SECONDARY STORAGE PRUNING

摘要

Systems and methods for storage pruning can enable users to delete, edit, or copy backed up data that matches a pattern. Storage pruning can enable fine-grain deletion or copying of these files from backups stored in secondary storage devices. Systems and methods can also enable editing of metadata associated with backups so that when the backups are restored or browsed, the logical edits to the metadata can then be performed physically on the data to create a custom restore or a custom view. A user may perform operations such as renaming, deleting, modifying flags, and modifying retention policies on backed up items. Although the underlying data in the backup may not change, the view of the backup data when the user browses the backup data can appear to include the user's changes. A restore of the data can cause those changes to be performed on the backup data.

1. A method of pruning backup storage data, the method comprising:
under control of a hardware processor comprising digital logic circuitry,
performing a backup of a primary data store, said performing comprising storing backup data in a non-human readable format on a secondary storage device and creating an index of the backup data, the index comprising metadata associated with the backup data;electronically generating instructions for outputting a graphical user interface for presentation to a user, the graphical user interface comprising functionality configured to enable the user to specify a user-defined textual pattern and to request that any files containing the user-defined textual pattern in the backup data be deleted;searching the index for selected files containing the user-defined textual pattern;deleting the selected files containing the user-defined textual pattern from the backup data, said deleting comprising:
logically deleting the selected files containing the user-defined textual pattern without physically removing the selected files from the backup data;subsequent to the logical deletion of the selected files containing the user-defined textual pattern, determining whether a physical deletion policy has been met; andin response to determining that the physical deletion policy has been met, physically deleting the files containing the user-defined textual pattern.
