Migrating data to disk without interrupting running backup operations
First Claim
1. A method, performed by a media agent of an information management system, for refreshing mount paths of a magnetic disk data storage library, the method comprising:
- accessing a request to replace an existing magnetic disk storing one or more data volumes and associated with one or more mount paths associated with a new magnetic disk,wherein the request is accessed while secondary copy operations associated with the one or more mount paths are currently running,wherein the secondary copy operations include transferring data to one or more partitions of the existing magnetic disk, andwherein the one or more partitions are mapped to the one or more mount paths of the magnetic disk data storage library;
for all non-active mount paths, migrating, at a first time, data volumes associated with the non-active mount paths to the new magnetic disk;
for all active mount paths associated with currently running secondary copy operations;
marking each mount path as non-active when a running secondary copy operation associated with the mount path has completed a job; and
migrating, at a second time later than the first time, data volumes associated with the mount path marked as non-active to the new magnetic disk; and
for all mount paths migrated to the new magnetic disk, marking each mount path as resident on the new magnetic disk.

Abstract
Systems and methods for migrating stored backup data between magnetic disks (e.g., from an existing magnetic disk to another disk), such as a new or different magnetic disk in a magnetic storage library, without interrupting or otherwise affecting secondary copy operations (e.g., operations currently writing data to the storage library) utilizing the magnetic storage library, are described. In some embodiments, the systems and methods mark one or more mount paths as full when a running secondary copy operation associated with the mount path has completed a job (regardless of the actual current capacity or intended use of the mount path), and migrate each of the one or more data volumes to a second magnetic disk of the magnetic library when the mount path associated with the data volume is marked as full.

11. A system, comprising:
-
at least one processor; at least one data storage device coupled to the at least one processor and storing instructions for implementing a process to migrate data volumes between magnetic disks, wherein the process comprises; accessing, via an access component, a request to migrate data volumes stored on an existing magnetic disk to a new disk, wherein the request is accessed while secondary copy operations are currently running to transfer data to the existing magnetic disk; and for all active mount paths associated with the currently running secondary copy operations transferring data to the existing magnetic disk, marking, via a migration component, each mount path as full when a running secondary copy operation associated with the mount path has completed a job to transfer data to the existing magnetic disk, and migrating, via the migration component, data volumes associated with the mount path marked as full to the new disk. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A computer-readable medium, excluding transitory propagating signals, storing instructions that, when executed by an information management system, cause the information management system to perform a secondary copy operation of data to magnetic disks of a magnetic library, the method comprising:
-
transferring data to one or more data volumes contained in one or more partitions of a first magnetic disk of the magnetic library, wherein the one or more partitions are associated with one or more mount paths through which data is transferred to the one or more data volumes stored by the one or more partitions of the first magnetic disk; marking each of the one or more mount paths as full when a running secondary copy operation associated with the mount path has completed a job; and transferring each of the one or more data volumes to another data storage medium when the mount path associated with the data volume is marked as full. - View Dependent Claims (20)
