Exchange Database Recovery prevents data loss due to mortiferous Exchange Server Errors

Power failures are ineluctable both for a novel and connoisseur Exchange Server user. Like a bolt from the blue, abrupt power failures, also termed as dirty shutdown affect the Information Store causing exchange database corruption. Abnormal termination causes the Information Store to crash and is one of the key factors responsible for Exchange database (EDB file) corruption.

Information Store Service is the pivotal element of Microsoft Exchange Server whose damage or corruption eliminates the entire accessibility of the user mailbox data stored on the server. Though this fact is indubitable that emails hold inestimable value for its owner but when the Exchange Infomation Store is affected rendering the user mailbox data inaccessible, a user also looses his contacts, calendars, tasks, journals, notes, schedules and appointments which can drastically play havoc in the life of a corporate guy.

But, for every problem there exists a solution as well. A lucid solution is to restore the Exchange Server database using an updated backup. Nonetheless, a backup may not be available in certain cases, or while trying to restore the database, using the backup file, certain error messages might forestall the process.

If any of the above scenario alludes you, then the perfect solution is third party Exchange Database Recovery tool.

Repairing of Exchange Server is the best option for corrupt Exchange Server

Behind corruption of MS-Exchange Server, faulty hardware is one of the major factors. Corruption in Exchange Server occurs shortly. In order to get rid of this issue, soft recovery can be used. Soft recovery is an automatic replay process of transaction log files that take place when a database is mounted again after an unexpected stop. Soft recovery employs the checkpoint file to check which transaction log file to start with it when transactions are replayed into databases sequentially. This is how; process of soft recovery helps you to make the databases up to date with all recorded transactions.

Discussed below is an event ID that is observed in the log file at a time of performing soft recovery. That, event ID appears to be like this:

“Product Name: Exchange

Product Version: 14.0 (Exchange 2010)

Event ID: 465

Event Source: ESE

Category: KHI

Alert Type: Error

Rule Path: Microsoft Exchange Server/Exchange 2010/Common Components/Extensible Storage Engine

Rule Name: Corruption was detected during soft recovery in the log file. The log file is damaged and is unusable. This may be caused by faulty hardware.”

Same error message disturbs every time while performing soft recovery. Recovery cannot be carried out smoothly.

Cause:

Reason for the occurrence of above error message is the detection of corruption in the log file while carrying out soft recovery.

Solution:

For solving the above erroneous situation, follow one or more of the below stated measures:

1) Try to perform restoration of the log file from a backup copy, perform the same if the log file defined is the current log file in use.

2) Make use of the Exchange Server database tool also known as Eseutil.exe with the /R and /A switches to recoup a database through missing log files.

However, if no proper results get found, then a third party Exchange Server Repair tool is a best solution. Several tools are easily available on Internet that is enough capable to recover Exchange Server objects, such as contacts, attachments, appointments, journal, tasks, events, etc. 

It is advised to be extra careful while doing selection of a third party tool. Same is advised because now days, a lot of third party tools are available that make fake commitments for their promotion. These tools prove harmful rather than beneficial. Stellar Phoenix Exchange Server Recovery is one of the reliable tools on which you can trust blindly.

And, when an attempt was made to mount the public folder, an error message written as below appeared on the screen:

“The database files in this store are corrupted”

Reason: The primary cause, which is responsible for the occurrence of above error message is the corruption of the Exchange Server database. Corruption occurs because of unexpected system shutdown, operating system failure, human error, application malfunction etc.

How to solve ? : In order to solve the above problem you need to apply soft repair method first. Follow the following steps to perform the soft repair process:

1) Run the following commands to check the consistency of database:
   eseutil /mh ..\mdbdata\priv.edb > mypriv.txt
   eseutil /mh ..\mdbdatapub.edb > mypub.txt

2) If any of the databases are found to be inconsistent, use the following commands to carry out the soft repair solution:

eseutil /r /ispriv
eseutil /r /ispub

3) Now use the steps listed in the MS KB article:
"How to recover from information store corruption"

How to Solve Exchange database Error -327

Exchange Database corruption is a common and major problem of Microsoft Exchange Server. There are many issues which lead to corruption in Exchange database like, database dirty shutdown, human error, hardware issues, virus infection, EDB file header corruption and network issues. In case of EDB file corruption, you are unable to mount the Exchange Server. In such situation, you should try to search the main cause of corruption and perform appropriate action to repair corrupt database.

When a Exchange Server database is corrupt or damaged, you should use your backup (if backup is available) to restore such corrupted database or run ESEUTIL utility to repair it. eseutil is a command line utility and located in the C:\Program Files\Exchsrvr\Bin folder.

Now suppose you run the ESEUTIL /D utility to defragment your Exchange database, the process fails and you might find the following error message in Application Event Log file:

“Operation terminated with error -327 (JET_errBadPageLink, Database corrupted) after seconds”.

At this moment, you might also notice that you are unable to perform any normal operation on the database and your Server being unresponsive.

Cause

The JET_errBadPageLink error generally indicates the logical corruption in database. This error might be the consequence of incorrect internal database structure.

Solution

In order to get rid of this error, you should use these methods:

* If you have the complete backup, restore your infeasible database.

* Transfer users' mailboxes to a healthy Exchange Server through 'Move Mailbox' features in Administrator tool.

* Execute ESEUTIL /P against the damaged database and check database for consistency by using the ESEUTIL /K command.

In case, the above method does not work well and problem still persists, it is suggested to use a third party Exchange database repair tool to efficiently handle the situation.

How to recover mailbox store database through Microsoft Exchange recovery tool

Logical corruption of Exchange Server database makes the saved data of Exchange Server totally inaccessible. Exchange Server objects contain data of contacts, e-mail messages, attachments, appointments, journal, tasks, events, and similar more. Exchange Server database gets corrupt or damaged because of faulty hardware, sudden system shutdown, and loss of power supply. In such data loss situation, backup helps you to restore data. If backup is unavailable or falls short to recover the database, then in such situations a third party Exchange Server Recovery tools can be used.

For further clarification of above issue. Let us consider a practical scenario. Suppose, you make a try to mount a mailbox store in a MS-Exchange 2000 server, but fails to mount it. In addition to this, you receive an error message that is:

''The database files in this storage are inconsistent
Id no: c1041739''

In addition to this, whenever you try to mount the database the following events are viewed in the application event log:

“Event Type: Error

The read operation will fail with error %7. If this condition persists then please restore the logfile from a previous backup.”

Cause:
Above error message is caused because of inconsistent state of the mailbox store database and public store database.

Solution:
For solving above error message, and to access data of the mailbox store database. You have to follow the below steps:

Confirm the database state by below steps:
1.Open command prompt.
2.Transfer to the Drive:\Program Files\Exchsrvr\Bin folder. This location is the default location for installation of Exchange 2000 server program files.
3.Enter the following command:
“eseutil /mh "drive:\program files\exchsrvr\mdbdata\database_name.edb"
4. Check the output to verify the database state. If the database is not in a consistent state, then you
will receive the below text in the Output:
State: Dirty Shutdown

If the database is in inconsistent state, then you can repair the database by following steps:

• Use a command prompt.
• Transfer the Drive:\Program Files\Exchsrvr\Bin folder.
• Enter the following command:
• eseutil /p "drive:\program files\exchsrvr\mdbdata\database_file_name.edb"
• Defragment and rebuild the database so that the database can be used in a production environment. To do the same, you have to enter the below command:
• eseutil /d /t:x "drive:\program files\exchsrvr\mdbdata\database_file_name.edb
• Check the database status is consistent or not by typing the following command, and can check the output:
• eseutil /mh "drive:\program files\exchsrvr\mdbdata\database_file_name.edb"

If the database is consistent, then the below text will appear in the output

• State: Clean Shutdown
• To repair the Exchange Server database, you have to execute Isinteg.exe utility. For doing the same, you have to enter the following command:
• Isinteg –s exchange_server_name –fix –test alltests
• Perform the steps 3 to 6 again for each database.
• Mount the databases.
• After the databases are mounted, perform storage group online backup.

If still the backup remains in an inconsistent state, then it is better to go for a third party Exchange Recovery tools. Several third party tools are available in the market that performs Microsoft Exchange recovery instantly. These tools have read-only and are non-destructive conduct.
