Exchange Server: Transaction Log Management
Exchange Server does not write data directly to the EDB database. Instead, it first records all operations in a series of transaction logs, which are later consolidated. If the database becomes corrupted, these logs can be used to restore the server in combination with the most recent backup.
However, if these logs are not properly managed, they can grow uncontrollably, filling up storage space and significantly degrading server performance.
Best practices for managing Exchange environments:
- Use separate physical disks for transaction logs and the EDB database.
- Do not enable circular logging, as it limits the ability to fully recover data in the event of failures.
Exchange generates a fixed-size log file for every transaction and applies the changes to the database afterward. Logs are only consolidated and deleted when the database is backed up.
This ensures you can recover even the most recent email in case of a disk failure by restoring the backup and replaying any uncommitted logs.
