Data corruption is the damage of info due to various hardware or software problems. After a file is damaged, it will no longer function properly, so an app will not start or shall give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, that makes it a significant problem for website hosting servers as fails are very likely to occur on larger hard drives where significant volumes of info are located. When a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and will be duplicated on all drives, making the harm permanent. A huge number of the file systems that operate on web servers these days often are not able to find corrupted files in real time or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Web Hosting

We have dealt with the matter of silent data corruption on all our web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one on the market which checks all files right away by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and continually synchronized between them for redundancy. ZFS constantly compares the checksum of all files and in the event that any file is detected as damaged, it's replaced promptly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other SSDs. ZFS needs a lot of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we take advantage of multiple very powerful servers working together. In case you host your Internet sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't have to deal with any silent data corruption issues whatsoever in case you get one of our semi-dedicated server packages as the ZFS file system that we employ on our cloud hosting platform uses checksums to make sure that all of the files are undamaged all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Due to the fact that we store all content on multiple drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the bad copy to be synchronized on the other drives. ZFS is the sole file system you can get which uses checksums, which makes it far superior to other file systems which cannot detect silent data corruption and duplicate bad files across drives.
