AIStor can make the loss of an entire site, while significant, a relatively minor incident. Site recovery depends on the replication option you use for the site. Replication type Restoration method Site Replication Total restoration of IAM configurations, bucket configurations, and data from the healthy peer site(s) Bucket Replication Data restoration of objects and metadata from a healthy remote location for each bucket configured for replication mc mirror Data restoration of objects only from a healthy remote location with no versioning Site replication healing automatically adds IAM settings, buckets, bucket configurations, and objects from the existing site(s) to the new site with no further action required.

AIStor provides tools for scaling your cluster capacity by adding or removing server pools. These tools allow you to expand storage capacity or retire aging hardware without disrupting ongoing operations. Planning for growth MinIO recommends initially sizing clusters for at least 2-3 years of anticipated data growth. This approach minimizes the frequency of expansion operations and simplifies long-term capacity management.

Each AIStor server process exposes unauthenticated endpoints for probing server uptime and deployment high availability for simple healthchecks. These endpoints return an HTTP status code indicating whether the underlying resource is healthy or satisfies read/write quorum. The server exposes no other data through these endpoints. AIStor liveness Use the following endpoint to test if the specified AIStor server is up and ready to serve requests:

AIStor requires an active and unexpired MinIO Commercial License. Use mc license info to check your current license status. Accessing your license The license is available in MinIO SUBNET. Log in to SUBNET. From the Deployments screen, select License Key.

Description The mc admin prometheus command and its subcommands provide access to MinIO Prometheus metrics. Subcommands Subcommand Description generate The mc admin prometheus generate command generates a metrics scraping configuration file for use with Prometheus. metrics The mc admin prometheus metrics command prints Prometheus metrics for a cluster.

The mc admin cluster bucket export command exports bucket metadata for use with the (mc admin cluster bucket import) command. You can use this command to manually back up the metadata for the specified AIStor bucket. The command always saves the output as cluster-metadata.zip. If you specify only the deployment as the target, this command backs up all bucket metadata on the target deployment.

Description The mc admin cluster bucket command and its subcommands provide tools for manually importing and exporting AIStor bucket metadata. This metadata includes configurations related to features like lifecycle management rules. You can use this metadata as a snapshot of the bucket configuration for restoration later, such as part of or backup/restore operations.
