To help protecting your valuable data effectively, you should have at least two
copies around in case one of thm gets corrupted. This sub-command
does just that, and copies the data to one or more destinations while it is being sealed.
[arguments ...] specify the source file(s) or directories, as well as the destination(s), for example
godi sealed-copy s/ /Volumes/a
godi sealed-copy s1/ s2/ -- /Volumes/a /Volumes/b`
)
