APPLICATION-CONSISTENT SNAPSHOTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240302989 titled 'APPLICATION-CONSISTENT SNAPSHOTS
The abstract describes techniques for application-consistent snapshots, including determining when a scheduled snapshot of a storage volume is imminent, initiating host buffer flushes, transferring I/O data to a write cache, and performing write cache flushes before initiating the snapshot.
- Determining scheduled snapshot of a storage volume
- Initiating host buffer flushes

Frequently Updated Research: Stay updated on advancements in data protection technologies, snapshot techniques, and disaster recovery solutions to enhance the efficiency and reliability of storage systems.
Original Abstract Submitted
described are techniques for application-consistent snapshots. the techniques include determining that a scheduled snapshot of a storage volume is imminent, where the storage volume stores input/output (i/o) data associated with an application that executes on a host server. the techniques further include initiating at least one host buffer flush prior to the scheduled snapshot being performed, where i/o data in a host buffer associated with the application is transferred to a write cache of the storage volume to reduce an amount of i/o data in the host buffer when performance of the scheduled snapshot begins. the techniques further include initiating, after the host buffer flush has completed, a write cache flush to write the i/o data in the write cache to the storage volume. the techniques further include initiating the scheduled snapshot of the storage volume in response to an indication that the write cache flush has completed.
