Abstract: A storage manager implements adaptive snapshot chunk sizing, wherein snapshot chunks are sized differently based on an access pattern for volume data to be included in the respective snapshot chunks. For example, sequentially accessed sectors of a volume may be grouped into snapshot chunks of varying sizes and individually accessed sectors may be snapshotted as individual snapshot chunks. When a volume is populated from the snapshot chunks, the volume data is re-mapped into standard sized volume blocks. In some embodiments, an optimized manifest is generated indicting an order in which the snapshot chunks are to be used to populate a volume to perform a launch process using the volume. In some embodiments, adaptively sized snapshot chunks and a corresponding optimized manifest are used to accelerate performing a launch using a volume populated from a snapshot, such as launching an operating system, an application, a database, a machine image, etc.
