How Does IBM Flash Copy Create Point-in-Time Data Copies?
The process of creating point-in-time data copies using IBM Flash Copy is one of the key aspects of this technology. This mechanism enables fast and efficient recording of data state at a specific moment, which is essential for later recovery.
Flash Copy works by creating so-called snapshots, which are logical copies of data stored on disks. At the moment of snapshot creation, the system records the state of data at the block level, which means that every change in data is tracked and recorded. This enables quick data restoration to the state from the moment of snapshot creation, without the need to physically copy all data.
The differential technique used by Flash Copy means that after creating a snapshot, the system records only changes in data, not entire data. This significantly reduces the amount of stored data and speeds up the copy creation process. Each snapshot is created in a fraction of a second, enabling minimal disruptions in system operation.
Thanks to this approach, IBM Flash Copy is an ideal solution for companies that need a quick and reliable way to create data backups and recover them in case of failure. Snapshots can also be used for testing and development purposes, further increasing their value for organizations.
