Abstract: The present disclosure relates to systems, methods, and computer-readable media for determining instances of parity drift in target cloud computing systems as well as determining when instances of parity drift require addressing. For example, in various implementations, a cloud parity drift detection system compiles information about services, configurations, versions, etc. along with additional data from a reference cloud system into a job package and provides the job package to one or more target cloud computing systems. The cloud parity drift detection system can then utilize the job package to compare corresponding information on the reference cloud system to a target data set of the target cloud system to determine instances of parity drift at the target cloud system. Additionally, the cloud parity drift detection system can determine and act when instances of parity drift require addressing.

Abstract: Various embodiments for managing production data are described herein. In one example of a method for managing production data, the method can include allocating, via a processor, a first storage area to store production data for an external computing device. The method can also include receiving a write request comprising production data to be stored in the first storage area. In addition, the method can include detecting that the first storage area does not have available space to store the production data and allocating, via a processor, a second storage area to store the production data. Furthermore, the method can include transferring, via a processor, production data stored in the first storage area to a backup device.

Abstract: Embodiments of the present invention provide a scalable, efficient way to backup data in a block-level incremental-forever backup system such that backup and expiration of data can be achieved at the granularity of a single backup version, without having to read or move data that is stored in backup storage.

Abstract: Provided are a computer program product, method, and system for backing-up a volume of blocks of data in a storage system. Selection is received of selected files in a volume indicating files to backup. A determination is made from the selected files blocks in the files to backup. A volume backup map is generated indicating the determined blocks to backup. A file list of the selected files to backup and the volume backup map are stored in backup information for the backup. The blocks indicated to backup in the volume backup map are copied to a backup file on a block-by-block basis.

Abstract: For block level backup, a full image level backup is created of a file system from production storage at a production server to random access storage at a backup server. A mounted image is created from the full image that exposes a block level representation of the file system of the production server for read operations in a file level format. File enumeration is performed on the mounted image for files. Block level read operations are monitored while the files are being enumerated. During monitoring, blocks that are read for the read operations are marked as meta-data blocks. Blocks that are not marked as meta-data blocks are identified as data blocks. The data blocks are migrated to sequential storage, while leaving the meta-data blocks on the random access storage, wherein the data blocks form a backup image.

Abstract: A transaction structure for issuing a debt instrument. The transaction structure includes a first entity and a second entity. The first entity transfers an asset in exchange for receiving a beneficial interest in the asset, then issues the debt instrument. The debt instrument is backed by a market value of the asset. The second entity issues the beneficial interest in the asset in exchange for receiving the asset. The market value of the asset is determined by a clearing price of a Dutch auction.
