<p>As the name infers, <i>offline data processing</i> can only be accomplished
when the data is in consistent state (the operating system and all the
applications are completely shut down). Actually it is the most preferable
way of image creation or data cloning, since software can obtain an exclusive
right to process data that guaranties high level of operating efficiency.
However, the <i>offline data processing</i> is absolutely out of question
when dealing with 24/7 production environments.</p>
<p> </p>
<p>In contrast, <i>online data processing</i> enables to create a consistent
snapshot even as the data is currently modified. It is particularly useful
for systems with high availability requirements, but it wonÆt be accomplished
until all active transactions are complete. The point is to provide a
coherent state of all open files and databases involved in a process,
taking into account that applications may still keep writing to disks.
As a result an online data processing cannot boast high operating speed.</p>

<p>Our program supports both offline and online methods of data processing.
As far as online method is concerned it offers its own hot processing
algorithm.</p>
