Persistent Local Mount at Boot

Objective: Mount a disk persistently using /etc/fstab so it automatically mounts at boot.

• 1. Create Mount Point

  sudo mkdir -p /backups

  

• 2. Identify Device to Mount

  lsblk

  Check available devices to find the one you want to mount.

  

• 3. Mount Device Temporarily

  sudo mount /dev/sdb1 /backups

  Verify the mount:

  lsblk

  

• 4. Add Device to /etc/fstab

  sudo blkid /dev/sdb1
  sudo nano /etc/fstab

  Example fstab entry using UUID:

  UUID=your-uuid-here  /backups  ext4  defaults,nofail  0  2

  • defaults – default mount options
  • nofail – system still boots if device is missing
  • 0 – do not dump
  • 2 – fsck order (non-root filesystem)
  

• 5. Verify fstab Configuration

  sudo mount -a

  If no errors appear, fstab is correctly configured.

  

• 6. Reboot and Confirm Persistent Mount

  sudo reboot
  lsblk

  Ensure the device is still mounted at /backups after reboot.
