  • Publication number: 20250138956
    Abstract: In general, in one aspect, the technology relates to a method for backing up assets, the method comprising obtaining a group identifier (ID) associated with an asset, associating the asset with an asset group using the group ID, wherein all assets in the asset group are associated with the group ID, and protecting the asset in the asset group using a backup strategy associated with the asset group.

  • Publication number: 20240202909
    Abstract: A method for detecting word line shorts in a memory device includes: determining a region of interest (ROI) region in a bright voltage contrast (BVC) image for contact through-holes (CTs) of word lines in the memory device, the CTs comprising first CTs in at least one first word line that is electronically charged and second CTs in at least one second word line that is not electronically charged, and the ROI region comprising the at least one first word line; determining coordinates of each CT in the ROI region; reviewing a grayscale value at a position of the coordinates of each CT in the ROI region to determine whether the CT is a defective CT; and displaying the defective CT in response to the defective CT being determined.

  • Patent number: 12007847
    Abstract: Techniques described herein relate to a method for reporting database backup information. The method may include starting a monitor process; generating a flag file for the database backup comprising a parent process identifier (PID) of a parent process of a first child process; associating a second child process with the monitor process by identifying the flag file using the parent PID; receiving channel close alerts from the child processes; making a first determination that backup jobs performed in a first channel were successful; making a second determination that backup jobs performed in the second channel were successful; and transmitting, based on the first determination and the second determination, a backup success report to a backup coordinator.

  • Publication number: 20240177295
    Abstract: A method of locating contact through-hole (CT) positions in a memory device includes: obtaining a bright voltage contrast (BVC) image including a plurality of CTs in the memory device; determining CT coordinates in the BVC image; validating the CT coordinates in the BVC image based on a golden CT layout to obtain validated CT coordinates in the BVC image; and locating the CT positions in the memory device based on the validated CT coordinates in the BVC image.

  • Patent number: 10976952
    Abstract: A remote agent for providing backup services to applications includes a persistent storage and a backup manager. The persistent storage stores backup policies for the applications. The backup manager identifies an application of the applications for providing the backup services; generates an application backup template based on a backup policy of the backup policies for the application; sends the generated application backup template to a production host that hosts the application; and makes a determination that the backup policy has been triggered. In response to the determination, the backup manager initiates a native data extraction from the application using the application backup template to obtain a native data dump; stores the native data dump in backup storage; and indexes the stored native data dump as a backup.
