-r, --recursive recurse into directories
-R, --relative use relative path names
-b, --backup make backups (default ~ suffix)
+ --backup-dir=DIR put backups in the specified directory
--suffix=SUFFIX override backup suffix
-u, --update update only (don't overwrite newer files)
-l, --links preserve soft links
which already exist and have the same checksum and size on the
receiver are skipped. This option can be quite slow.
-dit(bf(-a, --archive)) This is equivalent to -rlptg. It is a quick way
+dit(bf(-a, --archive)) This is equivalent to -rlptgoD. It is a quick way
of saying you want recursion and want to preserve everything.
-Note: if the user launching rsync is root then the -o (preserve
-uid) and -D (preserve devices) options are also implied.
-
dit(bf(-r, --recursive)) This tells rsync to copy directories
recursively. If you don't specify this then rsync won't copy
directories at all.
renamed with a ~ extension as each file is transferred. You can
control the backup suffix using the --suffix option.
+dit(bf(--backup-dir=DIR)) In combination with the --backup option, this
+tells rsync to store all backups in the specified directory. This is
+very useful for incremental backups.
+
dit(bf(--suffix=SUFFIX)) This option allows you to override the default
backup suffix used with the -b option. The default is a ~.
