Trying to backup my laptop always leads me to the same problem:
Calculating bitmap... Please wait...extfsclone.c2 bitmap error at 418 group.
Partclone fail, please check...
I did some research here and tried all fsck options of clonezilla, from live cd and recovery modus. I found no errors, but the problem remains, I can't make a backup.
Can anyone give me a hint?
I'm running ext4, xubuntu
Thanks in advance!

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
It 's a bitmap not consist issue. We need more information to find why this error in your partition. could you run dumpe2fs to get all features/metadata of the partition.
eg: sudo dumpe2fs /dev/xxx > xxx.log
the log file is a long long text, please upload the file to cloud we can access, thank you!
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
just an un init block group. a normal group of ext4 metadata. did you remember the error group is always 418 or different?
todo more debug:
1. we need partclone verbose log:
the command like: (the -d3 option will generate debug text)
sudo partclone.ext4 -d3 -c -s /dev/sda1 -o sda1.img -L sda1_verbose_ptl.log
if you catch the error again, please send the log file to us.
thank you
