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:
receiving metadata information associated with data stored within a distributed file system having a namespace, 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 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; and creating an image of the secondary namespace when a request to create an image of the distributed file system is received, the image of the secondary namespace created using an image creation feature of the local file system.
