Rsync Defaults for Archive Flag

Using rsync without the “archive flag” (-a).

What does -a default to? It is the archive mode.

-a, --archive; archive mode; equals -rlptgoD (no -H,-A,-X)


-r, --recursive; recurse into directories
-l, --links; copy symlinks as symlinks
-p, --perms; preserve permissions
-t, --times; preserve modification times
-g, --group; preserve group
-o, --owner; preserve owner (super-user only)
-D; same as --devices --specials
--devices; preserve device files (super-user only)
--specials; preserve special files

Aside, perhaps for disk-to-disk usage

-x, --one-file-system; don't cross filesystem boundaries
