4. The system as recited in claim 1 , wherein the backup version of the additional storage object is generated during a generation of a backup version of the source data set.
5. The system as recited in claim 1 , wherein the backup manager is configured to create the additional storage object in response to a detection of a triggering condition.
6. The system as recited in claim 5 , wherein the information comprises configuration information associated with the primary host, wherein the triggering condition is a change to the configuration information associated with the primary host, and wherein the backup manager is further configured to:
monitor one or more sources of the configuration information associated with the primary host for changes to the configuration information.
7. The system as recited in claim 1 , wherein the information includes system state information, wherein at least a portion of the system state information is used during a host initialization process.
8. The system as recited in claim 1 , wherein the information includes information indicative of a sharing of a storage device across multiple hosts.
9. The system as recited in claim 1 , wherein the backup version of the additional storage object is maintained at a secondary host, wherein the backup manager is further configured to:
extract at least a portion of the information from the backup version of the additional storage object at the secondary host; and
emulate a configuration setting of the primary host at the secondary host using the at least a portion of the information.
10. The system as recited in claim 1 , wherein the backup manager is further configured to:
store the additional storage object at a location reserved for containers of information encapsulated for backup within the source data set.
11. The system as recited in claim 1 , wherein the information comprises configuration information, wherein the backup manager is further configured to:
in response to a restoration request,
regenerate configuration information from the backup version of the additional storage object; and
set up a configuration of a restoration target in accordance with the configuration information regenerated from the backup version.
12. A computer readable medium comprising program instructions, wherein the instructions are computer-executable to implement a backup manager configured to:
generate one or more backup versions of a plurality of storage objects of a source data set of a primary host;
create an additional storage object, wherein the additional storage object includes information collected from a designated information source in a first format, the first format being a format unsuitable for backup by the backup manager;
generate a name for the additional storage object, wherein the name includes a pattern identifying the additional storage object as a container of information in a format unsuitable for backup by the backup manager encapsulated for backup;
store the additional storage object in the source data set in a second format, the second format being a format suitable for backup by the backup manager; and
generate a backup version of the additional storage object.
13. The computer readable medium as recited in claim 12 , wherein the backup manager comprises a replication engine configured to replicate storage objects that are stored in a particular storage format, and wherein the second format is the particular storage format.
