How can I create a multipart tar file in Linux?
You can use the
split command to split an archive in to multiple files. For example, if I wanted my archive stored in 1 MByte files:
tar -cvf - <stuff to put in archive> | split --bytes=1m --suffix-length=4 --numeric-suffix - myarchive.tar.
And when I want to recombine and untar:
cat myarchive.tar.* | tar xvf -
GNU Tar natively supports multiple volumes. There are many options, the one I found neat was
tar --create --multi-volume --file=/tmp/file1.tar --file=/tmp/file2.tar files_to_archive
size can be specified via -L (tape-length)
It does not support compression in this manner however, so you would have to seperately do that. "tar: Cannot use multi-volume compressed archives"
