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.
