-fast
Recommended when using GridFTP servers. Use MODE E for
all data transfers, including reusing data channels between list and transfer

-rst-retries RETRIES
The maximum number of times to retry the operation before
giving up on the transfer. Use 0 for infinite. Default is 5.
-rst-interval SECONDS
The interval in seconds to wait after a failure before
retrying the transfer. Use 0 for an exponential backoff. Default is 0.
-rst-timeout SECONDS
Maximum time after a failure to keep retrying. Use 0 for
no timeout. Default is 0.

How long before cancelling/restarting a transfer with no
data movement. Set to 0 to disable. Default is 600 seconds.
-df FILENAME, -dumpfile FILENAME
Path to a file where untransferred URLs will be saved for
later restarting. Resulting file is the same format as the -f input file. If
file exists, it will be read and all other URL input will be ignored.
-do FILENAME, -dump-only FILENAME
Perform no write operations on the destination. Instead,
all files that would be transferred are enumerated and dumped to the specified
file. Resulting file is the same format as the -f input file. Note: if you
intend to use this file as input for a future transfer, the -create-dest
option will be required if any destination directories do not already
exist.
-rp, -relative-paths
The path portion of ftp URLs will be interpreted as
relative to the user’s starting directory on the server. By default,
all paths are root-relative. When this flag is set, the path portion of the

-af FILENAME, -alias-file FILENAME
File with mapping of logical host aliases to lists of
physical hosts. When used with multiple concurrent connections, each
connection uses the next host in the list. Each line should either be an
alias, noted with the @ symbol, or a hostname[:port]. Currently, only the
aliases @source and @destination are valid, and they are used for every source
or destination URL.
-sync
Only transfer files where the destination does not exist
or differs from the source. -sync-level controls how to determine if files
differ.
-sync-level number
Criteria for determining if files differ when performing
a sync transfer. The default sync level is 2. The available levels are:
•Level 0 will only transfer if the destination
does not exist.
•Level 1 will transfer if the size of the
destination does not match the size of the source.
•Level 2 will transfer if the time stamp of the
destination is older than the time stamp of the source.
•Level 3 will perform a checksum of the source and
destination and transfer if the checksums do not match. The default algorithm
used for this checksum is MD5, but other algorithms can be specified with the
-algo parameter.
-checksum-alg CHECKSUM-ALGORITHM
Set the algorithm type to use for all checksum operations
during the transfer.
-verify-checksum
Perform a checksum on the source and destination after
each file transfer and compare the two. If they do not match, fail the
transfer. The default algorithm used for this checksum is MD5, but other
algorithms can be specified with the -checksum-alg parameter.
