 Why is recovery so important for businesses and why Exchanges may crash?

Companies often store critical client mailbox data on an Exchange server database. The Exchange database is a warehouse of critical mailbox information such as contacts, notes, calendar items and emails of thousands of users. One of the most serious issues companies can face is the corruption of the Microsoft Exchange 2013 database file leading to unavailability of important data for the client. The Microsoft Exchange 2013 database can become vulnerable to crashes due to unavoidable hardware issues, software malfunctions, system freezes, server or boot failures, accidental shutdowns or any unforeseen circumstances. Since the last thing a company wants is to endanger business goals such as data availability during disasters, the first step is to make efforts to recover the damaged file.

The importance of Backup and Log files

One of the simplest ways to recover a corrupted or crashed server is to recover the Exchange server database from a recent backup. But to recover it from a backup, Exchange transaction log files play an important role. Each Exchange transaction is first and foremost written to a log file present on the hard disk and then committed to the database on the server from the log files. Database administrators use the gap between the two processes to copy log files to other discs to serve as a backup in a time of crisis. Therefore, even if the main database files get corrupted, the log files remain available and safe and can be replayed to recover lost mailbox data.

Manual Methods for Exchange 2013 Database Recovery

There are two ways of manually recovering the Exchange server database through replaying log files i.e. the soft and hard recovery. The first step to recovery entails providing a folder path location as to where the Exchange database and log files need to be restored while also ensuring there is enough free space on the disk. Depending on whether the database file is in Clean Shutdown or Dirty Shutdown state using the Eseutil /mh command, perform the soft and hard recovery. Then one should proceed to create the recovery database in order to mount the database from the backup, followed by restoring the mailboxes using the Exchange PowerShell commands. In case the log files are missing or unavailable, the database will show errors. In this case, the database administrators need to start the repairing process using the Eseutil/p command. However, the command should only be used in conditions of extreme desperation, such as a case where the recovery of a database from a backup doesn’t work.

Limitations of Manual Methods

These Microsoft-powered built-in utilities are commonly used to fix and repair Exchange database issues. However, these tools proved a failure in cases of severe corruption and database mount failure. Also, if the log files are missing, unavailable or can’t be replayed using the manual methods, then manual methods are called as unsuccessful in recovery. To top it off, these repair utilities are command-line based and not GUI-based, which requires a lot of technical knowledge and learning. Unless the database administrator has hands-on knowledge about the commands, one wrong command can result in devastating outcomes for data loss. For example, using the manual tool may lead to inevitable data loss, if the Eseutil finds a corrupt page, a table with a broken link, or if the deletion of an internal page is required to improve the structure. This would require defragmentation using Eseutil /d and correct B-tree structuring to rebuild the entire database, which is basically a lot of extra effort, manpower and time.

Final words on the choice between Manual Methods and 3rd party tools
