DATA RECOVERY USING BITMAP DATA STRUCTURE |
| 摘要 |
Examples of the present disclosure describe implementing bitmap-based data replication when a primary form of data replication between a source device and a target device cannot be used. According to one example, a temporal identifier may be received from the target device. If the source device determines that the primary replication method is unable to be used to replicate data associated with the temporal identifier, a secondary replication method may be initiated. The secondary replication method may utilize a recovery bitmap identifying data blocks that have changed on the source device since a previous event. |

1. A method comprising:
receiving a temporal identifier from a target device; determining that a primary replication method is unable to be used to replicate data associated with the temporal identifier; and initiating replication of data using a secondary replication method, wherein the secondary replication method utilizes a recovery bitmap identifying data blocks that have changed on a source device since a previous event. |
