In this document we will illustrate how to set up replication between two Minio servers, `minio1` and `minio2` running on ``192.168.1.11`` and ``192.168.1.12`` respectively. We will mirror the data directory on `minio1` to the bucket on `minio2`.

Cron is a Unix/Linux system utility by which you can schedule a task process for particular duration, we have tested this setup on Ubuntu Linux. Cron is a Unix/Linux system utility by which you can schedule a task process for particular duration, we have tested this setup on Ubuntu Linux.

Add crontab configuration on `minio1` providing path of data directory, ``minio1-data``. Add crontab configuration on `minio1` providing path of data directory, ``minio1-data``.
``--force`` option with ``mc mirror`` overwrites the destination contents, this would keep your contents in sync. ``--force`` option with ``mc mirror`` overwrites the destination contents, this would keep your contents in sync.

Note: We are going to introduce continuous replication feature in `mc mirror` which will enable the sites to be in sync without having the need to setup cron job.
