Database Availability Groups (DAGs) serve as a safeguard by maintaining redundant copies of an Exchange database to ensure seamless recovery in the event of a failure. These redundant copies, while residing on distinct servers, are meticulously structured to mirror the path of the original database. For instance, if the primary database’s path is “Documents\database\mailbox1.edb,” the copy database on its respective server must adhere to the identical path, preserving “Documents\database\mailbox1.edb” for continuity.
Once a database copy is generated, continuous replication is automatically initiated between the original and the copy database. Exchange assigns a unique automatic identity to these database copies following the format <database>\<host server name>. This built-in feature serves as a safeguard against various potential issues, such as sudden deletion, data corruption, mishandling, and more, ensuring the overall stability and reliability of the database.
There are some prerequisites necessary for the process. See the following points –
To create a new path to the database copy, you can take the assistance of Exchange Management Shell only as there is no option in Exchange Admin Center (EAC) which you can use to complete the job. Here is the step-by-step process which you need to follow:
After you remove all the database copies, protect the database and transaction log files which will help you to reseed the database copies after adding them again (refer to Step 6 and Step 7).
Once the entire process is finalized, the copied database will reside in a distinct location from the original one. However, it becomes evident that this is a time-consuming endeavor, particularly when dealing with a substantial number of database copies or when the database size is extensive. Any single error or misstep in this process could potentially lead to corruption in the primary database.
In certain instances, the Exchange database can become entirely inaccessible, rendering traditional methods like relocating the database or altering its file paths ineffective in resolving corruption issues. In such cases, it is advisable to opt for a specialized professional tool that guarantees both security and error-free performance.
Introducing Exchange Server recovery software, a versatile solution designed to effectively address Exchange database file corruption issues. This software not only facilitates recovery but also serves as a seamless migration tool, effortlessly accessing the database from its current location and securely transferring it to a new Exchange Server. In the aftermath of database corruption, employing this software is a prudent choice, ensuring the retrieval of critical data and its safe relocation to a different Exchange Server. Eliminating the need for complex configuration adjustments or prerequisites, this software streamlines the recovery process, allowing you to swiftly Repair corrupt Exchange database with ease.
