Here is a short summary of the available options. Please refer to the detailed description below for a
complete description. Some options only have a long variant.
-r, --recursive
recurse into directories
-v, --verbose increase verbosity. This option increases the amount of information your are
given during the transfer
-l, --links copy symlinks as symlinks
-p, --perms preserve permissions. This option causes the receiving Rsync to set the
destination permissions to be the same as the source permissions.
-o, --owner preserve owner (super-user only). This option causes Rsync to set the owner of
the destination file to be the same as the source file
-g, --group preserve group. This option causes Rsync to set the group of the destination file
to be the same as the source file.
--ignore-existing Ignore files that already exist on the receiver. This tells Rsync to skip updating
files that already exist on the destination.
-b, --backup With this option, preexisting destination files are renamed as each file is
transferred or deleted. You can control where the backup file goes and what (if
any) suffix gets appended using the --backup-dir and --suffix options
--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. You can
additionally specify a backup suffix using the --suffix option (otherwise the files
backed up in the specified directory will keep their original filenames).
--suffix=SUFFIX This option allows you to override the default backup suffix used with the --
backup (-b) option. The default suffix is a ~ if no --backup-dir is specified,
otherwise it is an empty string.
-D, --devices preserve device files
--specials preserve special files
-t, --times preserve times
-S, --sparse handle sparse files efficiently
-z, --compress Compresses file data during the transfer. This option is useful in slow links.
-a, --archive This is equivalent to -rlptgoD. It is a quick way of saying you want recursion and
want to preserve almost everything (with -H being a notable omission).
-E, --executability This option causes Rsync to preserve the executability (or non-executability) of
regular files when --perms is not enabled.
-h, --human-
readable Output numbers in a human-readable format.
--stats Give some file-transfer stats.
--delete Delete files that don't exist on the sender.
--log-file-
format=FORMAT Output filenames using the specified format.
--log-file=FILE Output filenames using the specified file.
--bwlimit=KB/S Limit I/O bandwidth; KBytes per second.
-n, --dry-run This tells Rsync to not do any file transfer; instead it will just report the actions it
would have taken.
--timeout=SECS Sets the maximum I/O timeout in seconds. If no data is transferred for the
specified time then Rsync will exit. The default is 0, which means no timeout.
