### Disable recovery
You can also completely disable the recovery of events and snapshots:
Scala
: @@snip [BasicPersistentBehaviorCompileOnly.scala](/akka-persistence-typed/src/test/scala/docs/akka/persistence/typed/BasicPersistentBehaviorCompileOnly.scala) { #recovery-disabled }
Java
: @@snip [BasicPersistentBehaviorTest.java](/akka-persistence-typed/src/test/java/jdocs/akka/persistence/typed/BasicPersistentBehaviorTest.java) { #recovery-disabled }
Please refer to @ref[snapshots](persistence-snapshot.md#snapshots) if you need to disable only the snapshot recovery, or you need to select specific snapshots.
In any case, the highest sequence number will always be recovered so you can keep persisting new events without corrupting your event log.
## Tagging
Persistence allows you to use event tags without using an @ref[`EventAdapter`](../persistence.md#event-adapters):
