mc replicate reset

mc replicate resync

Syntax

The mc replicate resync command resynchronizes all objects in the specified MinIO bucket to a remote replication <minio-bucket-replication-serverside> 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:

• minio-bucket-replication-serverside-twoway
• minio-bucket-replication-serverside-multi

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

Parameters

ALIAS

The alias <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

Starts the resynchronization procedure using the specified bucket <mc replicate resync ALIAS> as the source and the --remote-bucket <mc replicate resync --remote-bucket> as the remote target.

Mutually exclusive with mc replicate resync status.

status

Returns the status of resynchronization on the specified bucket <mc replicate resync ALIAS> to all remote targets.

Include the ~mc replicate resync --remote-bucket argument to filter the status output to only the specified remote target.

--remote-bucket

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

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

Only valid with mc replicate resync start.

Global Flags

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