  • Patent number: 11010089
    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.

  • Patent number: 10922331
    Abstract: Embodiments create a clone of a PDB while the PDB accepts write operations. While the PDB remains in read-write mode, the DBMS copies the data of the PDB and sends the data to a destination location. The DBMS performs data recovery on the PDB clone based on redo entries that record changes made to the source PDB while the DBMS copied the source PDB files. This data recovery makes all changes, to the PDB clone, that occurred to the source PDB during the copy operation. The redo information, on which the data recovery is based, is foreign to the PDB clone since the redo entries were recorded for a different PDB. In order to apply foreign redo information to perform recovery on the PDB clone, a DBMS managing the PDB clone maintains mapping information that maps PDB source reference information to corresponding information for the PDB clone.

  • Patent number: 10915549
    Abstract: Embodiments incrementally refresh a clone of a source PDB while the source PDB accepts write operations. Specifically, refreshing the PDB clone incorporates changes made to the source PDB since a refresh reference time stamp, which marks the time at which the PDB clone was created or, if the PDB clone has been previously refreshed, the time at which the PDB clone was last refreshed. A PDB clone is incrementally refreshed by incorporating, into the PDB clone data, those source data blocks that have changed since the refresh reference time stamp. Recovery is performed on the PDB clone, once the blocks are copied, to apply any changes made to the source PDB while the blocks were being copied, which recovery makes the PDB clone files consistent. This recovery is based on redo entries recorded for the source PDB during the time it took to copy the blocks to the PDB clone.

  • Patent number: 10902018
    Abstract: Embodiments described herein are directed to enabling a user to modify data stored locally during a data migration process in which the user's data is being transferred to the cloud. For instance, a synchronization service requests the user's device (e.g., a client-based server) to provide a hash value for each data object maintained thereby (including modified data objects) and compares the hash values to hash values generated for the data uploaded to the cloud. If a hash value provided by the server does not match any of the hash values generated for the uploaded data, this means that the data object associated with the unmatched hash value has been modified since the initiation of the data transfer process. The synchronization service receives the modified data object from the server and uploads it to the cloud, thereby synchronizing the data uploaded to the cloud with the data locally-maintained by the server.

  • Patent number: 10896200
    Abstract: A distributed data storage system includes first and second data storage systems (DSSs) at respective sites and a cloud gateway at a third. The first DSS remotely mirrors data using synchronous and asynchronous channels both employing a block-based protocol (e.g., SCSI). The second DSS is connected to the synchronous channel to provide synchronous backup to the first DSS. The cloud gateway is connected to the asynchronous channel and has a cloud storage connection to a cloud storage system, the cloud storage connection using a wide area network interface and employing an object-based protocol. The cloud gateway (1) provides asynchronous backup to the first DSS via the asynchronous channel, and (2) uses the cloud storage connection to access object-based cloud data storage to store data of the asynchronous backup. The use of the cloud gateway and cloud storage system for an asynchronous third mirror enhances reliability/resiliency in a cost-effective manner.
