Abstract

Defined backup using a computerized tool is enabled. For example, a system can comprise a processor that executes computer executable components stored in a computer-readable memory. The computer executable components can include a fragment component that segments data that has not changed since a previous backup of a data storage device into a defined quantity of a plurality of fragments and a backup component that performs one or more defined backups on the data storage device. In various embodiments, the one or more defined backups can comprise one of the plurality of fragments of the data that has not changed since the previous backup of the data storage device and incremental data. The incremental data may include data that has changed since the previous backup of the data storage device.

Claims16

Dependent claims

A system comprising:

a processor that executes computer executable components stored in a computer-readable memory, wherein the computer executable components comprise:
a fragment component that segments data that has not changed since a previous backup of a data storage device into a defined quantity of a plurality of fragments;
and
a backup component that performs one or more defined backups on the data storage device, the one or more defined backups comprising:
one of the plurality of fragments of the data that has not changed since the previous backup of the data storage device;
and
incremental data, wherein the incremental data comprises data that has changed since the previous backup of the data storage device, wherein elements of the one or more defined backups comprise identifiers associated with respective data of the data storage device;
and
a data overwrite component that updates contents of corresponding data without changing elements of a corresponding set of one or more defined backups in response to a determination that data represented by an identifier of the identifiers is overwritten.

6 more elements

A non-transitory machine-readable medium comprising executable instructions that, when executed by at least one processor, facilitate performance of operations comprising:

segmenting data that has not changed since a previous backup of a data storage device into a defined quantity of a plurality of fragments;
and
performing one or more defined backups on the data storage device, the one or more defined backups comprising:
one of the plurality of fragments of the data that has not changed since the previous backup of the data storage device;
and
incremental data, wherein the incremental data comprises data that has changed since the previous backup of the data storage device, wherein elements of the one or more defined backups comprise identifiers associated with respective data of the data storage device;
and
updating contents of corresponding data without changing elements of a corresponding set of one or more defined backups in response to a determination that data represented by an identifier of the identifiers is overwritten.
