The process of files getting damaged because of some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face because the larger a hard drive is and the more data is placed on it, the much more likely it is for data to get corrupted. There're different fail-safes, but often the information is corrupted silently, so neither the file system, nor the administrators notice a thing. Because of this, a bad file will be treated as a good one and if the hard disk drive is a part of a RAID, that file will be copied on all other drives. In principle, this is for redundancy, but in reality the damage will be even worse. Once a given file gets damaged, it will be partially or entirely unreadable, which means that a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your site content. Although the most widespread server file systems include various checks, they often fail to discover some problem early enough or require a long time period to be able to check all the files and the hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Web Hosting

We have dealt with the issue of silent data corruption on all our shared web hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems because it is the only one in existence that checks all files right away by using a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and regularly synced between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as corrupted, it is replaced quickly 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 requires plenty of physical memory to perform the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple powerful servers working together. If you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption since all of our storage servers work with the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of each file. When you upload content to your account, it will be stored on a couple of redundant drives being employed in a RAID i.e. the files shall be the same across all disk drives. All copies of a particular file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, and if it detects a mismatch, which would indicate that one of the copies is corrupted, it'll replace that file with a good copy from one of the other disks. Even if there is a sudden power loss, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to return online. ZFS is the file system which can truly protect your content from silent data corruption.
