"Shell script to backup MBR, GPT and data partitions (including logical ones)"

Getting Started

$ lsblk /dev/sda
NAME          MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda           259:0    0 238.5G  0 disk
├─sda1        259:1    0   199M  0 part  /boot/efi
└─sda2        259:2    0 237.7G  0 part

• Backup the /dev/sda device:

$ mkdir out
$ sudo bisk /dev/sda out
$ tree out/
out/
├── sda1.gz
├── sda2.gz
├── sda_gpt.bsc
└── sda_mbr.img

Test

• There is at your disposal a tests/test-disk.img disk image file which is partitioned as following (including the logical volumes into test-disk.img4):

$ fdisk -l test-disk.img
[...]
Device          Start    End Sectors Size Type
test-disk.img1   2048  69631   67584  33M Microsoft basic data
test-disk.img2  69632  90111   20480  10M Linux filesystem
test-disk.img3  90112 110591   20480  10M Linux swap
test-disk.img4 110592 131038   20447  10M Linux filesystem

• After mounting the disk image file, you will obtain:

# lsblk -f -p -o NAME,FSTYPE /dev/loop1
NAME                            FSTYPE
/dev/loop1
├─/dev/loop1p1                  vfat
├─/dev/loop1p2                  ext4
├─/dev/loop1p3                  swap
└─/dev/loop1p4                  LVM2_m
  ├─/dev/mapper/test-disk-home  ext4
  └─/dev/mapper/test-disk-root  ext4

• Run the test script as following:

$ cd tests
$ sudo ./test.sh

• Results:
