The process of files being damaged as a consequence of some hardware or software failure is called data corruption and this is one of the main problems that web hosting companies face because the larger a hard disk is and the more info is stored on it, the more likely it is for data to get corrupted. You can find different fail-safes, still often the data is damaged silently, so neither the particular file system, nor the admins see anything. As a result, a bad file will be treated as a good one and if the HDD is a part of a RAID, that file will be copied on all other drives. In principle, this is done for redundancy, but in practice the damage will be worse. When a file gets corrupted, it will be partly or entirely unreadable, which means that a text file will not be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most widespread server file systems include various checks, they quite often fail to find some problem early enough or require a vast time period in order to check all the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the info uploaded in every single cloud hosting account that is made on our cloud platform since we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption through a unique checksum for every single file. We shall store your info on a large number of NVMe drives that operate in a RAID, so the very same files will be available on several places at once. ZFS checks the digital fingerprint of all the files on all of the drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with a healthy copy from a different drive from the RAID. No other file system uses checksums, so it's possible for data to become silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't have to deal with any kind of silent data corruption issues if you acquire one of our semi-dedicated server packages because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all of your files are intact at all times. A checksum is a unique digital fingerprint that is allotted to each and every file saved 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 of the drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any probability of the bad copy to be synchronized on the remaining hard disks. ZFS is the sole file system out there which uses checksums, which makes it far superior to other file systems that are unable to identify silent data corruption and duplicate bad files across drives.
