The process of files getting damaged owing to some hardware or software failure is referred to as data corruption and this is one of the main problems which Internet hosting companies face as the larger a hard disk is and the more info is kept on it, the more likely it is for data to become corrupted. You can find various fail-safes, yet often the info gets damaged silently, so neither the particular file system, nor the admins detect a thing. Thus, a corrupted file will be handled as a regular one and if the hard disk drive is part of a RAID, the file will be duplicated on all other disk drives. In theory, this is done for redundancy, but in practice the damage will be worse. Once a given file gets corrupted, it will be partly or entirely unreadable, which means that a text file will no longer be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your content. Although the most commonly used server file systems have various checks, they quite often fail to discover some problem early enough or require a long amount of time to be able to check all files and the hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the info uploaded in every single cloud hosting account that is made on our cloud platform due to the fact that 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 shall store your data on a large number of NVMe drives which function in a RAID, so the very same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system replaces that file with a healthy version from another drive within the RAID. No other file system uses checksums, so it's easy for data to become silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you acquire one of our semi-dedicated hosting solutions, you will not need to worry about silent data corruption as we use ZFS - a high level file system which keeps track of all files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a couple of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no danger for any part of your content at any moment. In comparison, all the other file systems perform checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you can lose precious information. Because this is not the case with ZFS, we can warrant the integrity of each and every file you upload no matter what.
