Data log files are not backed up by the DSView 3 software backup utility.
When a data log file is created, a companion signature file with the same name is created, but with
a .sig file name extension. This file is digitally signed using the DSView 3 software private key.
When a user wants to display the content of a data log file, the DSView 3 software will first verify
the digital signature to ensure the file has not been altered.

You may also export the DSView 3 system X.509 certificate and use its public key to validate the
signature of files, using external tools. See System certificate and SSH key on page 46.

Data log licenses
A data log license is used for each enabled data log port connection. A direct SSH/Telnet session to
an appliance will not require or use a data log license for the DSView 3 software to capture data
logs for that appliance session. Only sessions related to appliance ports require a data log license.

A data log license is used when data logging is enabled on a port connection. When data logging is
disabled on a port connection, that license is freed and returned to the available pool.

The DSView 3 software ships with 32 available data log licenses - that is, 32 data logging sessions
may be enabled on appliance connections that support data logging. An add-on license key may be
obtained to support a certain number of additional data logging sessions or an unlimited number of
data logging sessions (site license). See Licenses on page 54 for more information.
