+# HCP Vault cluster snapshot size thresholds
+
+To ensure cluster stability, performance, and reliability, HCP Vault Dedicated defines
+snapshot size thresholds for each cluster tier and size combination.
+
+
+As you increase usage of Vault resources, such as the key/value v2 (KV v2) secrets engine,
+internal storage utilization and snapshot size increase. Each tier and size combination
+supports a specific workload scale.
+
+When snapshot size grows beyond supported boundaries, cluster load increases and internal
+operations can slow down or fail.
+
+## Threshold levels
+
+Each tier and size combination has two snapshot size thresholds.
+
+### Warning threshold
+
+The warning threshold indicates that your cluster is approaching capacity limits.
+
+- The cluster may continue to function.
+- Performance degradation may begin.
+- Internal operations may slow down.
+- HCP sends an email when the warning threshold is breached.
+- HCP sends another email if usage continues to increase before the critical threshold is breached.
+- Reevaluate and redesign your usage patterns for Vault resources.
+
+### Critical threshold
+
+The critical threshold represents the maximum supported capacity.
+
+- Cluster stability is at risk.
+- Critical internal operations may fail.
+- HCP sends an email when the critical threshold is breached.
+- Backend safeguards may be triggered.
+- Some operations may be restricted, throttled, or blocked.
+
+
+| Tier | Size | Snapshot warning limit | Snapshot critical limit |
+| --- | --- | --- | --- |
+| Development | Extra small | 30 MB | 45 MB |
+| Essential | Small | 800 MB | 1 GB |
+| Essential | Medium | 2.4 GB | 3 GB |
+| Essential | Large | 6 GB | 7.5 GB |
+| Standard | Small | 1 GB | 1.2 GB |
+| Standard | Medium | 2.56 GB | 3.2 GB |
+| Standard | Large | 6.4 GB | 8 GB |
+
+## Monitor snapshot size growth
+
+Snapshot size is the primary indicator of cluster load and health. Monitor snapshot size and
+keep it within the threshold for your cluster tier and size.
+
+Snapshot size growth can be viewed from HCP Vault dashboard under the snapshots tab in the [HCP Portal](https://portal.cloud.hashicorp.com).
