Backup System Drive to Mega.nz

Automate your Linux system drive backup process, sending it directly to your Mega.nz account using the backup-system-drive-to-meganz script.

Prerequisites

  • You need to have megacmd already working in your system:

    • Download the repo from mega.nz linux repo
    • If you're only in the command line, you can use curl. For example:
      curl -O https://mega.nz/linux/repo/xUbuntu_23.04/amd64/megacmd_1.6.3-1.1_amd64.deb
      
    • Choose your system and run the command with the proper path from here.
    • For more details, you can check their GitHub repo: MEGAcmd GitHub.
  • After installation, try to login. Check out their manual on GitHub: MEGAcmd User Guide. Ensure that megacmd is working at this point.

Setup

  1. Determine System Drive Device Name:

    • Run lsblk -o NAME,TYPE,MOUNTPOINT to check your system drive device name. Look for drives that have some partitions with names like boot or boot/efi.

      Example Output:

      nvme3n1                   disk
      ├─nvme3n1p1               part  /boot/efi
      ├─nvme3n1p2               part  /boot
      └─nvme3n1p3               part
        └─ubuntu--vg-ubuntu--lv lvm   /
      

      In this case, the proper name for the system drive will be /dev/nvme3n1.

  2. Script Placement:

    • Place system_backup_to_mega.sh in a directory only accessible by the root user.
    • Run chmod +x /path/to/system_backup_to_mega.sh to make the script executable.
  3. Modify the Script:

    • Edit the script to set your credentials, disk drive path, and folders for temporary backups.

      nano system_backup_to_mega.sh
  4. Run Manually:

    • Execute the script manually using:

      sh system_backup_to_mega.sh
    • Monitor active processes in another terminal window to ensure everything is running correctly. Use bashtop or similar tools to do so.

  5. Automate with CRON:

    • If everything works correctly and you can see your backup file in your Mega.nz account, you can automate the backup process using CRON:

      crontab -e
    • Add a new line to execute the script every day at 3 am:

      0 3 * * * ~/path/to/system_backup_to_mega.sh
  6. CRON Timing:

    • If you're unfamiliar with setting up CRON timings, you can use online tools like CronTab or simply ask here for guidance.

Note

Using this script, your system will automatically create a backup of your drive and upload it to your Mega.nz account. Always ensure to test backup scripts in a controlled environment before deploying to ensure data integrity and prevent data loss.
