Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. In the case of a failed volume, a new volume can be created and populated with data from the surviving volume. During population, new writes can continue to be replicated to the new volume. The population process can write data from the surviving volume to the new volume “under” new writes, such that the population process does not overwrite data included in the new writes.

Abstract: Generally described, one or more aspects of the present application correspond to a highly distributed replica of a volume stored in a networked computing environment. First and second replicas of the volume can be synchronously replicated, and some implementations of the tertiary replica can be asynchronously replicated. The highly distributed nature of the tertiary replica supports parallel data transfer of the data of the volume, resulting in faster creation of backups and new copies of the volume.

The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Each volume can be implemented by at least two computing devices, a first of which is configured as a primary device to which reads from and writes to the volume are directed. Of the two volumes, one can be indicated as primary, indicating authority to accept reads to and writes from the virtualized device. A primary device of the primary volume, on obtaining a write to the volume, can replicate the write to both a secondary device of a primary volume and to the secondary volume.

Abstract: A snapshot object or other type of object may be stored in a first storage system and may be accelerated in another storage system, wherein an accelerated snapshot or other type of object can be used to populate volumes in the other storage system with data more rapidly than a non-accelerated snapshot or other type of object. The accelerated snapshot or other object may be implemented using an intermediate volume implemented in the other storage system that is populated with data from the snapshot object or the other object stored in the first storage system.

The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Each volume can be implemented by at least two computing devices, a first of which is configured as a primary device to which reads from and writes to the volume are directed. To ensure consistency in the distributed device, a multi-tier authority service is implemented, in which a cross-computing system authority service designates a volume as having authority to accept writes to the virtualized device, and in which a second tier authority service designates a computing device as having authority to accept writes to the volume.

Abstract: Generally described, one or more aspects of the present application correspond to a highly distributed replica of a volume stored in a networked elastic computing environment. First and second replicas of the volume can be synchronously replicated, and some implementations of the tertiary replica can be asynchronously replicated. The highly distributed nature of the tertiary replica supports parallel data transfer of the data of the volume, resulting in faster creation of backups and new copies of the volume.

Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Due to separation between volumes, replication lag may occur, in which data persisted to a first volume is not immediately persisted to a second volume. Such lag can increase a potential for data loss in the event that the first volume fails. Embodiments of the present disclosure relate to managing data loss risk by determining an expected maximum difference between the data stored at the two volumes, in a manner that does not require decrypting the data written to the volumes or perfect knowledge of the state of the distributed system at a single point.

Abstract: The present disclosure generally relates to creating virtualized block storage devices whose data is replicated across isolated computing systems to lower risk of data loss even in wide-scale events, such as natural disasters. The virtualized device can include at least two volumes, each of which is implemented in a distinct computing system. Each volume can be encrypted with a distinct key, and an encryption service can operate to transform data “in-flight” on the replication path between the volumes, reencrypting data according to the key appropriate for each volume.
