The cluster should be active

Restoring is possible only if all parts of the snapshot are present in the cluster. Each node looks for a local snapshot data in the configured snapshot path by the given snapshot name and consistent node ID.
The restore procedure can be applied only to cache groups created by the user.
Cache groups to be restored from the snapshot must not be present in the cluster. If they are present, they must be link:key-value-api/basic-cache-operations#destroying-caches[ destroyed ] by the user before starting this operation.
Concurrent restore operations are not allowed. Thus, if one operation has been started, the other can only be started after the first is completed.

...

The whole cluster allowed only one cluster-wide snapshot operation per time.
Encrypted caches currently not allowed due to required additional changes to merge cache partition with its delta file.
The cache stop operation is not allowed during the ongoing cluster snapshot. An exception will be thrown to users on the cache stop attempt.
The cluster snapshot operation will be stopped if some of the baseline nodes left or fail prior to reporting about their local snapshot completion. Partial local snapshots will be reverted.
Datastructure and system caches are not included in the snapshot.
