TLDR
In this article, the file system metadata associated with file system objects that have been created and/or modified since the last backup is used to generate metadata files for the incremental backup.Abstract:
Metadata generate for incremental backup is disclosed. A subset of blocks used to store file system metadata are identified in a set of blocks changed since a last backup. File system metadata stored in the subset of blocks is used to obtain file system metadata associated with file system objects that have been created and/or modified since the last backup. The file system metadata associated with file system objects that have been created and/or modified since the last backup is used to generate file system metadata files for the incremental backup.read more

Incremental copy performance between data stores
TL;DR: In this article, the authors describe a hybrid storage pool for copying a data object to a target storage pool using a hybrid of storage pools, in which at least one of the storage pools is particularly efficient at identifying data that should be used for copying the data objects to the target storage, and at least another storage pool is especially efficient at retrieving the data.
Patent
Successive data fingerprinting for copy accuracy assurance
TL;DR: In this paper, the authors present a system for checking the integrity of a data object copied between storage pools by comparing data fingerprints of data objects, comprising scheduling a series of successive copy operations over time for copying data objects from a source data store to a target data store.
Patent
Computerized methods and apparatus for incremental database backup using change tracking
TL;DR: In this paper, the authors describe methods and systems for creating an incremental backup of application data by creating a snapshot associated with a current incremental backup, using a change tracking bitmap.

Hierarchical wide spreading of distributed storage
David Slik,Barry Patrick Benight +1 more
TL;DR: In this article, a front-end node associates a respective subset of the redundancy data with each of the multiple source data segments, wherein each subset of redundancy data and associated source data segment form an encoded segment.
Patent
Resiliency fragment tiering
TL;DR: In this paper, a data storage architecture can be implemented in a single-tier configuration and/or a multi-tier configurable configuration, where the I/O operations for rebuilding the data in case of device failures is spread across many storage devices.

Method and system for backing up digital data
TL;DR: An improved backup system for computer networks provides simplified operation, reduced utilization of computer system resources, and increased recovery potential in the events of information loss as discussed by the authors, where the file stream flowing from the computer system to the backup system contains metadata at the boundaries of each file.
Patent
System and method for providing automated electronic information backup, storage and recovery
TL;DR: An automated electronic information backup, storage migration, and recovery system as mentioned in this paper includes techniques for automatically observing all file events over a plurality of computing devices, and a relevancy of those file events are determined based on application information repository.

Incremental file system differencing
Timothy Bisson,Shankar Pasupathy +1 more
TL;DR: In this article, the authors propose a comparison unit and a catalog unit for comparing two datasets and identifying metadata differences between the two datasets irrespective of the manner in which the data is stored.
Patent
Profiling backup activity
TL;DR: In this article, a network security threat is disclosed and a set of remedial actions are performed if it is determined that a potential threat has been indicated and the received information is stored.

Incremental dump with a metadata container walk using inode-to-parent mapping information
TL;DR: In this paper, a traversal engine that traverses through metadata containers (e.g., inodes) in a file system and determines the metadata containers that have been modified (added, changed, deleted, or renamed) within a particular time interval is presented.
