One example method includes performing data protection operations including backup operations. Backups of an availability group include a full backup, transaction log backups, and differential backups. Each differential backup includes transactions since the full backup. The differential backups are performed based on a trigger and, during a restore operation, the differential backups reduce the number of restores that need to be performed and can be restored instead of restoring the corresponding transactional log backups.

Systems and methods for utilizing tablespace to export from a foreign database recovery environment are described. The system includes a backup host that operates in a foreign database recovery environment and receives a database from a source host operating in a native database recovery environment. The backup host receives export information including a tablespace identifier and a point-in-time. The tablespace includes file information for export from the backup host to the source host. A job is initiated on the backup host to generate script information (including logic for execution on the source host to recover the tablespace, at the point-in-time, in the database on the source host), create directories on the backup host, materialize file information including snapshots of the database and incremental changes to the database, and communicate the file information and the script information, via the directories, to the source host.

The instant invention is related to a telemetry system with devices designed for the specific purpose of auditing transactions within a network. The network infrastructure is specifically configured to provide power to all the connected devices from a single power source. The electronic memory within each module of the system is able to store data locally to prevent data loss if the network is not available for data transfer. Furthermore, a gateway is provided to allow communication to a central database or to store data if a remote network is not available. The system may include a web portal hosted by a dedicated server designed for providing stability and a specific user interface showing only the relevant acquired data to specific users.

Methods and system are provided for determining a system capacity. The system capacity may be determined by performing one or more capacity tests. The one or more capacity tests may produce capacity test results.

A machine station file processing method includes: monitoring operation of a file system of a machine station server and acquiring a transaction file generated by the operation, the transaction file comprising transaction data; converting a format of the transaction data according to preset warehousing rules to generate model-layer data; and sending, to a data warehouse server, the model-layer data and a data analysis request, the data analysis request is used to instruct the data warehouse server to acquire application-layer data according to the model-layer data.

Transaction processing at non-relational databases is disclosed, including: receiving, at a non-relational database, a transaction request to perform a transaction branch from a client, wherein the transaction branch is related to a distributed transaction; sending the global transaction ID to a transaction coordinator to indicate that the transaction branch to be performed at the non-relational database is associated with the distributed transaction; receiving, at the non-relational database, a branch ID corresponding to the transaction branch from the transaction coordinator; determining one or more transaction operations to be performed at the non-relational database from the operation content associated with the transaction branch; executing the one or more transaction operations at the non-relational database; and sending a branch status message indicating execution success or failure of the transaction branch to the transaction coordinator.

In one embodiment, a system for managing a virtualization environment includes a plurality of host machines, wherein each of the host machines comprises a hypervisor and one or more user virtual machines (user VMs), and a virtual machine controller, one or more virtual disks comprising a plurality of storage devices, a virtualized file server (VFS) comprising a plurality of file server virtual machines (FSVMs), wherein each of the FSVMs is running on one of the host machines. The VFS may be configured to receive a request for storage system information from a user and generate and send a response to the request, wherein the response is customized according to configuration information of the VFS that is specific to the user. The storage system information requested may include a total size of storage available to the user, and the user may have an associated storage quota limit.

Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions according to review and approval workflows. The transaction exchange platform may receive transactions from origination sources, which may be added to the SDP as transaction objects. As the transactions are received, the transactions may be analyzed to detect duplicate transactions and/or errors in the transactions. The transaction exchange platform may take steps to remediate transactions that are recognized as duplicates or predicted to generate one or more errors. Similarly, the transaction exchange platform may take steps to remediate transactions that are rejected by a clearinghouse.

An approach is provided for controlling a rate at which requests from a client computer will be received by a server application executed on a server computer. Requests are received by the server computer at different times from the client computer and time intervals between different pairs of successive requests are measured. Based on the time intervals, (1) a historical rate of requests from the client computer is determined and a limit on a rate for the server application to receive subsequent requests from the client computer is determined and enforced based on the historical rate of requests, or (2) a range of the time intervals is determined to be within a predefined range of time intervals and based on the range being within the predefined range, a denial of service attack or an overload of requests from the client computer is determined and blocked.

A probabilistic set sketching data structure for the estimation of properties of individual sets, like cardinality, as well as joint parameters describing relations between different sets, like similarity scores or intersection cardinalities. The memory size of the proposed sketch is widely independent of the size of the observed sets and may be chosen primarily based on the desired estimation error. A tuning parameter controls the amount of information stored in the sketch regarding the content of the monitored set and may be used to trade joint parameter estimation accuracy for sketch size. Improved estimation algorithms are proposed for both cardinality and joint quantities. Especially the proposed joint quantity estimation has considerable advantages, as it reduces the problem of estimating three dependent parameters, like the cardinalities of intersections and the two complements to the estimation of only one parameter, like the Jaccard coefficient.
