The process of files being corrupted due to some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face because the larger a hard disk drive is and the more information is placed on it, the much more likely it is for data to get corrupted. There're a couple of fail-safes, still often the info is corrupted silently, so neither the file system, nor the admins see a thing. Because of this, a corrupted file will be handled as a standard one and if the hard drive is part of a RAID, that file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get worse. The moment a given file gets damaged, it will be partly or fully unreadable, which means that a text file will no longer be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most frequently used server file systems feature various checks, they frequently fail to find a problem early enough or require a long amount of time to be able to check all files and the web server will not be functional for the time being.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the info uploaded in each shared hosting account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption thanks to a unique checksum for every single file. We'll store your info on a number of NVMe drives that operate in a RAID, so the very same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy copy from some other drive inside the RAID. No other file system uses checksums, so it is possible for data to become silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server using ZFS, you do not have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting corrupted silently because the servers where your semi-dedicated server account will be created employ a powerful file system named ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we store all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. When there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there's no chance that a damaged copy can remain on our website hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems include this type of checks and in addition, even during a file system check right after a sudden power loss, none of them will detect silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check unneeded.
