PRIORITIZING BACKUPS ON A DISK LEVEL WITHIN ENTERPRISE STORAGE

摘要

A system, method, and computer program product provide a process that includes storing data on first data storage devices, and a backup copy of the data on the first and/or on second ones of the data storage devices. A probability of a failure of each of at least some of the first and/or second data storage devices is determined, and at least one of the first and/or data storage devices that is determined to have a higher probability of failure than a threshold and/or a probability of failure of another of the data storage devices, is selected. A second backup copy of the data, stored on the selected data storage device(s), is also stored on third ones of the data storage devices. The first and/or second data storage devices determined to have the higher probability of failure are used for their designated purpose after the second backup copy is created.

1. A system, comprising:
a manager configured to communicate with a plurality of data storage devices, the manager including:
hardware for communicating with the plurality of data storage devices;logic configured to cause data to be stored on first ones of the data storage devices;logic configured to cause storage of a backup copy of the data on the first and/or on second ones of the data storage devices;logic configured to determine a probability of a failure of each of at least some of the first and/or second data storage devices;logic configured to select at least one of the first and/or second data storage devices determined to have a higher probability of failure than at least one of: A) a threshold, and B) a probability of failure of another of the data storage devices;logic configured to cause a second backup copy of the data stored on the selected at least one of the first and/or second data storage devices to be stored on third ones of the data storage devices; andlogic configured to use the at least one of the first and/or second data storage devices determined to have the higher probability of failure for a designated purpose thereof after the second backup copy of the data is created.
