Patent number: 10282201Abstract: Systems and methods are provided for automating a provision of applications from a source to a target by providing a virtual copy of application data, wherein the virtual copy can be adapted to a plurality of different target environments. Versions of source application data from an application database at a source production server are maintained at times associated with a schedule. Data associated with a request is received from a user to provision the source application data for a target environment at a target server, the request further comprising application specific parameters that define necessary requirements for the target environment. A virtual copy of the source application data is presented to the target server. Instructions to the target server are transmitted that define how to restore an operational server database from the virtual copy based on the application specific parameters to meet the requirements of the target environment.Type: GrantFiled: April 29, 2016Date of Patent: May 7, 2019Assignee: Actifo, Inc.Inventors: Uday Tekade, Xiangdong Zhang, Sachindra Kumar, Madhav Mutalik, Yeganjaiah Gottemukkula, Yong-Min Chen, Ankur Bhargava, Dongjun Sun

Patent number: 10055300Abstract: Systems and methods for backing up clustered databases such that production backups associated with the clustered databases are restorable with near zero downtime. First data indicative of a backup request of a clustered database is transmitted by a first computing device to a second computing device. The first computing device maps the backup staging disks to each of a plurality of nodes. The second computing device adds the mapped staging disks to a backup staging diskgroup on a primary node. The second computing device mounts the backup staging diskgroup to each of the plurality of nodes. The second computing device executes a full backup from at least one of the plurality of nodes to the backup staging diskgroup. The second computing device transmits a catalog of backup information to a database associated with the first computing device. The first computing device creates a snapshot of the first backup staging disk.Type: GrantFiled: January 12, 2016Date of Patent: August 21, 2018Assignee: Actifio, Inc.Inventors: Xiangdong Zhang, Madhav Mutalik, Satya Sri Kanth Palaparthi, Yeganjaiah Gottemukkula, Sachindra Kumar, Uday Tekade

Patent number: 10013313Abstract: Systems and methods of performing backup of databases and associated logs with one schedule such that a backup of both a database and its associated log can be restored or recovered to a desired point in time. A backup request associated with a backup type is received and defined by a service level agreement. The service level agreement includes a combined schedule for backing up both data stored in the database and log data associated with a database.Type: GrantFiled: September 16, 2015Date of Patent: July 3, 2018Assignee: Actifio, Inc.Inventors: Xiangdong Zhang, Uday Tekade, Sachindra Kumar, Madhav Mutalik

Patent number: 9658771Abstract: A computer implemented user interface which enables a user to input alphabets in at least one Indian language is disclosed herein. The user interface includes a display enabled keypad layout which in turn includes a default keypad layer, a first keypad layer, a second keypad layer and a third keypad layer. The default keypad layer comprises a plurality of alphabets represented as selectable vowels and consonants. The first keypad layer comprises the vowels and consonants, and a plurality of modifiers. The second keypad layer comprises a plurality of matras, a plurality of halants, the vowels, and the consonants. The third keypad layer comprises the matras and the modifiers. The keypad layers are configured to be incorporated onto the display enabled keypad layout and selectively displayed, based on at least the selection of a key on at least one of the keypad layers.Type: GrantFiled: August 29, 2014Date of Patent: May 23, 2017Assignee: REVERIE LANGUAGE TECHNOLOGIES PVT LTDInventors: Vivekananda Pani, Sachindra Kumar Mohanty

Patent number: 9495435Abstract: Systems and methods are provided for backing up database storage. A protection policy for database storage is activated at a remote host, wherein the database storage is not physically accessible by the computing device, such that the out-of-band storage is not in communication with the remote host through the computing device. A backup request is transmitted to the remote host comprising data indicative of a volume on the database storage to back up according to the protection policy. A response to the backup request is received comprising staging disk requirements including a required size for a staging disk. A staging disk is determined based on the response. The staging disk is presented to the remote host so that the remote host can perform a backup of the volume to the staging disk using a database backup tool provided by a vendor of the database storage.Type: GrantFiled: June 18, 2013Date of Patent: November 15, 2016Assignee: ACTIFIO, INC.Inventors: Xiangdong Zhang, Madhav Mutalik, Sachindra Kumar
