    Hello!

    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!

    Hello,

    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!

    Hello,

    I checked your log file and there is nothing special, all block from group 418 is free, no data included.

    Gruppe 418: (Blöcke 13697024-13729791) csum 0xd780 [INODE_UNINIT, BLOCK_UNINIT, ITABLE_ZEROED]
    Block-Bitmap in 13631490 (bg #416 + 2), csum 0x00000000
    Inode bitmap at 13631506 (bg #416 + 18), csum 0x00000000
    Inode-Tabelle in 13632542-13633052 (bg #416 + 1054)
    32768 freie Blöcke, 8176 freie Inodes, 0 Verzeichnisse, 8176 ungenutzte Inodes
    Freie Blöcke: 13697024-13729791
    Freie Inodes: 3417569-3425744

    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
