I just tried to use the copy of clonezilla-1.2.6-40 that is included in PartedMagic 5.9 (http://partedmagic.com/doku.php?id=changelog )

I received an error when trying to backup several partitions using the parallel bzip2 option from the compression choices menu. The error was:

pbzip2: Bad flag `-b1024'

followed by the valid flags for pbzip2 1.0.6. '-b' is apparently not a valid flag anymore.

I looked at the changelog for Clonezilla live 1.2.6-59 (the one release since Clonezilla 1.2.6-40) and saw no mention of this bug being fixed. I have not tried 1.2.6-59, but believe there is a good chance the bug is not fixed in it because the changelog says nothing about it and could find no discussion about it in the forums or bug tracker.

When I went back through the same steps but selected regular bzip2 (not parallel) things worked fine albeit slower.

    Further research tells me that there are two versions of pbzip2 out there.

    One by Julian Seward:
    http://bzip.org/
    http://bzip.org/CHANGES
    current version 1.0.6 dated Sept 20, 2010. Previous update was in Dec 2007.
    man page does not show any -b option

    One by Jeff Gilchrist:
    compression.ca
    current version 1.1.1 dated April 17, 2010. Has had more frequent updates.
    man page shows the -b option
    http://compression.ca/pbzip2/

    Did clonezilla switch pbzip versions without a note in the changelog? Or is this an integration problem with PartedMagic where PartedMagic was using the other version of pbzip2?

    pbzip2 stands for "parallel bzip2" - it builds on top of bzip2.

    Actually -b# option is a valid option for current pbzip2 release (1.1.x). Which pbzip2 version is bundled with the mentioned Clonezilla versions?

    javor_nik,
    Thanks for explaining that. Both Clonezilla live 1.2.6-40 and 1.2.7-11 include pbzip2 1.1.1. Therefore there is no such issue.

    Haudy,
    You should file report this bug to PartMagic. In PartMagic 5.9 I found the pbzip2 is linked to bzip2.
    You can see that by running:
    ls -alFh /bin/bzip2
    While in Clonezilla if you choose to use parallel bzip2, it will use pbzip2 instead of bzip2.

    Steven.
