Utilization of disk buffer for background replication processes |
| 摘要 |
A method for replicating data from a first volume to a second volume includes receiving a first data request comprising a request for a first portion of data, wherein the first portion is part of a first volume. The first portion of data is read, and so is at least a second portion of data in addition to the first portion of data requested in the first data request. In response to determining that the second portion of data should be replicated to the second volume, the second portion of data is written to the second volume. |
