Kolkata: Much to the delight of the forest lovers, the state Forest department has decided to keep some selective portions of various forests in North Bengal open for the tourists from mid-June to-mid September.The entire forest area in North Bengal remains closed for tourists from June 16 to September 15 during the monsoon season. “A good number of tour operators, resort owners and transport operators had submitted a deputation last year urging department to keep certain areas in the forest open during the monsoon. Tourists have also urged our forest officials at various national parks expressing their desire to witness the natural beauty of the forest during this season. So we have decided to keep certain areas open this time,” a senior official in the state Forest department said.

According to a notification undersigned by state Chief Wildlife Warden Ravi Kant Sinha, Kalipur Jungle Camp, Dhupjhora Eco Tourism camp under Gorumara National Park, Panjhora Jungle Camp, Murti Jungle Camp, Hornbill Jungle Camp and Mouchuki Dhupjhora Eco Tourism resort, which are also located in close proximity to Gorumara will be kept open including the route in Chapramari forest from the entrance gate to the watch tower. The Dakshin Khayerbari Tiger Rescue Centre and Mendabari Jungle camp under Jaldapara National Park , the Nature Interpretation Centre at Rajabhatkhawa, Jainti, Santrabari and Buxaduar upto Buxa Fort, Poro Eco Park and Sikiajhora eco tourism centre under Buxa Forest will also remain open for the tourists. However, the department will not allow any jeep safari or elephant safari in the forest during this period. “It is essential to provide a period of least disturbance in national park and wildlife sanctuaries during rainy season for rejuvenation of flora and fauna and to maintain biodiversity in the area,” the official said.
Kubernetes v1.12 now offers alpha support for volume snapshotting. This will allow users to create or delete volume snapshots, and natively create new volumes from a snapshot using the Kubernetes API. A snapshot represents a copy of a volume at that particular instant of time. This snapshot can be used to provision a new volume that can be pre-populated with the snapshot data or to restore the existing volume to a previous state. Importance of adding Snapshots to Kubernetes The main goal of the Kubernetes team is to create an abstraction layer between distributed systems applications and underlying clusters. The layer will ensure that application deployment requires no “cluster specific” knowledge. Snapshot operations are a critical functionality for many stateful workloads. For instance, a database administrator may want to snapshot a database volume before starting a database operation. By providing a standard way to trigger snapshot operations in the Kubernetes API, users don’t have to manually execute storage system specific operations around the Kubernetes API. They can instead incorporate snapshot operations in a cluster agnostic way into their tooling and policy assured that it will work against arbitrary Kubernetes clusters regardless of the underlying storage. These snapshot primitives help to develop advanced, enterprise-grade, storage administration features for Kubernetes which includes data protection, data replication, and data migration. 3 new API objects introduced by Kubernetes Volume Snapshots: #1 VolumeSnapshot The creation and deletion of this object depicts if a user wants to create or delete a cluster resource (a snapshot). It is used to request the creation of a snapshot for a specified volume. It gives the user information about snapshot operations like the timestamp at which the snapshot was taken and whether the snapshot is ready to use. #2 VolumeSnapshotContent This object is created by the CSI volume driver once a snapshot has been successfully created. It contains information about the snapshot including its ID. This object represents a provisioned resource on the cluster (a snapshot). Once a snapshot is created, the VolumeSnapshotContent object binds to the VolumeSnapshot– with a one to one mapping- for which it was created. #3 VolumeSnapshotClass This object created by cluster administrators describes how snapshots should be created. It includes the driver information, how to access the snapshot, etc. These Snapshot objects are defined as CustomResourceDefinitions (CRDs). End users need to verify if a CSI driver that supports snapshots is deployed on their Kubernetes cluster. CSI Drivers that support snapshots will automatically install the required CRDs. Limitations of the alpha implementation of snapshots The alpha implementation does not support reverting an existing volume to an earlier state represented by a snapshot It does not support “in-place restore” of an existing PersistentVolumeClaim from a snapshot. Users can provision a new volume from a snapshot. However, updating an existing PVC to a new volume and reverting it back to an earlier state is not allowed. No snapshot consistency guarantees given beyond any of those provided by storage system An example of creating new snapshots and importing existing snapshots is explained well on the Kubernetes Blog. Head over to the team’s Concepts page or Github to find more official documentation of the snapshot feature.
