Abstract: Certain embodiments described herein are generally directed to selecting a target storage profile for comparison to a recovered storage profile in support of a data recovery operation. In some embodiments, a method includes comparing a first plurality of fields of the reference storage profile with a second plurality of fields of a first target storage profile of the one or more target storage profiles to determine a degree to which the first target storage profile matches the reference storage profile, the first plurality of fields comprising a first plurality of storage requirements, and the second plurality of fields comprising a second plurality of storage requirements.

Abstract: Techniques disclosed herein relate to synchronizing a first database with a second database. Embodiments include detecting a write operation modifying properties of a data object in the first database. While the data object is locked, embodiments write object change data to a journal table. Embodiments query the journal table of the recovery database to retrieve a portion of the object change data corresponding to a first window of time and comprising a plurality of entries. The retrieved portion of object change data is processed to create processed object data by collapsing duplicate entries within the plurality of entries. Embodiments retrieve object data from the first database, corresponding to properties of data objects specified in the processed object change data. The retrieved object data is pushed to the second database, whereby the second database is synchronized with the first database.

Abstract: Embodiments perform token cache management by renewing tokens heuristically. A token renewal request interval is defined based on a configurable lifetime of a token and an acquisition duration. Upon expiration of the token renewal request interval, and in the event that the token is requested by at least one client application, the authentication module renews the token with a secure token service. Renewal may also occur in the absence of a request for the token by any client application if the cached token has been kept valid for less than a threshold time. In some examples, the tokens are associated with credentials for single sign-on during site recovery management.
