Sharing over Network If there is a need to access a single TrueCrypt volume simultaneously from multiple operating
systems, there are two options:
1. A TrueCrypt volume is mounted only on a single computer (for example, on a server) and
only the content of the mounted TrueCrypt volume (i.e., the file system within the TrueCrypt
volume) is shared over a network. Users on other computers or systems will not mount the
volume (it is already mounted on the server).
Advantages : All users can write data to the TrueCrypt volume. The shared volume may be
both file-hosted and partition/device-hosted.
Disadvantage : Data sent over the network will not be encrypted. However, it is still
possible to encrypt them using e.g. SSL, TLS, VPN, or other technologies.
Remarks : Note that, when you restart the system, the network share will be automatically
restored only if the volume is a system favorite volume or an encrypted system
partition/drive (for information on how to configure a volume as a system favorite volume,
see the chapter
System Favorite Volumes ).
2. A dismounted TrueCrypt file container is stored on a single computer (for example, on a
server). This encrypted file is shared over a network. Users on other computers or systems
will locally mount the shared file. Thus, the volume will be mounted simultaneously under
multiple operating systems.
Advantage : Data sent over the network will be encrypted (however, it is still recommended
to encrypt them using e.g. SSL, TLS, VPN, or other appropriate technologies to make traffic
analysis more difficult and to preserve the integrity of the data).
Disadvantages : The shared volume may be only file-hosted (not partition/device-hosted).
The volume must be mounted in read-only mode under each of the systems (see the
section
Mount Options for information on how to mount a volume in read-only mode). Note
that this requirement applies to unencrypted volumes too. One of the reasons is, for
example, the fact that data read from a conventional file system under one OS while the file
system is being modified by another OS might be inconsistent (which could result in data
corruption).
