Device Server Requirements

Nightly Backup

Nightly backup will maintain 7 copies of the GUI Server database if the default installation
option is selected. The disk space requirement should be 7 * (device configuration
database size calculated above).
Storage capacity requirements are determined by the following equation:
(Retention period in days * Events per day * 200 bytes)/ 1,000,000,000 = storage size in
GB.
Log events average around 200 bytes each. Table 30 on page 206 lists some examples
for a Device Server managing just firewall/VPN devices based on a retention period of
30 days:

Table 31 on page 206 lists some examples for a Device Server managing just IDP
stand-alone devices running profiler based on a retention period of 30 days:

Traffic logs make up about 2/3 of all logs. Turning off traffic logs can result in a large
savings in storage space.
In NSM, logs are stored in
