Abstract: A system receives a stream of fingerprints, which correspond to segments of a data file, from a source of the data file, and identifies fingerprints in the stream of fingerprints as fingerprints formatted by a first fingerprint format or a second fingerprint format. If a fingerprint, in the stream of fingerprints, does not duplicate any fingerprint in a fingerprint cache, the system stores the non-duplicate fingerprint in a first storage tier corresponding to the first fingerprint format or a second storage tier corresponding to the second fingerprint format. The system requests a segment of the data file, which corresponds to the non-duplicate fingerprint, from the source of the data file. The system receives the requested segment of the data file from the source of the data file, and stores the received segment of the data file in destination storage.

Abstract: During a current backup of a file system of a client, a determination is that a file in the current backup includes first data regions found in a file from a previous backup, and second data regions that are new. A virtual synthetic file is generated by writing the second data regions, and synthesizing the first data regions by referencing the file from the previous backup. A request received to restore the particular file includes identifications of other files still present at client. A determination is that the particular file corresponds to the virtual synthetic file and that the other files still present at client include the file from the previous backup. The second data regions are read to send to client. A complete version of the particular file is assembled at client using the file from the previous backup, still present at client, and the second data regions.

Abstract: Embodiments described herein are directed to backing up and recovering cloud-native applications. In some embodiments, the data engine maps a first set of data volumes to a data repository dedicated to store a backup of the data associated with the application. Furthermore, the data engine transmits, using a dynamically generated process, the data stored in the identified first set of data volumes to the data repository for backup based on the mapping. The data engine may also initiate a recovery of the application. The data engine may use a new dynamically generated process to identify and transmit a respective data set to a corresponding data volume for storage. Moreover, the data engine may use the new process to restore the components of the application using each respective identified data set.

Abstract: Mechanisms are provided for processing a sequential database natural language query. A process model is preprocessed to generate mapping data structure(s). The mapping data structure(s) map elements of the sequential process to other elements of the sequential process to thereby identify sequential and dependent characteristics of the sequential process. A sequential database natural language (SDNL) query interpretation engine is configured with the mapping data structure(s) and natural language processing is performed on a query to generate extracted features. The configured SDNL query interpretation engine operates on the extracted features and the mapping data structure(s) to generate intent information for the query. Executable database queries are generated based on the intent and executed on a database to return a response to the query.
