Abstract

A method and system for migrating data and metadata from a first backup system to a second backup system via a content staging system is disclosed. The system accesses the backup data from the first backup system and restores it, along with the associated metadata, to a staging system. A metadata file is created at the staging system which comprises of the metadata that is to be migrated to the second backup system. The system then migrates the data from the staging system to the second backup system. The metadata is also migrated to the second backup system in a format such that it can be indexed. As a result, the migrated data can be browsed and searched based on one or more search criteria based on the associated metadata. Other details are provided herein.

Claims

1. A computer-implemented method for migrating content from a first content backup system to a second content backup system via a content staging system, the method comprising:

accessing the content staging system using a location of the content staging system;

generating a list of files at the content staging system to migrate to the second content backup system,

wherein files in the list of files are stored in one or more folders of the first content backup system;

for each folder in the content staging system;

receiving a name and location of each file stored in the folder at the content staging system;

receiving a name and an associated value for that name of a set of properties to associate with each file stored in the folder at the content staging system,

wherein at least one property in the set of properties indicates a file folder directory structure for that folder;

generating a metadata file comprising the received name and location of each file stored in the folder at the content staging system, and names and values of the set of properties associated with that file;

associating the generated metadata file with the folder at the content staging system;

for each metadata file in each folder;

inserting contents of each file stored in the folder into the second content backup system based on the name and location of that file included in the metadata file;

inserting a name and associated value of at least one property associated with that file from the metadata file into an index at the second content backup system;

generating, at the second content backup system, an association between the inserted contents and the inserted property in the index; and

causing the file to be deleted from the content staging system.

2. The computer-implemented method of claim 1, further comprising:

receiving criteria for searching contents of the second content backup system;

searching and retrieving contents of the second content backup system based on the criteria; and

displaying, at a user interface, the retrieved contents, wherein the retrieved contents include at least one file migrated from the first content backup system.

3. The computer-implemented method of claim 1, further comprising:

browsing contents of the second content backup system, wherein the contents include at least one file migrated from the first content backup system; and

restoring the at least one file based on an information management policy.

4. The computer-implemented method of claim 1, further comprising:

receiving, at a user interface, an indication from a user to start migration content from the first content backup system to the second content backup, wherein the indication is based on a migration schedule.

5. The computer-implemented method of claim 1, further comprising:

receiving, at a user interface, the location of the content staging system, wherein the location is a NFS network path of the content staging system.

6. The computer-implemented method of claim 1, further comprising:

receiving, at a user interface, the location of the content staging system, wherein the location is an IP address.

7. The computer-implemented method of claim 1, further comprising:

if inserting the contents of the file into the second content backup system fails;

cancelling migration of all content from the first content backup system to the second content backup system.

8. The computer-implemented method of claim 1 wherein the metadata file is generated automatically using a scripting engine, wherein the scripting engine parses contents of each folder in the content staging system to identify folders for migration to the second content backup system.

9. The computer-implemented method of claim 1 wherein the set of properties associated with the file include one of more of the following names:

backup time,

creation date,

last modified time,

version number,

author,

owner,

folder name,

folder identifier,

folder path,

server name,

authorized user identifier,

type of file,

size,

computer,

category,

tag, or

title.

10. A tangible computer-readable storage medium storing instructions, which when executed by at least one data processing device, performs a method for migrating content from a first content backup system to a second content backup system via a content staging system, the method comprising:

accessing the content staging system using a location of the content staging system;

generating a list of files at the content staging system to migrate to the second content backup system,

wherein files in the list of files are stored in one or more folders of the first content backup system;

determining, for each folder in the content staging system, whether a metadata file is present,

wherein each metadata file comprises a name and location of each file stored in the folder at the content staging system and a set of properties associated that file,

wherein each property in the set of properties comprise a name and an associated value for that name, and

wherein at least one property in the set of properties indicates a file folder directory structure for that folder;

for each metadata file in a folder;

inserting contents of each file stored in the folder into the second content backup system based on the name and location of that file included in the metadata file;

inserting a name and associated value of at least one property associated with that file from the metadata file into an index at the second content backup system;

generating, at the second content backup system, an association between the inserted contents and the inserted property in the index; and

causing the file to be deleted from the content staging system.
