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.
Claims20
A method of performing data backup in a data storage system, the method comprising:
- receiving instructions to back up source data stored in one or more primary storage devices associated with a client computing device;
- automatically determining with one or more processors whether replication data stored in one or more replication storage devices is an accurate replication of the source data;
- providing a notification that the replication data is faulty when the replication data is inaccurate;
- when the replication data is inaccurate and a user configuration permits backup from the source data, automatically copying with one or more processors the source data to one or more secondary storage devices to create a secondary copy;
- and
- associating the secondary copy with the source data.
A system to create secondary copies of data associated with user computing devices, the system comprising:
- computer hardware including one or more computer processors;
- and
- computer-readable storage comprising computer-readable instructions that, when executed by the one or more processors, cause the computer hardware to perform operations defined by the computer-readable instructions, the computer-readable instructions configured to:
- receive instructions to back up source data stored in one or more primary storage devices associated with a client computing device;
- automatically determine whether replication data stored in one or more replication storage devices is an accurate replication of the source data;
- provide a notification that the replication data is faulty when the replication data is inaccurate;
- when the replication data is inaccurate and a user configuration permits backup from the source data, automatically copy the source data to one or more secondary storage devices to create a secondary copy;
- and
- associate the secondary copy with the source data.
