# Duplicati

[Duplicati](http://duplicati.com/) is an open-source backup service. It allows you to remotely manage backups from multiple devices using a web-based graphical interface. It supports S3, FTP, SFTP, OpenStack Swift, and WebDAV protocols.

## Configure backup in Duplicati \{#configure-backup-to-duplicati}

1. [Create a bucket for backups](#create-backup-bucket).
2. [Configure S3 access](#configure-s3-access).
3. Optional: to further protect your backups, [enable versioning and Object Lock](#enable-versioning-and-object-lock).
4. [Install Duplicati](#install-duplicati).
5. [Create a backup plan](#create-backup-plan).
6. [Check the backup plan execution](#check-backup-plan-execution).

### 1. Create a bucket for backups \{#create-backup-bucket}

Use the [Create a bucket](/s3/buckets/create-bucket.mdx) guide.

### 2. Configure S3 access \{#configure-s3-access}

<GrantAccess />

### 3. Optional: enable versioning and Object Lock \{#enable-versioning-and-object-lock}

1. If you want to store and, if necessary, restore previous versions of objects with backups, [enable versioning](/s3/buckets/versioning.mdx).
2. If you want to block backups in a bucket from accidental deletion or overwriting, in addition to versioning:

   2.1. [Enable Object Lock](/s3/buckets/object-lock.mdx#enable-object-lock).

   2.2. [Enable default object retention](/s3/buckets/object-lock.mdx#enable-default-retention).

### 4. Install Duplicati \{#install-duplicati}

Use the [Installation](https://docs.duplicati.com/getting-started/installation) section of the Duplicati documentation.

### 5. Create a backup plan \{#create-backup-plan}
