| 20080256314 | CONTROLLED ANTICIPATION IN CREATING A SHADOW COPY - Controlling data retention of a collection of data in a data store. An instruction is received to store a shadow collection of data to the data store. The data store has a previous version of the shadow collection of data. An available amount of data storage space on the data store is identified. An amount of data storage space needed is estimated for storing the shadow collection of data to the data store based on the received instruction. It is determined whether the identified available amount of data storage space is sufficient for storing the estimated amount of data storage space. The shadow collection of data is stored to the data store when said determine indicates that the identified available amount of data storage space is sufficient and the previous version is permitted to be deleted or to be overwritten. | 10-16-2008 |
| 20080263551 | OPTIMIZATION AND UTILIZATION OF MEDIA RESOURCES - Method for scheduling a new backup job within a backup application to optimize a utilization of a media resource of said backup application. The backup application includes one or more previously scheduled backup jobs. The backup application calculates a current load of the media resource as a function of the previously scheduled backup jobs and the media resource and predicts a load value for the new backup job as a function of job parameters associated with the new backup job. Then, the backup application schedules the new backup job as a function of the calculated current load and the predicted load value such that the resulting load on the media resource will yeild a minimum peak percentage utilization of the media resource. Alternatively, the backup application schedules the new backup job and previously scheduled backup jobs as function of the calculated current load and the predicted load value such that the resulting load on the media resource will yield a minimum peak percentage utilization of the media resource. | 10-23-2008 |
| 20100262583 | METHOD, SYSTEM, AND APPARATUS FOR CREATING AN ARCHIVE ROUTINE FOR PROTECTING DATA IN A DATA PROTECTION SYSTEM - A method for creating an archive protection plan for archiving a backup of data is provided. An indication of an archive data protection kind and an archive data protection duration are received. In response to receiving the archive data protection kind and the archive data protection duration, an archive scheme is determined and an archive protection plan representative of the archive scheme is generated. | 10-14-2010 |
| 20110106768 | BACKUP USING METADATA VIRTUAL HARD DRIVE AND DIFFERENTIAL VIRTUAL HARD DRIVE - Methods and systems are disclosed for backup using a metadata virtual hard drive (VHD) and a differential VHD. A particular system includes a memory device that stores files and a backup agent configured to detect changes to the files. The system includes a translation module configured to translate the detected changes into VHD formatted changes and a VHD module configured to write the VHD formatted changes to a metadata VHD stored at the memory device. The VHD module is also configured to generate a differential VHD based on the metadata VHD. A network interface at the system is configured to transmit the metadata VHD and the differential VHD to a remote storage device. | 05-05-2011 |
| 20110252208 | EXPRESS-FULL BACKUP OF A CLUSTER SHARED VIRTUAL MACHINE - A computer-implemented method includes creating a first snapshot of at least one virtual machine at a first time. The first snapshot is created at a computing device of a cluster of computing devices configured to share the at least one virtual machine. As an example, each computing device in the cluster may modify the shared virtual machine via a direct input/output (I/O) transaction, bypassing a file-system stack. The first snapshot is transmitted to a backup device. The method includes creating a second snapshot of the at least one virtual machine at a second time and determining a set of changed data blocks associated with a difference between the second snapshot and the first snapshot. The set of changed blocks is transmitted to the backup device. | 10-13-2011 |

| 20090290399 | CONTENT ADDRESSABLE MEMORY BASED ON A RIPPLE SEARCH SCHEME - A scheme for ultra-low power content addressable memory based on a ripple search is disclosed. In one embodiment, a system for content addressable memory (CAM), includes a storage unit for storing a portion of content data, and a match module for comparing the portion of the content data with a respective portion of search data received by the match module. The match module includes a first static logic gate associated with a first half of the storage unit storing a sub-portion of the portion of the content data, and a second static logic gate associated with a second half of the storage unit. The first static logic gate forwards a signal for disabling the second static logic gate if the sub-portion of the portion of the content data does not match with a respective sub-portion of the portion of the search data. | 11-26-2009 |
| 20090290400 | BIT CELL DESIGNS FOR TERNARY CONTENT ADDRESSABLE MEMORY - A scheme for bit cell designs for ternary content addressable memory for comparing search data with content data is disclosed. In one embodiment, a system for comparing search data with content data stored in a ternary content addressable memory (TCAM) unit, includes a first static logic gate for comparing a first content data with a first search data, and a second static logic gate coupled to the first static logic gate for comparing a second content data with a second search data. The content data comprises the first content data and the second content data and the search data comprises the first search data and the second search data. The first static logic gate forwards a signal for disabling the second static logic gate if the first content data does not match with the first search data. | 11-26-2009 |
| 20100124089 | SINGLE-ENDED SENSE AMPLIFIER CIRCUIT - Single-ended sense amplifier circuit. An example of the sense amplifier circuit includes an inverter coupled to a bit line to read a bit cell. The sense amplifier circuit also includes a first circuit responsive to a control signal to charge the bit line for a predefined time. Further, the sense amplifier circuit includes a second circuit coupled to the bit line and responsive to a read 1 operation to retain voltage of the bit line above a first threshold to render the inverter to read 1 from the bit cell. | 05-20-2010 |
| 20110018602 | EDGE-SENSITIVE FEEDBACK-CONTROLLED PULSE GENERATOR - Edge-sensitive Feedback-controlled pulse generator. A circuit includes a pulse generating circuit responsive to a desired transition in an input signal to initiate an output pulse. The circuit also includes a delay circuit responsive to the output pulse to generate a feedback signal. Further, the circuit includes a first latch that renders the pulse generating circuit unresponsive to any change in the input signal until the feedback signal has been generated, a switch responsive to the feedback signal to complete the output pulse, a second latch responsive to a change in the input signal after the feedback signal has been generated to render the pulse generating circuit responsive to a subsequent occurrence of the desired transition in the input signal to initiate the output pulse again, and a third latch responsive to the change in the input signal after the feedback signal has been generated. | 01-27-2011 |
