Whats the difference between both of the file formats. The reason I asked is because I have two DD images, both above 4GBs, lets say
I understand that Tar is a method of creating [tape] archives and bz2 is Bzip2 which uses compression. So one file is a compressed tape archive [.tar.bz2] and one is a normal compressed archive [.bz2]
However, when I try to open the first file in the Gnome archive manager, the ".bz2" file loads instantly, while the "tar.bz2" takes a long time to be read.
Why though ?
Also, for the purpose of backup and data integrity, which is a superior format/container?
EDIT: I know the bz2 compressed disk image is 16Gb, but why is it listed as the compressed 12Gb in the archive reader, as opposed to the full 16Gb ?
EDIT2: Stranger still is that the tar.bz2 file is listed at the original, uncompressed size ...
