Examples of systems and methods for cataloging image-based backups are disclosed. In certain implementations, these systems and methods can obtain information about file system structure from a volume undergoing image-based backup. The systems and methods can generate a catalog of the file system structure that can be stored with the backup image. The systems and methods can generate a searchable index of the catalog so that users can search for files within the backup image without being required to manually mount the backup image containing the searched-for file. As a result, in certain embodiments, users advantageously can more quickly locate and restore files from image-based backups.

Cataloging system for image-based backup

The present invention provides a method for conveying information over a communication network such as a Digital Loop Carrier (DLC) network free of in-band signaling information for at least a portion of an established communication between at least two users so as to reduce the information error rate associated with the established communication. For communication links that support robbed-bit signaling (RBS), the RBS signaling is disabled to allow the communication link to be operated in a clear channel mode. When appropriate, operations can be switch from the clear channel mode back to the RBS mode. Embodiments are described for one-stage DLC systems having a local digital switch (LDS) connected to a remote terminal (RT) by a communication link conforming to either the TR-303 protocol or the TR-008 protocol. In addition, embodiments are described for two-stage DLC systems that also have a distance terminal (DT) connected to the RT by a second communication link.
