The process of files getting corrupted as a result of some hardware or software failure is referred to as data corruption and this is among the main problems which web hosting companies face since the larger a hard disk is and the more info is kept on it, the much more likely it is for data to get corrupted. You can find a couple of fail-safes, still often the information becomes damaged silently, so neither the file system, nor the admins see a thing. Because of this, a corrupted file will be treated as a good one and if the hard disk drive is a part of a RAID, that file will be duplicated on all other drives. In principle, this is done for redundancy, but in practice the damage will be worse. The moment a 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 present a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most frequently used server file systems have various checks, they often fail to detect a problem early enough or require an extensive amount of time to be able to check all files and the server will not be functional in the meantime.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the data uploaded in every single shared web hosting
account which is created on our cloud platform since we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each file. We'll store your information on a large number of SSD drives which work in a RAID, so the very same files will exist on several places at the same time. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from another drive within 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 over time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be resistant to silent data corruption since all of our storage servers use the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each and every file. When you upload content to your account, it'll be placed on several redundant drives being employed in a RAID i.e. the files shall be the same across all disks. All copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it discovers a mismatch, that would indicate that one of the copies is damaged, it will swap that file with a healthy copy from one of the other drives. Even if there's a sudden power failure, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, extending the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
