The process of files being damaged caused by some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face since the larger a hard drive is and the more data is placed on it, the more likely it is for data to get corrupted. There are different fail-safes, still often the info gets damaged silently, so neither the file system, nor the admins notice a thing. As a result, a corrupted file will be handled as a regular one and if the hard disk 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 be even worse. Once a given file gets damaged, it will be partly or fully unreadable, therefore 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, and you risk losing your content. Although the most well-known server file systems have various checks, they quite often fail to identify a problem early enough or require a vast amount of time to check all files and the hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the info uploaded in every shared hosting account which is made on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We shall store your info on a number of NVMe drives that function in a RAID, so the very same files will be present on several places at once. ZFS checks the digital fingerprint of all files on all drives in real time and if the checksum of any file differs from what it has to be, the file system swaps that file with a healthy copy from another drive inside the RAID. There's no other file system that uses checksums, so it is easy for data to become silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any risk of files getting damaged silently since the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. Since we save all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. When there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that it happens right away, there's no chance that a corrupted copy can remain on our hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems include such 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 contrast, ZFS doesn't crash after a power failure and the regular checksum monitoring makes a time-consuming file system check unneeded.
