Practical commands and precautions to make a reliable backup of your UEFI "EFI System Partition" for fast recovery. 07.02.2026 | reading time: 2 min The EFI System Partition contains the bootloaders that start Linux on UEFI systems; losing it can leave a machine unbootable, so back it up deliberately and test restores. A real-world backup example Identify, mount, copy files and image the partition with common tools; run the following commands on the host and adapt device names accordingly: ```bash $ lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT sda disk 477G ├─sda1 vfat 512M /boot/efi ├─sda2 ext4 476G / $ sudo mkdir -p /mnt/efi /srv/backups/efi-files $ sudo mount -t vfat -o umask=0077 /dev/sda1 /mnt/efi $ sudo rsync -aH --delete /mnt/efi/ /srv/backups/efi-files/ $ sudo tar -czf efi-files-$(date +%F).tar.gz -C /srv/backups/efi-files . $ sudo dd if=/dev/sda1 of=efi-partition.img bs=4M status=progress && sync $ sudo sgdisk --backup=gdisk-backup.bin /dev/sda $ sudo efibootmgr -v > efi-boot-entries.txt $ sudo umount /mnt/efi ``` Sample outputs are shown above for identification; rsync finishes silently on success and `dd` shows progress lines while copying. Notes and restoration tips Use UUIDs or PARTLABELs when restoring the partition to avoid device-name mistakes; to restore a partition image recreate a matching partition then `dd` the image back, restore the GPT with `sgdisk --load-backup`, and reapply saved boot entries using `efibootmgr` or by reinstalling the bootloader if necessary. Complementary tools and strategies Protect backups with checksums such as `sha256sum`, store images in encrypted remote storage, schedule regular copies with cron or systemd timers, and prefer file-level backups with `rsync` for easy inspection plus an image backup for exact byte-level recovery when needed. Wrap-up and next steps A quick file copy is often enough to recover boot files, but combining file backups, a partition image, GPT backup and boot-entry export gives the strongest chance to recover quickly; learn the tools and practice restores regularly and consider formalizing those skills with training like bitsandbytes.academy exam preparation for CompTIA Linux+ or LPIC-1.
