Quest Software Assigned Three Patents

Dynamic re-serialization of VTL devices and cartridges
Quest Software, Inc., Aliso Viejo, CA, has been assigned a patent (10,254,971) developed by Tripathy, Tarun K., Newark, CA, Dinkar, Abhijit, San Jose, CA, and Alvarez, Vladimir Fonseca, Brentwood, CA, for “system and method for dynamic re-serialization of VTL devices and cartridges.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Certain embodiments of the present disclosure provide systems and associated methods for dynamically re-serializing virtual tape library cartridges. The system comprises a first server node including a first virtual tape library residing on a deduplication file system, in which a backup data file corresponding to a first cartridge is stored in a first container with a first base prefix. A second server node includes a second virtual tape library residing on a second deduplication file system, and is configured to receive and store a replica of the backup data file corresponding to a second cartridge in a second container such that the second cartridge includes the same first base prefix as the first cartridge. An activation code is assigned to the second container, and used to re-serialize the first base prefix to form a second base prefix such that the second cartridge is presented with the second base prefix.”

The patent application was filed on September 2, 2016 (15/256,449).

Enhanced management of migration and archiving operations
Quest Software, Inc., Aliso Viejo, CA, has been assigned a patent (10,257,147) developed by Johnstone, Curtis T., Ottawa, Canada, and Willis, Tomas, Madison, WI, for “enhanced management of migration and archiving operations.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A network-based solution that provides enhances management of migration and archiving operations may involve, as embodied in various systems, methods, and non-transitory computer-readable storage media, performing a pre-transfer assessment on each of a plurality of accessed mailboxes designated for migration or archiving. Performing the pre-transfer assessment may include designating one or more emails for exclusion from the migration or archiving operation after applying transferability rules and exception rules to each email message contained in the assessed mailbox. The solution may involve notifying the user about the email messages designated for exclusion and performing one or more user selected actions on the email message or related attachment files.”

The patent application was filed on November 14, 2017 (15/812,908).

Content-based encryption keys
Quest Software, Inc., Aliso Viejo, CA, has been assigned a patent (10,256,978) developed by Bashyam, Murali, Fremont, CA, and Tripathy, Tarun K., Newark, CA, for “content-based encryption keys.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Techniques and mechanisms described herein facilitate the encryption of content using content-based encryption keys. According to various embodiments, data stream may include one or more data chunks. A client machine may apply a hash function to a data chunk to determine a fingerprint value. A cryptographic protocol shared with a remote server may be applied to the fingerprint value to determine a data chunk encryption key. The data chunk encryption key may be used to encrypt the data chunk, and the encrypted data chunk may be sent to the remote server for storage.”

The patent application was filed on November 7, 2017 (15/806,198).
