A method for information management comprises intercepting an output from an application; distributing packets according to a routing scheme, wherein the packets are associated with the output, and wherein distributing the packets may occur when the application is associated with a first operating system, and may also occur when the application is associated with a second operating system; and storing the packets.

Versatile information management

Information management is disclosed. A file output from an application to an operating system is intercepted before the file output arrives at the operating system. The file output is directed towards protected data. The intercepted file output is analyzed to determine whether a predetermined type of version of the protected data has been created. In the event it is determined that the predetermined type of version of the protected data has been created at least in part because the analyzed intercepted file output includes a modification to the protected data, the protected data automatically backed up, including by storing at least a portion of the file output as a backup version of the protected data. In the event it is determined that the predetermined type of version of the protected data has not been created, the protected data is not backed up.

Backup information management

A method for information management comprises monitoring output from an application to an operating system, wherein the output is monitored substantially continuously; determining if a policy applies to data associated with the output; and executing the policy if the policy applies.

Information management

In one embodiment, a method for information management comprises monitoring output from an application, wherein the output is monitored substantially continuously; determining if the output is associated with a predetermined type of version; and saving data associated with the output if the output is associated with the predetermined type of version.

An indication to allocate storage is received, where the storage is to be used to store previous version data associated with a protected data set. One or more storage groups are allocated of at least a prescribed allocation group size and comprising a set of physically contiguous storage locations.

Linear space allocation mechanisms in data space

In an embodiment of the invention, a technique for indexing data is disclosed. The technique comprises receiving packets; counting the received packets; determining whether there is a pattern associated with the received packets; and using a first algorithm if it is determined that there is a pattern.

Index processing

Previous version data is copied to a location in a collection of snapshot data, wherein the collection of snapshot data represents a state of a protected data set at a baseline time associated with a snapshot. Once the previous version data has been copied to the location in the collection of snapshot data, an index is updated to associate the location in the collection of snapshot data with the previous version data. A data region storage location from which the previous version data was copied to the location in the collection of snapshot data is making available for reuse once the index has been updated.

Updating snapshots

In some embodiments, a technique for processing a character comprises receiving a character; determining whether the character is in a predetermined language; transforming the character to a symbol associated with a private area of Unicode if it is determined that the character is not in the predetermined language; and storing a result of the transformation.
