The process of files getting damaged resulting from some hardware or software failure is called 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 filed on it, the much more likely it is for data to be corrupted. You can find a couple of fail-safes, yet often the info is damaged silently, so neither the particular file system, nor the admins notice anything. Because of this, a damaged file will be handled as a regular one and if the HDD is a part of a RAID, the file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in practice the damage will get even worse. Once a given file gets damaged, it will be partly or fully unreadable, therefore a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your site content. Although the most frequently used server file systems have various checks, they are likely to fail to discover a problem early enough or require a long time period to check all the files and the hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the info uploaded in every single hosting account that is generated on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for each and every file. We shall store your information on a large number of NVMe drives which operate in a RAID, so the very same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from another drive from the RAID. No other file system uses checksums, so it is possible for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since that can never happen on a server using ZFS, you do not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption as all of our storage servers work with the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it'll be kept on several redundant drives being employed in a RAID i.e. the files shall be the same on all disks. All of the copies of a given file will feature the same checksum on all hard drives 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 substitute that file with a healthy copy from one of the other disks. Even if there's a sudden power loss, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check which other file systems perform after some failure, prolonging the time needed for the server to return online. ZFS is the file system that can really protect your content from silent data corruption.
