Abstract
Techniques are provided for selective snapshot creation using source tagging of input-output (I/O) operations. One method comprises receiving an I/O operation; obtaining an I/O tag associated with the I/O operation indicating a source of the I/O operation (e.g., a source application or a source virtual machine); updating a cumulative I/O tag value associated with the I/O tag that indicates an amount of activity associated with the I/O tag; and initiating a snapshot of at least a portion of a storage system that stores data associated with the I/O operation in response to the cumulative I/O tag value satisfying a corresponding threshold value. A source device associated with the I/O operation may associate the I/O tag with the I/O operation and send the I/O operation with the I/O tag to the storage system.
