Hi,
Do some of you use clonezilla for your backups, especially with a LVM2/LUKS
configuration please?
I've written some days ago to the clonezilla-live mailing-list but I'm not sure
I'll ever get answers considering the very very low traffic on it. So maybe
I'll be more lucky here between Debianists :)
Here is the partition configuration on my SSD:
NAME FSTYPE LABEL MOUNTPOINT
SIZE
nvme0n1
477G
├─nvme0n1p1 vfat /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 want to create a clonezilla image of everything on an external drive
partition.
So I boot on a clonezilla-live installed on a USB stick, open a shell in order
to open my LUKS container (at this stage myLvmGroup is recognized and
deployed), start clonezilla and use the ncurses interface.
Partitions like nvme0n1p{1,3,4} are backupped cleverly with
`partclone.{vfat,ext4,ntfs}` respectively. Good.
`partclone.dd` is used for nvme0n1p2 (no big deal, it's an Ms reserved
partition). OK.
However, `partclone.dd` is used as well with nvme0n1p5. Not good. This is not
very handy (it's time-consuming and produces a large file as `dd` doesn't
understand the underlying fs with the empty space).
I think this is due to the fact that my LVM is shutdowned in clonezilla before
the backup starts, as indicated in my logs:
Clonezilla image dir: /home/partimag
Shutting down the Logical Volume Manager
Shutting Down logical volume: /dev/myLvmGroup/myLvmHome
Shutting Down logical volume: /dev/myLvmGroup/myLvmRoot
Shutting Down logical volume: /dev/myLvmGroup/myLvmSwap
Shutting Down logical volume: /dev/myLvmGroup/myLvmVar
Shutting Down volume group: myLvmGroup
Finished Shutting down the Logical Volume Manager
* Do you know why there is this behavior please?
* Am I supposed to stay in shell mode and use `partclone` directly on each of
my logical volumes? Like the following maybe:
`partclone.ext4 -z 10485760 -N -L /home/partimg/partclone.log -c -s
/dev/mapper/myLvmGroup-myLvmRoot --output - | zstdmt -c -3 --rsyncable | split
-a 2 -b 4096MB - /home/partimg/myLvmGroup-myLvmRoot.ext4-ptcl-img.zst. 2>
/home/partimg/split_error.log`?
* I haven't done it so far but do you think I can use the following command
directly
`/usr/sbin/ocs-sr -q2 -c -j2 -z9p -i 4096 -fsck -enc -p choose savedisk
fulldisk_encrypted_img nvme0n1`? Or will my LVM be shutdowned as well?
* Do you have any advice to share?
Thank you in advance :)
Best regards,
