Data Recovery and Exchange Corruption

Data recovery

It’s advisable to make a backup copy of all .log, .stm and .edb files as you try to repair or attach a damaged database. It applies to all software utilities ranging from third party developers to Microsoft. You might end up deleting some objects in the database even if they were initially salvageable hence causing further losses.

You should also not try to fragment any source of data if the mail server was not brought offline in a proper manner. Such an action may bring inconsistencies in the data store which may lead to corruption if you attempt to defrag. You should not send the damaged database to any recovery agency or open a technical support case with Microsoft without creating a backup copy of your email data storage. Make sure you back up your data storage more often. You could have a full backup twice a week or incremental backup on a daily basis.

Data Recovery and SQL Corruption

The first point to note in this case is that you should not make a database backup on the same drive. It will not make any sense if the drive gets corrupted. Secondly, don’t use the array or disk if the database corruption came as a result of hard disk failure, bad sectors, RAID collapse or check disk utility.

Make sure you make a copy of existing database files before you restore the database. Sometimes the backup may be corrupted or outdated, and the restore process may end up overwriting the actual data. Make a copy of the log files and database to an alternative physical drive before carrying out anything.

Data Recovery and Raid Collapse

You should not pick any form of advice from an OEM support staff unless they are the ones who configures your system and there are no changes since then. You must understand the drives that have failed before you attempt to rebuild the array. It’s also critical to know when these drives failed and the reasons behind the failure.  

RAID recalculation that incorporates old data from any drive that fell offline first may end up corrupting all your data. This occurrence is visible in almost 30% of all raid recoveries that take place on a daily basis. Do not attempt anything unless you are familiar with the controller routines, configurations, and the hard drives. You should also use the right file recovery software lest you mess up the system further.

In case you are not sure of what you need to do, it’s advisable to call a technician to assist with the process. Some users believe that free data recovery software is easy to use. However, you must understand some technical aspects of these systems before you embark on the task. You don’t want to lose more data in your attempt to recover what you have lost.
