@ -46,12 +46,14 @@ A snapshot contains a copy of the on-disk data structures that make up an
index. This means that snapshots can only be restored to versions of
Elasticsearch that can read the indices:
* A snapshot of an index created in 6.x can be restored to 7.x.
* A snapshot of an index created in 5.x can be restored to 6.x.
* A snapshot of an index created in 2.x can be restored to 5.x.
* A snapshot of an index created in 1.x can be restored to 2.x.
Conversely, snapshots of indices created in 1.x **cannot** be restored to 5.x
or 6.x, and snapshots of indices created in 2.x **cannot** be restored to 6.x.
or 6.x, snapshots of indices created in 2.x **cannot** be restored to 6.x
or 7.x, and snapshots of indices created in 5.x **cannot** be restored to 7.x.
Each snapshot can contain indices created in various versions of Elasticsearch,
and when restoring a snapshot it must be possible to restore all of the indices
