• none - (Default) Do not preserve attributes. This mode is supported on all file systems.
Important Usage Information:
• Xattr are not preserved for directories.
• If Aspera Sync is run by a regular user, only user-level attributes are preserved. If run as
superuser, all attributes are preserved.
--proxy proxy_url
Synchronize using the specified IBM Aspera Proxy address. The Proxy URL is specified with the
following syntax:
dnat[s]://proxy_username:proxy_password@proxy_ip_address[:port]
The default port for DNAT is 9091, and for DNATS is 9092. The Proxy password must be specified
or the synchronization fails to connect to the Proxy server.
-R rem_log_dir,--remote-logdir=rem_log_dir
Use the specified logging directory on the remote host. The directory is created if it does not already
exist. If <async_log_dir> is set in aspera.conf on the server, async initially logs to
rem_log_dir but is then redirected to the directory specified for <async_log_dir>.
Note: -R cannot be used if the transfer user is restricted to aspshell.
-r rdir, --remote-dir=rdir
Synchronize the specified directory on the remote host. rdir is [[user@]host:]path. If the target is the
remote directory, you can use--create-dir to create the remote directory if it does not already
exist.
CAUTION: If the source and target directories are both on the local host, do not
specify a target directory that is inside your source directory.
--remote-force-stat
Force the remote Aspera Sync to retrieve file information even if no changes were detected by
scanning or file system notifications (equivalent to the behavior of Aspera Sync versions 3.8.1 and
older). This option incurs a performance cost at the expense of immediately detecting file changes.
See also --local-force-stat.
--remote-fs-threads=number
Use up to the specified number of threads to do file system operations on the remote computer.
Default: 1. This option is particularly useful when the remote Sync directory is in cloud storage
or mounted storage (NFS) where file system operations are slow. To set multiple threads for file
system operations on the local computer, use --local-fs-threads.
--remote-mount-signature=signature file
Verify that the remote file system is mounted by the existence of this file. This option increases the
time required to synchronize deletes.
--remote-preserve-acls={native|metafile|none}
Like --preserve-acls but used when ACLs are stored in a different format on the remote
computer. Defaults to the value of --preserve-acls.
Note: Both --preserve-acls and --remote-preserve-acls must be specified in order
for the target side of the pull to apply the ACLs.
--remote-preserve-xattrs={native|metafile|none}
Like --preserve-xattrs but used attributes are stored in a different format on the remote
computer. Defaults to the value of --preserve-xattrs.
--remote-scan-interval=duration
Set the scanning interval of the remote computer. See also --scan-interval.
