One thing that can cause problems when creating an archive of disk
images is that you can run out of disk space when creating/updating
the archive. This is especially true when using the j or z options
so that tar compresses the archive. It has to have enough space to
uncompress the archive, and the new file, and compress it again.

You should also consider where tar is putting its temporary files.
It may not be on the same file system as the archive. I believe tar
honers the TMP shell variable.
