 Note that a limitation of the local storage is that it is not clustered or replicated. Thus, it is not arbitrarily scalable or durable in the face of disk or node outages and should be treated as you would any other kind of single node database. Using RAID for disk availiablity, [snapshots](https://prometheus.io/docs/prometheus/latest/querying/api/#snapshot) for backups, capacity planning, etc, is recommended for improved durability. With proper storage durability and planning storing years of data in the local storage is possible.
 
-Alternatively, external storage may be used via the [remote read/write APIs](https://prometheus.io/docs/operating/integrations/#remote-endpoints-and-storage). Careful evaluation is required for these systems as they vary greatly in durability, performance, and efficency.
