How to Install DREBS on NetBSD

DREBS is a tool for backing up and restoring AWS EBS volumes. In this tutorial, we will guide you through the steps to install DREBS on NetBSD.

Prerequisites

• A NetBSD system
• Git installed on your system
• Java installed on your system

Steps

1. Open the NetBSD terminal

2. Install Git by running the following command:

   pkg_add git
   

3. Clone the DREBS repository from GitHub with the following command:

   git clone https://github.com/dojo4/drebs.git
   

4. Navigate to the cloned repository:

   cd drebs
   

5. Open the build.gradle file:

   vi build.gradle
   

6. Scroll down to find the following line:

   def targetPlatforms = ["macosx-10.8-x86_64", "linux-x86_64", "windows-x86_64", "freebsd-amd64"]
   

7. Add netbsd-amd64 at the end of the list, separated by a comma.

   def targetPlatforms = ["macosx-10.8-x86_64", "linux-x86_64", "windows-x86_64", "freebsd-amd64", "netbsd-amd64"]
   

8. Save and exit the file by pressing Esc and then entering :wq.

9. Install Gradle with the following command:

   pkg_add gradle
   

10. Build the DREBS package:

    gradle distZip
    

11. If the build succeeds, you will find a zip file in the build/distributions directory. Extract the zip file:

    unzip build/distributions/drebs-<version>.zip -d /opt/drebs
    

    Note: Replace <version> with the version number of the DREBS package you built in step 10.

12. Configure DREBS by creating a config.json file in the /opt/drebs/bin directory:

    cd /opt/drebs/bin
    touch config.json
    

13. Open and edit the config.json file:

    vi config.json
    

14. Add the following contents into the file:

    {
      "accessKeyId": "<Your AWS Access Key ID>",
      "secretAccessKey": "<Your AWS Secret Access Key>",
      "region": "<Your preferred region>",
      "snapshotSize": 1000,
      "snapshotAge": 14
    }
    

    Note: Replace <Your AWS Access Key ID>, <Your AWS Secret Access Key>, and <Your preferred region> with your own values. The snapshotSize specifies the maximum size of EBS volumes to be backed up, in GB. The snapshotAge specifies the maximum age of EBS volumes to be backed up, in days.

15. Save and exit the config.json file.

16. Test DREBS by running the following command:

    ./drebs backup -v <EBS Volume ID>
    

    Note: Replace <EBS Volume ID> with the ID of the EBS volume you want to back up.

17. If the backup is successful, congratulations! You have successfully installed DREBS on NetBSD.

Conclusion
