WORM (Write Once, Read Many) is the core HCP feature designed specifically for regulatory compliance and data immutability. Once data is written with a WORM retention period (e.g., 7 years), it cannot be modified, overwritten, or deleted until that period expires, even by system administrators. This is the direct technical control that enforces the legal requirement.

HCP can distribute ingest (write) operations across multiple storage pools assigned to a namespace. This load-balancing allows for parallel I/O streams, significantly improving concurrent write throughput. Adding more namespaces adds management overhead and doesn’t help a single busy namespace, while CPU and compression are less likely to be the primary bottlenecks for a write-heavy scenario tied to a single pool.

In HCP, metadata and object storage have separate quotas. The issue is specifically with metadata capacity. The immediate, non-disruptive remedy is for the tenant administrator to increase the metadata quota for their namespace(s) via the Tenant Console, provided the cluster has sufficient physical metadata capacity. This resolves the warning without impacting data or requiring cluster-level changes like adding nodes.

For S3 bucket policies (and the S3 API in general) to work, the namespace must be explicitly S3-enabled. Furthermore, S3 bucket policies are a feature of the ‘Native’ S3 authentication mode, which allows HCP to evaluate and enforce the policies itself. The ‘Legacy’ mode relies on external authentication and does not support native bucket policies.

The HCP Data Audit service runs continuously in the background. It reads stored objects, recalculates their checksums, and compares them to the checksums stored when the object was written. If a mismatch is found, HCP can automatically repair the data using other replicas. This ensures ongoing data integrity, which is a core requirement for an active archive.

The HCP Content Cache is a solid-state drive (SSD) based storage tier explicitly designed for high-performance, low-latency access to active content. It automatically caches frequently accessed objects, making it ideal for a working set of media assets that need to be retrieved quickly for editing, transcoding, or playback.

For backup data, the primary risk is premature deletion. Configuring the namespace used by Veeam with a Retention Class (setting a minimum retention period like 30 days) prevents deletion during that window. Additionally, a Hold Policy can be placed on the namespace to block all deletions until the hold is removed, offering an extra layer of safety. This is a more straightforward and enforceable method for backup immutability than relying on versioning or quotas.

HCP uses replication to ensure data durability. With a replication factor of 3, each object is stored on three different nodes. The cluster can tolerate the failure of up to two nodes without data loss, but for continuous *availability* (no interruption in read/write operations), it can typically tolerate the failure of one node. A factor of 2 only tolerates one node loss for durability and offers no availability guarantee if that node fails.

The secure and modern approach is to use S3-compatible access keys. You can create a dedicated key pair for the application and attach a granular IAM-style policy that explicitly allows only the necessary actions (e.g., s3:ListBucket, s3:GetObject) on the specific namespace/bucket. This follows the principle of least privilege, avoids sharing console passwords, and is more secure than using the namespace’s global secret key or enabling anonymous access.
