For the cloud storage file system, the complex retrieval and recycling process leads to the system's ability to process user data, based on the log structure Distributed File System (hdfs-based log-structured file System,hlfs), This paper proposes a method to improve the effective utilization of cloud storage space by means of efficient recovery management of system resources, and finds the use of hlfs in the middle part through bitmap marking, and realizes the management and recovery of HLFS resources. The experimental results show that the bitmap tag can improve the efficiency of garbage collection after the application of resource management in cloud storage system.
