When tar is given a folder name, it will create a recursive tarball of that folder (and all files/folders inside it), then it'll again keep adding the individual files that it is given by find. So, the final tarball size will bloat up with a lot of duplicate copies of stuff. Though it won't create much issues while unpacking even if u do this, because files will get overwritten again and again and you'll finally get a sane output. 2. About duplicate names in diff directories, they will get backed up because find doesn't just list the names, it lists the complete path. Vince,

Can you explain regarding this point:
“only filenames are listed … because tar creates a lot of issues when presented with directory names”

What about duplicate names in different directories do they not get backed-up?
