AUTOMATIC CLOUD-BASED DISASTER RECOVERY SYSTEM

摘要

Restoration devices in a cloud storage system are paired with source containers associated with a mainframe computer, and series of commands are generated based on the pairings to cause copies of data at the source containers to be stored to the restoration devices. A point-in-time copy of the copy of the data at the source containers may be stored to some restoration devices, and a second copy of the data may be stored to other restoration devices. The restoration devices may be reallocated from inactive source containers. Execution of the commands is monitored, and the commands are modified if the execution of the commands does not satisfy one or more desired conditions. For example, a cycle time associated with copying data to a restoration device may be measured, and if the cycle time exceeds a threshold, the command may be modified.

主权项

1. A method comprising:
identifying, by a processor, a first restoration device included in a plurality of restoration devices associated with a cloud storage system, wherein the first restoration device is paired with a first source container during a first time period, and wherein data stored by the first source container is copied to the first restoration device during the first time period based on the first restoration device being paired with the first source container; determining, by the processor, that a second source container is storing data to be backed up during a second time period that is subsequent to the first time period; pairing, by the processor, the second source container with the first restoration device during the second time period based on determining that the second source container is storing data to be backed up during the second time period, wherein data stored by the first source container is not copied to the first restoration device during the second time period based on the first restoration device being paired with the second source container; generating, by the processor, a first command based on pairing the second source container with the first restoration device, wherein the first command causes data stored at the second source container, during the second time period, to be copied to the first restoration device; determining, by the processor, a first cycle time for copying the data stored at the second source container to the first restoration device; and modifying, by the processor, the first command when the first cycle time is greater than a threshold value.
