Abstract
The disclosed computer-implemented method for recovering data may include (i) accumulating a list of changed blocks that have changed in a replicated source volume over a continuous-data-protection window of time, (ii) receiving a request to recover data in a replication target volume of the replicated source volume, (iii) converting the changed blocks to a changed-block volume that is paired with the replication target volume, (iv) launching a virtual machine from the replication target volume and the paired changed-block volume, (v) determining that an intercepted read request is directed to a changed block stored within the changed-block volume, and (vi) redirecting the intercepted read request from the replication target volume to the changed-block volume to fulfill the intercepted read request. Various other methods, systems, and computer-readable media are also disclosed.
