mc replicate update

Parameters

ALIAS

Required

The alias of the MinIO deployment and full path to the bucket or bucket prefix on which to modify the replication rule. For example:

mc replicate update --id "c75nrap4b0talo3ipthg" [FLAGS]

--id

Required

Specify the unique ID for a configured replication rule. Use the mc replicate ls command to list the replication rules for a bucket.

--bandwidth

Optional

Limit bandwidth rates to no more than the specified rate in KiB/s, MiB/s, or GiB/s. Valid units include:

• B for bytes

• K for kilobytes

• G for gigabytes

• T for terabytes

• Ki for kibibytes

• Gi for gibibytes

• Ti for tebibytes

For example, to limit bandwidth rates to no more than 1 GiB/s, use the following:

--limit-upload 1Gi

If not specified, MinIO does not limit the bandwidth rate.

--healthcheck-seconds

Optional

The length of time in seconds between checks on the health of the remote bucket.

If not specified, MinIO uses an interval of 60 seconds.

--limit-download

Optional

Limit download rates to no more than a specified rate in KiB/s, MiB/s, or GiB/s. Valid units include:

• B for bytes

• K for kilobytes

• G for gigabytes

• T for terabytes

• Ki for kibibytes

• Gi for gibibytes

• Ti for tebibytes

For example, to limit download rates to no more than 1 GiB/s, use the following:

--limit-download 1G

If not specified, MinIO uses an unlimited download rate.

--limit-upload

Optional

Limit upload rates to no more than the specified rate in KiB/s, MiB/s, or GiB/s. Valid units include:

• B for bytes

• K for kilobytes

• G for gigabytes

• T for terabytes

• Ki for kibibytes

• Gi for gibibytes

• Ti for tebibytes

For example, to limit upload rates to no more than 1 GiB/s, use the following:

--limit-upload 1G

If not specified, MinIO uses an unlimited upload rate.

--path

Optional

Enable path-style lookup support for the remote bucket.

Valid values include:

• on - use a path lookup to find the remote bucket

• off - use a resource locator style (such as a domain or IP address) lookup to find the remote bucket

• auto - ask MinIO to identify the correct type of lookup to use to find the remote bucket

When not defined, MinIO uses the auto value.

--priority

Optional

Specify the integer priority of the replication rule. The value must be unique among all other rules on the source bucket. Higher values imply a higher priority than all other rules.

--proxy

Optional

When defining active-active replication between buckets, do not proxy.

Valid values include:

• enable - Enable proxying in active-active replication.

• disable - Disable proxying in active-active replication.

By default, MinIO defaults to enable.

--remote-bucket

Optional

Specify the credentials, destination deployment, and bucket of the remote location. Value may be an alias and bucket, location based (IP or URL), or path based.

For example, a URL based target might look like the following:

--remote-bucket https://user:secret@myminio.cloudprovider.tld:9001/bucket

An alias based target might look like the following:

--remote-bucket minio-target/my-bucket

--replicate

Optional

Specify a comma-separated list of the following values to enable extended replication features:

• delete - Directs MinIO to replicate DELETE operations to the destination bucket.

• delete-marker - Directs MinIO to replicate delete markers to the destination bucket.

• replica-metadata-sync - Directs MinIO to synchronize metadata-only changes on a replicated object back to the source. This feature only effects two-way active-active replication configurations.

  Omitting this value directs MinIO to stop replicating metadata-only changes back to the source.

• existing-objects - Directs MinIO to replicate objects created prior to configuring or enabling replication. MinIO by default does not synchronize existing objects to the remote target.

  See Replication of Existing Objects for more information.

--state

Optional

Enables or disables the replication rule. Specify one of the following values:

• "enable" - Enables the replication rule.

• "disable" - Disables the replication rule.

Objects created while replication is disabled are not immediately eligible for replication after enabling the rule. You must explicitly enable replication of existing objects by including "existing-objects" to the list of replication features specified to mc replicate update --replicate.

See Replication of Existing Objects for more information.

--storage-class

Optional

Specify the MinIO storage class to apply to replicated objects.

--sync

Optional

Enable synchronous replication for this remote target.

By default, MinIO uses asynchronous replication.

--tags

Optional

Specify one or more ampersand & separated key-value pair tags which MinIO uses for filtering objects to replicate. For example:

mc replicate update --id "ID" --tags "TAG1=VALUE&TAG2=VALUE&TAG3=VALUE"

MinIO applies the replication rule to any object whose tag set contains the specified replication tags.

Global Flags

This command supports any of the global flags.

Modify an Existing Replication Rule

Use mc replicate update to modify an existing replication rule.

mc replicate update ALIAS/PATH \
   --id ID                     \
   [--FLAGS]

• Replace ALIAS with the alias of the MinIO deployment.

• Replace PATH with the path to the bucket or bucket prefix on which the rule exists.

• Replace ID with the unique identifier for the rule to modify. Use mc replicate ls to retrieve the list of replication rules on the bucket and their corresponding identifiers.

Update the Credentials for an Existing Replication Rule

Use mc replicate update to modify an existing replication rule.

mc replicate update ALIAS/PATH \
   --id ID                     \
   --remote-bucket https://user:secret@minio.mycloud.tld:9001/mybucket

• Replace ALIAS with the alias of the MinIO deployment.

• Replace PATH with the path to the bucket or bucket prefix on which the rule exists.

• Replace ID with the updated credentials, path, and bucket.

Disable or Enable an Existing Replication Rule

Use mc replicate update with the --state flag to disable or enable a replication rule.

mc replicate update ALIAS/PATH \
   --id ID \
   --state "disable"|"enable"

• Replace ALIAS with the alias of the MinIO deployment.

• Replace PATH with the path to the bucket or bucket prefix on which the rule exists.

• Replace ID with the unique identifier for the rule to modify. Use mc replicate ls to retrieve the list of replication rules on the bucket and their corresponding identifiers.

• Specify either "disable" or "enable" to the --state flag to disable or enable the replication rule.

Required Permissions

MinIO strongly recommends creating users specifically for supporting bucket replication operations. See mc admin user and mc admin policy for more complete documentation on adding users and policies to a MinIO deployment.

S3 Compatibility

The mc commandline tool is built for compatibility with the AWS S3 API and is tested with MinIO and AWS S3 for expected functionality and behavior.

MinIO provides no guarantees for other S3-compatible services, as their S3 API implementation is unknown and therefore unsupported. While mc commands may work as documented, any such usage is at your own risk.
