Hi @H. Singleton,
Based on your query, here is my understanding: You would like to know why there is a limit of download the files within or till 30days.
I would like to credit @Andy David - MVP regarding the impacts of load on the service while storing or retrieving the logs. As mentioned, it provides detailed information for the last 30days which is lot of information.
Now I would like few more points regarding the 30 days logs. All the audit and sign in logs last mostly for 30days (depending on licenses). The lifecycle of the user as well depends on 30days. When a user soft deleted he gets permanently deleted in 30days which will also be dependent to access reviews when you review the lifecycle objects.
These are just examples that I would like to provide you but there are many other features which are defined with same 30days time period. Since access reviews works on many features and logs that is the reason it has been dependent with specific days.
Some of the examples how access review features work with 30days:
Enable reviewer decision helpers: No sign-in within 30 days is Enabled by default. When this is enabled, system recommendations based on users' access information over the last 30 days will be shown to the reviewers.
If reviewers don't respond:
Remove access: The system automatically marks members that haven't signed in for greater than 30 days for removal. The system recommends users that have signed in within the last 30 days to remain as active members.
Approve access: The system automatically marks members as approved allowing them to remain as active members. They remain active, even though the system's default recommendation is to remove the user's membership because they have not signed in for greater than 30 days.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
