Syntax

The mc replicate resync command resynchronizes all objects in the specified MinIO bucket to a remote replication target.

This command requires first configuring the remote bucket target using the mc admin bucket remote add command. You must specify the resulting remote ARN as part of running mc replicate resync.

This command supports rebuilding a MinIO deployment using an active-active replication remote as the “backup” source. See the following tutorials for more information on active-active replication:

EXAMPLE

The following command resynchronizes the content of the mydata bucket on the myminio MinIO deployment to the remote MinIO deployment associated to the specified --remote-bucket:

mc replicate resync start \
   --remote-bucket "arn:minio:replication::d3c086c7-1d64-40c2-954b-fe8222907033:mydata" \
   myminio/mydata

SYNTAX

The command has the following syntax:

mc [GLOBALFLAGS] replicate resync start|status  \
                 --remote-bucket "string"       \
                 [--older-than "string"]        \
                 ALIAS

Brackets [] indicate optional parameters.
Parameters sharing a line are mutually dependent.
Parameters seperated using the pipe | operator are mutually exclusive.

Copy the example to a text editor and modify as-needed before running the command in the terminal/shell.

The alias of the MinIO deployment and full path to the bucket or bucket prefix which MinIO uses as the replication source. For example, the following command starts replication using the data bucket on the MinIO deployment associated to the primary alias.

mc replicate resync start primary/data --remote-bucket "ARN"

start

Required

Starts the resynchronization procedure using the specified bucket as the source and the --remote-bucket as the remote target.

Mutually exclusive with mc replicate resync status.

status

Required

Returns the status of resynchronization on the specified bucket to all remote targets.

Include the --remote-bucket argument to filter the status output to only the specified remote target.

--remote-bucket

Required

Specify the ARN for the destination deployment and bucket. You can retrieve the ARN using mc admin bucket remote:

Use the mc admin bucket remote ls to retrieve a list of ARNs for the bucket on the destination deployment.
Use the mc admin bucket remote add to create a replication ARN for the bucket on the destination deployment.

older-than

Optional

Specify a duration in days where MinIO only resynchronizes objects older than the specified duration.

Only valid with mc replicate resync start.

Global Flags

--debug

Optional

Enables verbose output to the console.

For example:

mc --debug COMMAND

--config-dir: Optional
The path to a JSON formatted configuration file that mc uses for storing data. See Configuration File for more information on how mc uses the configuration file.

--JSON

Optional

Enables JSON lines formatted output to the console.

For example:

mc --JSON COMMAND

--no-color: Optional
Disables the built-in color theme for console output. Useful for dumb terminals.

--quiet: Optional
Suppresses console output.

--insecure: Optional
Disables TLS/SSL certificate verification. Allows TLS connectivity to servers with invalid certificates. Exercise caution when using this option against untrusted S3 hosts.

--version: Optional
Displays the current version of mc.

--help: Optional
Displays a summary of command usage on the terminal.

Examples

Resynchronize Remote Replication Target from Source Bucket

The following mc replicate resync command resynchronizes all objects on the specified source bucket to the remote target regardless of their replication status:

mc replicate resync start --remote-bucket "arn:minio:replication::UUID:data" primary/data

Replace primary/data with the ALIAS and full bucket path for which to create the replication configuration.
Replace the --remote-bucket value with the ARN of the remote target. Use mc admin bucket remote ls to list all configured remote replication targets.

Behavior

S3 Compatibility

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