I’m trying to use the ‘sync’ command to sync a local and remote directory,
but when I do so and there are a large number of files in the directories being
compared, it never seems to complete. When I run the command with the -v option,
it seems stuck at “INFO: Verifying attributes…” There are about 350 files
in the remote directory, and slightly more in the local directory. The files
are media files (movies), and so are somewhat big (~100 MB each). I’ve never
seen it finish (even after waiting upwards of 20 minutes) – is it reasonable
that it would take a very long time to do this, or is something else wrong?
If so, is there a workaround?
