IBM Aspera HST Admin Manual page 242

Verify that the local file system is mounted by the existence of this file. This option increases the
time required to synchronize deletes. See also --remote-mount-signature.
-m rate, --min-rate=rate
Attempt to transfer no slower than the specified minimum transfer rate. rate is an integer with units
of G/g, M/m, K/k, or bps. Default: 200 Kbps.
-N pair, --name=pair
Assign a name for the synchronization session. The value can contain only ASCII alphanumeric,
hyphen, and underscore characters. This value is stored in the session cookie and can be used in
IBM Aspera Console to identify the transfer session.
Note: -N must precede all session options.
-n action, --symbolic-links=action
Handle symbolic links with the specified method, as allowed by the server. For more information on
symbolic link handling, see
action can be:
copy - create or update the link at the destination (default). Not valid for Windows source or
destination.
skip - ignore the link altogether.
follow - treat the link as if it were the file or directory it points to, so that at the destination,
what was a link is now a copy of the file or directory. Functions as skip if source is Windows.
--no-preserve-root-attrs
Disable the preservation of attributes on the Aspera Sync root.
--no-scan
Never scan. Use this option in a continuous async session to synchronize only new files (files that
are added to the directory after the start of the async session) but not existing files. With --no-
scan, Aspera Sync relies entirely on file system notifications to detect changes. As a result, if a
directory is renamed after the async session starts, then the directory name is synchronized but
the contents are not (because Aspera Sync does not recognize that the files were "moved" to the
renamed directory). This option cannot be used with --scan-interval or one-time async
sessions.
-O port, --udp-port=port
Use the specified UDP port for FASP data transfer. Default: 33001.
-o policy, --overwrite=policy
Overwrite files according to the specified policy, which can be always, older, or conflict.
Use with -K push and pull. Default: always for -K push and pull; conflict for -K
bidi.
Note: When syncing with object storage, only file size (--checksum=none) can be used to
compare files. Thus, using --overwrite=always only overwrites files whose sizes have
changed. If the content of a local file is different from a file with the same name in object storage
but the files are the same size, the file in object storage is not overwritten. To overwrite files in this
case, use --overwrite=older.
--overwrite=older is only accurate if the user also specifies --preserve-time (preserve
timestamps).
To resolve conflict and error situations in a uni-directional sync, "touch" the problem files on
the source and run async with --overwrite=always. This clears all conflict and error
states as the problem files are synchronized.
-P port, --tcp-port=port
Use the specified TCP port for SSH. port must be a valid numeric IP port. Default: 22.
