| backup luks partition | |
| 1. Boot clonezilla | |
| 2. Drop into the command line | |
| 3. open the encrypted external drive partition | |
| cryptsetup luksOpen /dev/sda3 backup | |
| 4. mount as partimag | |
| mount /dev/mapper/backup /home/partimag | |
| 5. open the internal encrypted partitions | |
| cryptsetup luksOpen /dev/sda3 crypt1 | |
| (enter pass) | |
| cryptsetup luksOpen /dev/sdb1 crypt2 | |
| (enter pass) | |
| 6. lvm should automatically appear in /dev/mapper | |
| e.g. /dev/mapper/fedora-home | |
| /dev/mapper/fedora-root | |
| etc | |
| if not can try vgchange -ay | |
| 7. Perform backup with partclone | |
| partclone.ext4 -c -s /dev/mapper/fedora-root -o /home/partimag/backup/fedora-root-2017-09-24.img | |
| 8. When complete can restore to an image file to be able to mount and read: | |
| touch /mnt/backup/restored.img | |
| partclone.restore -C -s /home/partimag/backup/fedora-root-2017-09-24.img -O /mnt/backup/restored.img | |
| mount -t ext4 /mnt/backup/restored.img /mnt/data -o loop | |
| try to restore to a different device especially if the image is large as the data transfer speed will be halved. It took 8 hours for a 1.4TB partition that was 50% used. | |
| 9. If unable to mount image because of "ext4 bad geometry" then fix the image: | |
| e2fsck -f /mnt/backup/restored.img | |
| resize2fs /mnt/backup/restored.img | |
| then try to mount again |
