Server-Side Symbolic Link Handling

Aspera handles symbolic links in IBM Aspera Sync based on settings configured in the aspera.conf file, found in the following location:

/opt/aspera/etc/aspera.conf

Configuration Options

The following configuration options are set in the <file_system> section of the aspera.conf file:
  <file_system>
    <symbolic_links>comma-separated_options</symbolic_links>
  </file_system>
Note: If no option is specified, the configuration defaults to create, follow.
Option Description Client Behavior Server Behavior
create Create symbolic links with arbitrary targets. This is the default. Disallowed if not configured.

Note: Servers running on a Windows platform will always reject such a request, regardless of the option configured.

Symbolic links are always copied to the server if the client requests.
follow Follow symbolic links with targets inside docroot. If at any point the path goes outside the docroot, Aspera Sync will not complete the transfer. This is option set by default. Symbolic links are always copied to the server if the client requests.

Note: If the docroot is a symbolic link and is specified as the source or destination: As the receiver, follow the target widely (no docroot constraint) and unconditionally, regardless of the symbolic link actions that are configured/requested.

follow_wide Follow symbolic links with arbitrary targets, even if the targets are outside the docroot.   Disallowed if not configured, except for Windows servers. Follow symbolic links anywhere without docroot constraint.

Note: If the docroot is a symbolic link and is specified as the source or destination: As sender, follow the target unconditionally, regardless of the symbolic link actions that are configured/requested.

none Take no action with symbolic links. Take no action with symbolic links. Take no action with symbolic links.
