Abstract: In accordance with various embodiments, described herein are systems and methods for enabling backup and recovery of cloud services (services) in a cloud computing environment (cloud environment). The techniques described herein can be used, for example, to facilitate restoration of a service that may have been originally provisioned as part of a user system/environment, within the cloud environment, and was subsequently lost due to accident deletion of the service, or cloud account termination. A service archive, created during a backup process, includes an archive file that contains the artifacts that were installed and/or created when the service was provisioned; and a metadata file that contains the current state information for the service when the backup was performed. During a recovery process, a lost service can be provisioned within the user system/environment, using the contents of the service archive, irrespective of whether the service itself still exists within the user system/environment.

Abstract: Methods, systems, and devices supporting a data model for emissions analysis are described. Some database systems may store emissions data and support a sustainability application. The sustainability application may display reports that track and analyze data related to carbon emissions. In some cases, underlying data for a report is missing from the database system. The system may support extrapolation techniques to estimate the missing data and aggregate the underlying data—including the extrapolated values—according to a data schema of the database to calculate fields in a report. In some cases, a single data record may be used to generate multiple reports. The system may send one or more results to a user device for display in a user interface (e.g., in one or more dashboards). Additionally or alternatively, the system can display underlying calculations (e.g., report calculations, extrapolation calculations, etc.) in the user interface to support auditing activities.

Abstract: A computing environment includes a home site and a cache site with nonhomogeneous thin-provisioned storage configurations. A file management system updates files stored at the cache site. Each updated file has an updated file size and a pre-update file size. When a resynchronization is needed between the cache site and the home site, for example due to an extended communication failure, the storage requirement changes for the updated files are calculated and a notification is sent to the home site. The notification identifies the updated files and the storage requirement changes. The home site sends a reply to the cache site. The reply identifies which files are approved for immediate processing. The cache site transfers resynchronization data for the approved files to the home site, and delays transferring resynchronization data for the unapproved files until subsequent replies from the home site indicate that the previously unapproved files are now approved.

Abstract: Implementations relate to sharing user activity data with other users. In some implementations, a method includes evaluating one or more actions of a second user to detect that the second user is interested in one or more attributes of one or more activities performed by a first user and described in activity data of the first user. A request is provided to the first user to share at least a portion of the activity data with the second user. The method receives, in response to the request, an indication from the first user to share a designated portion of the activity data with the second user. The method causes the activity data to be made accessible to the second user, and provides information for presentation via a device to the second user, where the presented information is derived from the shared portion of the activity data.
