Encrypted image Debian system backup with Clonezilla in a LUKS/LVM2 environment
Hi,
I run Debian 10 (UEFI with Secure Boot) on multiple LVM2 partitions inside LUKS as follows:
NAME FSTYPE LABEL MOUNTPOINT SIZE
nvme0n1 477G
├─nvme0n1p1 vfat SYSTEM /boot/efi 477M
├─nvme0n1p2 16M
├─nvme0n1p3 ext4 boot /boot 477M
├─nvme0n1p4 ntfs WinRE_DRV 1000M
└─nvme0n1p5 crypto_LUKS 474,8G
└─nvme0n1p5_crypt LVM2_member 474,8G
├─myLvmGroup-myLvmSwap swap [SWAP] 14,9G
├─myLvmGroup-myLvmVar ext4 var /var 18,6G
├─myLvmGroup-myLvmRoot ext4 root / 74,5G
└─myLvmGroup-myLvmHome ext4 home /home 326G
I'm already backing up my personal data/documents (/home) via BorgBackup.
I would like now to backup my GNU/Linux SYSTEM (only) with Clonezilla and store the backup as an encrypted and compressed image on an external drive.
Do you use Clonezilla with such a similar setup?
How do you deal with LVM/LUKS please?
I asked on Clonezilla-Live mailing list but one suggested me to backup everything and choose later what I want to restore. I'm not really interested in that method because it's not optimized as I don't want to backup my /home twice (BorgBackup+Clonezilla) which is my largest partition...
Do I just need to follow this method https://gist.github.com/andyrbell/4a339c0d8a3bc9465743a6b876671dcb and iterate through /var and / (+/boot and /boot/efi outside of my LUKS)?
Do I really need a LUKS on my destination external drive like it seems to be with this method? Can't I use the Clonezilla managed encryption?
Thank you in advance for your appreciated help :)
Best regards,
