Abstract
Example implementations relate to data backup. For example, a data backup can include tracking a location of a data block on a first node and initiating a transfer, utilizing a backup power supply, of the data block to a non-volatile memory location on a second node in response to an interruption of a primary power supply. In addition, the data block can be restored to the tracked location of the first node responsive to a restoration of the primary power supply.
Claims15
A data backup system, comprising:
- a track engine to track a location of a data block on a first node;
- an initiate engine to initiate a transfer, utilizing a backup power supply, of the data block to a non-volatile memory location on a second node in response to an interruption of a primary power supply;
- and
- a restore engine to restore the data block to the tracked location of the first node responsive to a restoration of the primary power supply.
A non-transitory machine readable medium storing instructions executable by a processing resource to cause a computing device to:
- track a location of a data block on a first node;
- initiate a transfer, utilizing a backup power supply, of the data block from the first node to a non-volatile memory location on a second node in response to an interruption of a primary power supply;
- mange a shutdown of the first node after the transfer;
- and
- restore the data block to the tracked location of the first node from a pool of non-volatile memory location on the second node.
A method for data backup, comprising:
- monitoring a plurality of nodes and a corresponding backup power supply;
- initiating a transfer, utilizing the backup power supply, of data from at least a first node of the plurality of nodes to a non-volatile memory location on a second node of the plurality of nodes in response to an interruption of a primary power supply of the plurality of nodes;
- shutting down each node of the plurality of nodes upon completing the transfer of its respective data;
- restoring the data to its originating node of the plurality of nodes upon restoration of the corresponding backup power supply.
