The process of files being damaged as a consequence of some hardware or software failure is called data corruption and this is among the main problems which Internet hosting companies face as the larger a hard disk is and the more information is kept on it, the much more likely it is for data to get corrupted. You'll find various fail-safes, but often the info becomes corrupted silently, so neither the file system, nor the admins notice anything. Consequently, a damaged file will be treated as a good one and if the HDD is part of a RAID, that 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 partially or completely unreadable, which means that 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, and you risk losing your website content. Although the most popular server file systems feature various checks, they often fail to detect some problem early enough or require an extensive period of time in order to check all the files and the web server will not be functional in the meantime.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the info uploaded in every single website hosting account that is made on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for each and every file. We shall store your information on multiple NVMe drives that function in a RAID, so exactly the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all of the files on all drives in real time and in case the checksum of any file is different from what it should be, the file system replaces that file with an undamaged version from a different drive from the RAID. There's no other file system that uses checksums, so it's easy for data to be silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be resistant to silent data corruption since all our storage servers use the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each file. When you upload content to your account, it'll be saved on several redundant drives in a RAID i.e. the files will be the same across all disk drives. All of the copies of a particular file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies quickly, so if it discovers a mismatch, that will indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other disks. Even if there is an unforeseen power failure, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, extending the time needed for the server to return online. ZFS is the file system which can really protect your content from silent data corruption.
