Integrate Restic with IDrive® e2

Restic is a modern, free, and open-source backup tool that can easily back up Linux, BSD, Mac, and Windows to different storage options, including self-hosted and online services. It ensures that your files can be restored when needed. You can configure Restic with IDrive® e2 hot Cloud Storage using the S3 compatible API. Learn more about Restic.

Prerequisites:

Before uploading files using Restic, you require:

  1. An active IDrive® e2 account. Sign up here if you do not have one.
  2. A bucket in IDrive® e2. See how to create a bucket.
  3. A valid Access Key ID and Secret Access Key. Learn how to create an access key.
  4. Restic should be installed on your system.

Install Restic

  1. Use the following commands to install Restic based on your operating system:
    1. Ubuntu/Debian 
      #sudo apt install restic
    2. Redhat/CentOS 
      #sudo yum install restic
    3. macOS 
      #brew install restic
  2. Run the command to ensure that Restic is on the latest version:
    1. #restic self-update

Configure Restic with IDrive® e2

To simplify the use of Restic, IDrive® e2 recommends you keep Restic environment variables that you need in a file, for e.g. /etc/restic-env

  1. Save the following environment variables into the file "/etc/restic-env" 
     export AWS_ACCESS_KEY_ID=<e2_access_key_id>
     export AWS_SECRET_ACCESS_KEY=<e2_secret_access_key>
     export RESTIC_REPOSITORY="e2_s3_endpoint/e2_bucket" (Ex: s3:https://u6a5.bn.idrivee2-61.com/restic)
     export RESTIC_PASSWORD_FILE=/etc/restic-password

    2. Note: Create file "/etc/restrict-password" and that file should contain one line with password (Ex: e2IDriveSecure)

  2. Secure the Restic files by changing ownership so that only "root/user" can see the files: 
     #chown root:root /etc/restic-env
     #chown root:root /etc/restic-password
     #chmod 700 /etc/restic-env
     #chmod 700 /etc/restic-password
  3. Before you run any Restic commands, load the Restic environment variables with the following command so that Restic variables are always defined: 
    #source /etc/restic-env
  4. Initialize the repository 
    #restic -r s3:https://u6a5.bn.idrivee2-61.com/e2restic init

    In response, it will ask to set a Password for repository
    Enter password for new repository and confirm the password

  5. You will receive the following response after submitting the password created restic repository 7c81e95555 at s3:https://u6a5.bn.idrivee2-61.com/e2restic

    6. Note: You must know your password to access the repository. Losing your password means that your data is irrecoverably lost.

Create Backup

To backup the local directory to the IDrive® e2 bucket using Restic, use the following example:

#restic -r s3:https://u6a5.bn.idrivee2-61.com/e2restic backup /home/test/Downloads/data/

OR

If you have defined the "RESTIC_REPOSITORY" variable, then you do not need to add s3:https://u6a5.bn.idrivee2-61.com in the Restic command. Refer to the following example:

#restic backup /home/test/Downloads/data/
Response:
