Caching technique in which the changes to the data in cache are not copied to cache source unless it is highly required to do so is known as Write Back Cache . This technique is implemented on the hard drives to improve the write performance. It is very essential in fixing slow performance issues because of slower RPM and seek-time .
This technique, the hard drive could signal the successful completion of the writing process more rapidly than if this had to wait until data was entirely transferred to the disk media. Write back caching is available with several top microprocessors including Intel.
Though, write back cache is a very useful technique to improve write performance, but in some cases, like hardware failure and power failure, the write back cache memory does not get flushed out to the actual drive. It may cause corruption of the data.
The completed writing operation creates several problems for journaled file systems, generally because they bank heavily on knowing whether the write operation to the drive has finished or still unfinished. Journaled file system requires knowing that the log entry has made to the disk before it allows the metadata to be written on the drive.
When metadata has written to the drive, this transaction could effectively be deleted from log file and free up log space. Thus, if the write operations fails to make it to physical drive, the ordering is desecrated and the metadata and log could be lost, which results into the file system damage.
File systems are the most important data structure of a Linux system. It is extremely important to store and organize the data files and make them easily accessible. The operating system never directly interact with the file physically. What it do is that It just takes the reference from file system table and locates to the particular file .
In case of file system corruption, the operating system could not find the reference of particular file and thus fails to access it and this results in lot of hardship . This whole scenario will resultant into failing yo access of your precious data and finally the loss of data.
The data loss will definitely affect your business with decreased revenue and market reputation, Repairing this may cost a lot of time and money. In such disastrous situations, the only thing you should think of is data recovery Linux software .
Data recovery Linux is the technique of retrieving your important data from failed hard drive. It is best possible through Linux recovery software. These software are capable in handling all of the logical data loss situations including file system corruption.
