A bit frustrating. I could see no attributes updating, i.e.
you can replace_content, add_files, add_data, but nothing to say
change the mtime when updating the archive- an obvious task for incremental backups.
The compress didn't seem to work (i.e., no file size reduction
on using the 1 -> compress values- I install all dependent modules).
It could not produce gzip format that my redhat fileroller viewer could
