Is there a way to browse through the image files?



  • Hi,

    is there a way to extract single files and folders out of the image files?

    [B]EDIT:[/B]
    I found this on the net:
    [QUOTE]partimage only copies used blocks so you need to restore to a device (in this case a block file loop mounted) – I have done this with FOG images as an experiment.[/QUOTE]

    Do these using sudo/as root if required:
    [CODE]1. gunzip image file (force suffix with -S “”)

    1. partimage imginfo <imagefile>
    2. dd if=/dev/zero of=<blockfile> bs=1024 count=0 seek=<size in GB10241024>
    3. losetup /dev/loop0 <blockfile>
    4. partimage restore /dev/loop0 <imagefile>
    5. sudo mount -t ntfs-3g /dev/loop0 /media/temp/[/CODE]

    Will this work?

    [INDENT=1]dd if=/dev/zero of=image bs=1024 count=3774771[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]where 3774771 is the number of 1K blocks. You can use “fdisk -l” on the original system to obtain the exact amount. However, I suppose you can obtain the rounded amount from partimage imginfo command and use an overestimated value;[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]2. associate this image with a loopback device, e.g.[/INDENT]
    [INDENT=1]Code: [URL=‘http://www.partimage.org/forums/viewtopic.php?t=950#’]Select all[/URL][/INDENT]
    [INDENT=1]losetup /dev/loop0 image[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]where loop0 has to be replaced with a higher numbered device (loop1, loop2, etc.) if loop0 is already in use (you can also use the -f option to use the next one available);[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]3. create a mount point, e.g.[/INDENT]
    [INDENT=1]Code: [URL=‘http://www.partimage.org/forums/viewtopic.php?t=950#’]Select all[/URL][/INDENT]
    [INDENT=1]mkdir mnt[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]4. mount the image from the loopback device, e.g.[/INDENT]
    [INDENT=1]Code: [URL=‘http://www.partimage.org/forums/viewtopic.php?t=950#’]Select all[/URL][/INDENT]
    [INDENT=1]mount -o ro /dev/loop0 mnt[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]5. and that is! You can now browse the files in the mnt directory.[/INDENT]
    [INDENT=1] [/INDENT]
    [INDENT=1]Note that steps 2-4 have to be done as superuser (root).[/INDENT]

    Hello Yoda

    I think there is one step missing, because:

    1. create an empty file
    2. connect it to a loop device
    3. create mountpoint
    4. mount loop device/file to the mountpoint
      -> 5) you see an empty filesystem :wink:

    So between 2) and 4) one has to restore the partimage image to this filesystem… right?[/QUOTE]

    Can someone tell if these steps are correct and working?
