The process of files getting damaged caused by some hardware or software failure is known as data corruption and this is one of the main problems which hosting companies face as the larger a hard disk is and the more information is placed on it, the more likely it is for data to be corrupted. There're a couple of fail-safes, yet often the information is corrupted silently, so neither the particular file system, nor the administrators detect anything. As a result, a corrupted file will be treated as a good one and if the hard disk is part of a RAID, the file will be duplicated on all other disk drives. In principle, this is for redundancy, but in practice the damage will get even worse. The moment a given file gets damaged, it will be partially or completely unreadable, so a text file will no longer be readable, an image file will show a random combination of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most widespread server file systems have various checks, they often fail to discover some problem early enough or require a long time period to be able to check all files and the server will not be functional for the time being.
No Data Corruption & Data Integrity in Shared Website Hosting
We guarantee the integrity of the data uploaded in any shared website hosting
account which is generated on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption via a unique checksum for every single file. We will store your info on a number of SSD drives which function in a RAID, so the very same files will be available on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from another drive inside the RAID. No other file system uses checksums, so it is easy for data to become 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 will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you purchase one of our semi-dedicated hosting
plans, you will not have to worry about silent file corruption as we use ZFS - an advanced file system which keeps track of all the 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 synchronized between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no risk for any part of your content at any moment. By comparison, other file systems perform checks after a system failure, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the rest of the drives as well and you may lose critical information. As this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
