摘要：
A method and apparatus for backing up data in the source LUN is disclosed. The method for backing up the data in a source Logic Unit Number (LUN), includes: copying the data which needs to be modified in the source LUN to a resource pool; monitoring the resource utilization amount in the resource pool; creating a target LUN when the resource utilization amount exceeds a preset threshold; and copying the unmodified data in the source LUN and the backup data of the source LUN in the resource pool into the target LUN.
