Abstract
A distributed data store may provide volume recovery access to multiple recovery agents. A data volume may be maintained for a storage client at the distributed data store. Write access to the data volume may be granted according to a single writer consistency scheme. When a recovery event is detected for the data volume, the data volume may be made available to multiple recovery agents that may perform respective recovery operations. Upon first completion of a recovery operation for the data volume, granting access to the data volume according to the single writer consistency scheme may be resumed. In some embodiments, the distributed data store may be a log-structured data store.
