Creating a Volume Snapshot

Create volume snapshot manually via Data Fabric UI.

Prerequisites

  • You must be a fabric user to create a volume snapshot.

About this task

A snapshot is a read-only image of a volume that provides point-in-time recovery of the volume if data on the volume gets corrupted or is lost due to some reason. Snapshots store changes to the data present in the volume. A snapshot preserves access to historical data and facilitates data retrieval, when data is lost due to user errors and application errors.

You can create a snapshot manually, or automate the process with a schedule. Snapshots are stored in the .snapshots directory. You can always view snapshots from this directory.

The maximum number of snapshots that you can create for each volume is 4092. Exceeding this limit raises the snapshot failure alarm with an appropriate entry in the CLDB logs.

Follow the steps given below to create a snapshot manually via the Data Fabric UI.
