Abstract
Storing computer data is provided. Responsive to determining that a first data includes user data, storing the user data to a first storage system, wherein the first storage system provides a first quality of service. Responsive to determining that a second data includes redundant data, storing the redundant data to a second storage system, wherein the second storage system provides a second quality of service that is lower than the first quality of service provided by the first storage system.
Claims20
A method for storing computer data, the method comprising:
- responsive to determining, by one or more processors, that a first data includes user data, storing, by one or more processors, the user data to a first storage system, wherein the first storage system provides a first quality of service;
- and
- responsive to determining, by one or more processors, that a second data includes redundant data, storing, by one or more processors, the redundant data to a second storage system, wherein the second storage system provides a second quality of service that is lower than the first quality of service provided by the first storage system.
A computer program product for storing computer data, the computer program product comprising:
- a computer readable storage medium and program instructions stored on the computer readable storage medium, the program instructions comprising:
- program instructions to determine if data includes user data;
- program instruction to store the user data to a first storage system, wherein the first storage system provides a first quality of service;
- program instructions to determine if data includes redundant data;
- and
- program instructions to store the redundant data to a second storage system, wherein the second storage system provides a second quality of service that is lower than the first quality of service provided by the first storage system.
A computer system for storing computer data, the computer system comprising:
- one or more computer processors;
- one or more computer readable storage media;
- program instruction stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
- program instructions to determine if data includes user data;
- program instruction to store the user data to a first storage system, wherein the first storage system provides a first quality of service;
- program instructions to determine if data includes redundant data;
- and
- program instructions to store the redundant data to a second storage system, wherein the second storage system provides a second quality of service that is lower than the first quality of service provided by the first storage system.
