## Volume Snapshots

A volume snapshot is a read-only, point-in-time copy of a storage volume. It preserves the state of the volume at the
moment the snapshot is taken, allowing users to restore data or create new volumes based on the captured state.
Snapshots are typically implemented using copy-on-write (COW) or redirect-on-write (ROW) techniques, minimizing storage
overhead and improving efficiency.
In simplyblock, a volume snapshot can be taken instantly. It contains the read-only (frozen) state of the volume at the
time it was taken, while the source volume then operates with Copy-on-Write (CoW) semantics.

Multiple snapshots can coexist for a particular volume, representing different frozen generations or versions of that
volume, and they are ordered in time (a snapshot references the changed data delta between its predecessor and its
successor).

Volume snapshots can be independently deleted, backed up to S3, and replicated into other clusters. New volumes can be
created from any Snapshot (copy-on-write cloning).

A volume clone is a writable, independent copy of a storage volume created from either an existing volume or a
snapshot. Unlike snapshots, clones are fully functional duplicates that can operate as separate storage entities.
