What does cloning in storage mean?

Cloning in storage means creating a writable copy of a volume or LUN that initially shares data blocks with the source and becomes independent as you write to it. This is usually done with a copy-on-write approach: both the clone and the original start by referencing the same blocks, and when you write to the clone, new blocks are allocated so the two diverge. The advantage is you get a usable copy without duplicating all data upfront, which is ideal for testing, development, or fast backups with minimal storage impact. It isn’t about real-time replication to another site, which would be continuous mirroring; it isn’t about moving data between performance tiers, and it isn’t about caching data in RAM to speed access.
