TL;DR: In this article, the authors present a system for replicating a client data set on a computer using an application software on the computer, generating a manifest of a target data set during replication containing state of target data reflecting post-update state; determining differences between the local data and manifest to determine required backup operations.

TL;DR: A data recovery system as mentioned in this paper includes a plurality of customer computers to be backed-up, each customer computer running a client software to communicate back-up data files; a system management platform coupled to the client software over the Internet, the system management platforms receiving inputs from a web user portal to control operations of the client Software and the System Management Platform (SMP) to back up the customer computer.

TL;DR: In this paper, the authors describe a system for backing up a computer with a distributed meta data store by splitting meta data from file data, storing the meta data for each file in a separate file, and mapping the file data and meta data to an arbitrary file system.

TL;DR: In this paper, the authors described a system for backing up a client data set on a computer by identifying changed files, generating a first sub-file signature for one or more segments of a changed file, and subsequently generating a second sub file signature for each file segment to detect insertions, removals and rearrangements of data in the file.
