subject: Online Sql Server Database Recovery - To Shut The Door Of Damaged Mdf Files [print this page] SQL Servers store data and after storing data in SQL, users are not required to know where data exist in SQL Server because SQL users use databases. However, administrators should know all about SQL databases location.
MDF Group Files: SQL Server by default creates database.mdf files where whole data is stored. The log file of MDF files is database_log.mdf, SQL Server stores data in three files types and one of them is MDF file. Suppose you are running a large organization then it is obvious SQL management can be cumbersome. This is why SQL provides facility to create group related files into file groups. File groups will reduce your burden of management.
Causes of Corruption in SQL:
Power outage or power surges cause to unsystematic shutdown of system lead to loss of MDF files
Failure of physical disk can be one of the reasons to cause corruption to MDF files. Disks have limited life so if you are using array types including RAID 1, striping with parity Raid 1, lessen your exposure
Suppose virus-scanning utility is running on Server and you are recovering, then might be virus scan locks database files, which might bring serious loss to data stored in MDF files
Inadvertent deletion of data in MDF files is one the main cause of losing data stored in MDF files
Internal program errors
Trojan infection
Because of cache, .mdf files are damaged
Adopt a Backup Strategy: If you always keep backup copy with you there are least chances of investing in Online SQL Server Database Recovery software. SQL Server is kept for large databases in organizations, so for security purpose keep backup data with you.
Before taking backup of the data, think of following queries:
How much data can be lost and how important it is for you not to lose a single data
How often you should take back up of the data, regularly or after a week
Do you need to take backup every time or after once in a week
How much data you think to be backed up and for how long you need to keep backup copies with you
Once MDF file corruption confirmed, take help from external applications because they provide best possible consequences. Corruption to SQL files results in inaccessibility of data and error messages. If backup data is available to you then restore corrupted data in case on unavailability of backup data then another route is professional help.
