Microsoft Exchange Server may sometimes report errors when an Exchange-aware backup is running. Not always, but database corruption is the most common reason for a backup failure. You can analyze the exact cause of the problem by the event ID and related error description logging in the application log of Exchange Server. If this comes out to be database corruption, you then need to implement
Exchange Server Recovery methods.
For example, consider the below event ID and backup failure error, which might occur post failure of a backup attempt.
Event ID: 217
Source: ESE
Type: Error
Category: Logging/Recovery
Description:
Error err_num During backup of a database location. The database will be unable to restore.
The symbolic name of the above error is 'BACKUP_ERROR_FOR_ONE_DATABASE'.
Cause
To know the root cause of the given problem, you should check the err_num in description section of the above event. Common reasons for backup failure are described underneath:...

Microsoft Exchange Server is a reliable and advanced solution to create a collaborative and messaging environment. It stores all the user mailboxes in Microsoft Exchange Server database (EDB file), which can be accessed using Microsoft Outlook Email client. You should regularly backup EDB file to prevent any sort of data loss situations, if database is damaged. However, under some circumstances, Exchange Server database can not be accessed after restoring from a backup. The database restores properly, but you encounter errors while trying to access it. This behavior leads to critical data loss and needs
Exchange Server recovery to be sorted out.
For instance, you may come across any of the following behaviors after restoring the Exchange Server database from current backup:

Microsoft Exchange Server is an exchange server that is server-side of the client-server product. It stores all the information of emails, contacts, calendar entries in an EDB (Exchange Information Store Database) file. In addition, you can access Exchange Server using Windows-based mobile devices as well. Sometimes, you are unable to mount the Exchange Server because of EDB file corruption. The reasons that lead to EDB corruption are human errors, database header corruption, virus infections, oversized EDB file. In such cases, you should try to find the cause of corruption and perform appropriate operations to repair corrupt EDB file. If you are unable to do this, then you should use a third-party
EDB recovery software to recover EDB file.

In Microsoft Exchange Server, you must replay the log file after restoring your EDB (Exchange Server database) from an online backup. This process is known as Hard Recovery. It helps you to recover your Exchange Server database in case of database corruption or database failure. However, in some situations, the Exchange Server hard recovery fails and the database remains in inaccessible and unusable state. At this point, you need to repair and restore the corrupt database using advanced
Exchange recovery tools.
As a practical example of this problem, the hard recovery of Exchange Server with Eseutil /cc may fail and you come across the below error message:
“Operation terminated with error -939523485 (Existing log file is not contiguous.) after 0.481 seconds.”
At the same time, you may see any of the following Events in the Application Event Log of Microsoft Exchange Server:

In Microsoft Exchange Server, you are required to to perform hard recovery after restoring your database from an online backup. Hard recovery is a log replay process, which is similar to the soft recovery, however there are a few critical differences. If you do not complete the hard recovery process after restoring the database from backup, the restore process is not successful. In some situations, the hard recovery process fails and your database remains inaccessible even after restoring from an online backup. This behavior causes severe data loss and requires
Exchange Recovery to be sorted out.
As a practical instance of this behavior, the hard recovery process may not complete successfully with eseutil /ff command after restoring Exchange Server database (EDB file) from online backup. Additionally, you receive underwritten error message:
"Operation terminated with error -939523485 (Existing log file is not contiguous.) after 0.481 seconds."...

Exchange Server is the server side application from Microsoft to create a collaborative messaging environment. It is made of various components, and Exchange Server Information Store is a significant one among them. All the database components work together to perform required operations and keep Exchange Server up. However, there are several factors that can damage the Exchange Server components and may make it unusable. This behavior renders your Exchange Server database (EDB file) inaccessible and cause severe data loss. To recover lost data at this point, you must go for
Exchange Recovery solutions, if a valid backup is not available.
When Exchange Server database corruption takes place, Exchange Server Information Store is the most commonly affected components. Microsoft Exchange Server Information Store comprise of the below four database files:
1.Priv1.edb
2.Pub1.edb
3.Priv1.stm
4.Pub1.stm

When you install Microsoft Exchange Server 2007, a set of tasks is run to install few services. One of these services is Microsoft Exchange Transport Service, which is a network service responsible for SMTP and transport stack. At times, you observe that the service fails to start. Among other reasons, one root cause of this problem is corruption of ESE ( Extensible Storage Engine) database. This occurs when the corrupted database exists on Edge Transport Server or Hub Transport Server and has been serving as Content Filtering database or message queue database. This clearly means corruption and calls for actions to apply
EDB Recovery solutions.
For more clarification of the issue, let's consider a problem when you attempt to start Microsoft Exchange Transport Service, but fail to do so. Further, on viewing the application log, you encounter the below event ID logging:

A storage group in Microsoft Exchange Server Information Store contains one or more mailbox stores, depending on the version of Exchange Server you use and requirements of the organization. Mailbox stores are the most critical components from data preservation perspectives as they comprise of system and user mailboxes. If corrupted, mailbox store causes serious problems in the working of an organization. A mailbox store is further comprised of two files, namely Priv1.edb and Priv1.stm. Corruption usually affects Priv1.edb file and occurs because of typical reasons like, database dirty shutdown, anti-virus software scan, virus infection, and network issues. When corrupted, EDB file on being accessed, prompts errors under a few event IDs, which can be read from application event log. Following is one such event IDs that generally occurs because of database corruption and requires
EDB Recovery solutions...

Is your Exchange Server database inaccessible due to corruption of the Information Store? Are you getting Jet Database Engine errors while restoring database from backup? Information Store is the most commonly affected Exchange Server component, when database corruption occurs. Corruption generally occurs in Priv.edb or Pub.edb, that are located in ExchSrvr\Mdbdata directory on server. EDB (Exchange Server Database) is an extension of Exchange Server database file. In case of corruption, the database becomes inconsistent and Exchange Server can not read data from it. It leads to significant data loss situations and needs
EDB Recovery, if you do not have an updated backup in place.
Microsoft Exchange Server indicates Information Store corruption with a number of symptoms, which include:
1. You can not start Microsoft Exchange Server Information Store Service.
2. The Information Store Service can not be stopped...

Microsoft Exchange Server is a well-known application that is used to create collaborative messaging environment. It is installed on server and can be accessed from client computer using Microsoft Outlook. Exchange Server 2003 and Exchange Server 2000 use MS IIS (Microsoft Internet Information Services) to provide Exchange-related services. All configuration settings of the IIS are stored in IIS metabase. The formation of metabase contains various settings of properties of different nodes. However, in some situations the metabase may get damaged and cause critical EDB (Exchange Database) corruption scenarios. To sort out this problem, you need to opt for
Exchange Server Recovery, in case of unavailability of backup.
Corruption of IIS metabase and Exchange Server database is a very serious concern. It can cause several Exchange Server vulnerabilities and make Exchange-related services unusable. In case of metabase corruption, you may encounter the below error message:...

In several Exchange database operations, like (but not limited to) backup process, the operating system is called to read database pages that have to be written on disk. During this operation, the checksum value placed in database page header is compared with that returned by READ operation. The backup operation fails if these values do not match. Such errors indicate corruption in database and need backup availability to restore lost data. But in cases when user finds it unfeasible to restore from backup (because it is corrupted or incomplete), a Microsoft
Exchange Recovery tool can help.
To depict the probable events, let's take a related scenario of an Exchange Server 2003 user. When he runs a backup utility to copy the Exchange database, the operation halts with an error that reads:
“Database was not found and could not be backed up. Please make sure database exists and is mounted.”...
