splunkconf‐backup cost optimisation with tag and frequency - splunk/splunkconf-backup GitHub Wiki
Introduction
Cost will vary depending on :
- AWS region
- your AWS discount
- backup frequency
- storage class (by default STD is used for hourly then IA for other backups)
- number of instances to backup
- role and content on each instance
Cost simulation
This cost simulation is done on a test environment with :
- one SH with ES app on it and multiple addons plus a few apps
- one DS
- one MC
- one CM (which also push ML librairies to idx layer)
- idx cluster
backup sizes in MB
| instance type | State backup in MB | etc targeted backup in MB | kvdump backup in MB |
|---|---|---|---|
| CM | 267 | 15.8 | 0.018 |
| MC | 1.3 | 44.3 | 0.020 |

backup frequency
backup frequency is the one from default terraform values
| instance type | nb hourly STD | nb daily IA | nb weekly IA | nb monthly IA |
|---|---|---|---|---|
| CM | 60 | 60 | 10 | 12 |
| MC | 60 | 60 | 10 | 12 |
| SH | 60 | 60 | 10 | 12 |
| DS | 60 | 60 | 10 | 12 |
This is 2880 STD PUT per month and 144 IA PUT per month
