instance, the system performs data backup using replication data rather than source data to reduce the processing load on the source system. The backup data is then associated with the source data as if the backup had been performed on the source data. If the replication system fails, then backing up replication data results in backup data that does not accurately reflect the source data. When permitted by the user system configuration, the system automatically backs up source data when replication has failed.

    Abstract translation: 根据某些方面，数据存储系统在复制数据有故障时自动备份源数据。 例如，系统使用复制数据而不是源数据执行数据备份，以减少源系统上的处理负载。 然后将备份数据与源数据相关联，就好像对源数据执行了备份。 如果复制系统失败，则备份复制数据会导致不能准确反映源数据的备份数据。 当用户系统配置允许时，系统在复制失败时自动备份源数据。

    Abstract: A method and system for utilizing snapshots to provide copies of a database or other application or large data structure to computing devices receives a request for access to a copy of a database, and performs a snapshot of a storage volume containing the requested database. The system then clones the snapshot and mounts the snapshot to a computing device, thus enabling the computing device to access a copy of the database. In some examples, the system automatically updates copies of a database on a scheduled basis (e.g., daily or weekly basis) to refresh a database regularly.

    Abstract: The data storage system according to certain aspects can implement table level database restore. Table level database restore may refer to restoring a database table and its related data without restoring the entire database. The data storage system may use table metadata index to implement table level restore. A table metadata index may be created for each table, e.g., during a backup of the database. The table metadata index for a table can include any type of information for restoring the table and its related data. Some examples of the type of information included in the table metadata index include the following: container for the table, table backup location, system data, table index, table relationships, etc. Table metadata index can make the restoring of tables fast and efficient by packaging information that can be used to restore a table and its related data in an easily accessible manner.
