KEEP_LOGS_DAYS value

Hi,

In master server host properties ----> Clean-up ----> Keep logs value is set for 60 days.

In registry -        HKEY_LOCAL_MACHINE ---> SOFTWARES ---> VERITAS ---> NETBACKUP --->  CURRENTVERSION ---> CONFIG ---> KEEP_LOGS_DAYS value is showing Decimal and Hexadecimal value as 3.

Are these values for different things or what?

By default logs are kept for 28 days, right? Are all three pointing at the the same logs?
