The process of files being damaged due to some hardware or software failure is called data corruption and this is one of the main problems which Internet hosting companies face as the larger a hard disk is and the more information is placed on it, the much more likely it is for data to become corrupted. You can find several fail-safes, still often the data gets corrupted silently, so neither the file system, nor the admins detect a thing. As a result, a bad file will be treated as a regular one and if the hard drive is part of a RAID, that particular file will be copied on all other disk drives. In principle, this is done for redundancy, but in practice the damage will get worse. Once a file gets damaged, it will be partly or fully unreadable, so a text file will not be readable, an image file will present a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your content. Although the most well-known server file systems feature various checks, they are likely to fail to discover some problem early enough or require a long time period to be able to check all files and the web hosting server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your sites in a shared hosting account from our firm, you don't have to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All data that you upload will be stored in a RAID i.e. simultaneously on a number of NVMes. All file systems synchronize the files between the different drives with this type of a setup, but there's no real warranty that a file will not get corrupted. This could occur at the time of the writing process on any drive and afterwards a damaged copy can be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives immediately and in case a corrupted file is located, it is swapped with a good copy with the correct checksum from some other drive. In this way, your information will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't experience any kind of silent data corruption issues should you acquire one of our semi-dedicated server packages as the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all files are intact all the time. A checksum is a unique digital fingerprint that is allotted 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 uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that 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 chance of the bad copy to be synchronized on the rest of the hard disks. ZFS is the only file system you will find which uses checksums, which makes it much more dependable than other file systems that are unable to identify silent data corruption and copy bad files across drives.
