DISTRIBUTED FILE SYSTEM SNAPSHOT

摘要

Technology is disclosed for managing data in a distributed file system (“the technology”). The technology can gather metadata information associated with the data stored within the distributed file system, create a secondary namespace within a local file system of a local host using the gathered metadata information and store the gathered metadata information as files within the secondary namespace. Further, when a request to create a PPI of the distributed file system is received, the technology can create a PPI of the secondary namespace using a PPI creation feature of the local file system.

主权项

1. A computer implemented method, comprising:
gathering metadata information associated with data stored within a distributed file system, the metadata information being stored within a namespace of the distributed file system, the namespace maintaining a hierarchy of files and directories associated with the stored data; creating a secondary namespace within a local file system using the gathered metadata information, a hierarchy of files and directories in the secondary namespace corresponding to the hierarchy of files and directories in the namespace of the distributed file system, the gathered metadata information being stored within the secondary namespace; and creating a point-in-time image (PPI) of the secondary namespace when a request to create a PPI of the distributed file system is received, the PPI of the secondary namespace created using a PPI creation feature of the local file system.
