Circular Logging (Circular Logging) in Exchange Server refers to a special type of logging that is primarily used to control the growth of transaction log files. By default, Exchange Server generates a series of transaction log files to keep track of every modification made to the database so that these changes can be replayed when the database is restored, achieving data consistency and integrity.
Now, let's explore the process of how to configure circular logging of Exchange databases with two methods.
How to use EAC to configure circular logging exchange?
The Exchange Admin Center (EAC) is a web-based management interface provided by Microsoft Exchange Server to manage and configure various features and services of Exchange Server. Through the EAC, administrators can easily enable or disable ring logging.
To enable exchange database circular logging, following these steps:
1. In the EAC, go to Servers > databases
2. Select the mailbox database > click it
3. Check or uncheck the Enable circular logging checkbox > click Save
How to use PowerShell to configure exchange database circular logging？
PowerShell provides a scripted approach to managing Exchange Server, allowing administrators to write scripts to automate tasks. This is especially useful for large deployments as it saves a lot of time in manual operations and reduces the risk of human error. By using PowerShell, administrators can easily enable or disable ring logging.
This example enables circular logging for database DB1.
Set-MailboxDatabase DB1 -CircularLoggingEnabled $True
This example disables exchange database circular logging DB1.
Set-MailboxDatabase DB1 -CircularLoggingEnabled $False

Circular logging FAQs
Q1: What are the advantages and disadvantages of enabling circular logging?
Pros:
Saves disk space: reduces storage requirements, especially in environments with high log generation.
Reduces administrative work: reduces the need for administrators to periodically clean up log files.
Cons：
Restricted recoverability: because old log files are overwritten, it is not possible to use full log files for point-in-time recovery, only to the last full backup.
Cannot perform incremental backups: cyclic logging does not support incremental backups, all backups are full backups.
Q2: Is it possible to use circular logging in all environments?
A2: Cyclic logging exchange is suitable for small or test environments and is not recommended for use in production environments, especially if a strict data recovery policy is required.
