Cisco ISE Monitoring node backup size

[NXO1Mikelees_2]

Hello All,

We have a HA pair of ISE servers that have scheduled backups configured for the Admin persona (currently full weekly backup) and monitoring which is full weekly but with the addtional incremental daily backups. I've not seen any issue with the full weekly backup of the admin node however the monitor one provides unusual results in terms of file size between weekly and incremental backups.

Given the fact that we are currently piloting this with very little radius activity i'm curious as to how the daily backups can be bigger in filesize than the weekly?

The ISE is a ISE-3315-K9 running 1.1.3.124 and below are some examples

-rw-r--r-- 1 tsmbackup tsmbackup 502960384 Apr 21 07:08 mntincr_1_<removed>.tar.gpg (Incremental backup)

-rw-r--r-- 1 tsmbackup tsmbackup 459348307 Apr 21 01:04 mntdbfull_<removed>.tar.gpg (Full backup)

Thanks in advance for any suggestions.

Hi,

This could possibly due to ‘Data Purging’. When a purge operation triggers, if the actual used database disk space is greater than the configured threshold, the purge operation removes all data from the Monitoring database tables prior to the data retention window.
