Techniques to back up data associated with a cluster environment are disclosed. In various embodiments, an indication is received to back up data associated with the cluster. A backup configuration data associated with the cluster is used to back up, in a unified backup operation, one or more save sets associated with virtual resources associated with the cluster and one or more saves sets associated with physical nodes associated with the cluster, including by storing each respective save set in a manner that associates the save set with a virtual or physical node comprising the cluster suite.

Unified protection of cluster suite

Techniques to back up a cluster resource are disclosed. In various embodiments, an active cluster node is used to take and store persistently on a cluster shared volume a snapshot of the cluster shared volume. The persistent snapshot is used to back up the cluster shared volume, including by storing checkpoint information indicating as the backup progresses which portions of the snapshot have been backed up. A cluster environment with which the cluster shared volume is associated is monitored to detect any failover or failback affecting the backup.

Data protection using checkpoint restart for cluster shared resources

A method for recovering data from one or more storage systems for a group recovery. In response to receiving a request for the group recovery, the method implemented at a backup server identifies a group recovery resource based on the request, where the group recovery resource includes one or more recovery item lists. The backup server traverses the one or more recovery item lists of the group recovery resource to determine a source recovery storage system, target recovery storage systems, and one or more data items to be recovered to each of the target recovery storage systems. The backup server then initiates one or more recovery sessions to recover the one or more data items from the source recovery storage systems to the recovery target storage systems substantially concurrently.

Method and system for performing group recovery from a recovery source to multiple recovery targets

Techniques to back up a cluster shared volume (CSV) are disclosed. In various embodiments, a snapshot of the cluster shared volume is stored persistently on the cluster shared volume itself. A task to back up a corresponding assigned portion of the snapshot is assigned to each of one or more cluster servers available to participate in backing up the cluster shared volume. The cluster servers have shared access to the snapshot as stored on the cluster shared volume, and each is configured to perform the task assigned to it in parallel with any other cluster servers assigned to back up other portions of the same cluster shared volume snapshot. The respective assigned tasks are monitored to completion.

Parallel node backup for CSV

Instant invention is about a hand held micro PCR device comprising a LTCC micro PCR chip comprising a heater, a reaction chamber to load a sample. It also comprises a heater control to regulate the heater on basis of input received from a temperature sensor. It further has an optical system having an optical fiber to detect a fluorescence signal from the sample, and at least one communication interface to interact with other device(s).

Hand held micro PCR device including microcontroller for exchanging information with a communications interface

Instant invention is about a micro chip comprising plurality of layers of LTCC wherein a reaction chamber is formed in plurality of top layers to load samples. A heater embedded in at least one of the layers below the reaction chamber and a temperature sensor is embedded in at least one of the layers between the heater and the reaction chamber for analyzing the sample. The temperature sensor can be placed outside the chip to measure the chip temperature.
