The process of files being damaged as a result of some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard disk is and the more information is placed on it, the much more likely it is for data to be corrupted. There're different fail-safes, still often the data is corrupted silently, so neither the particular file system, nor the admins see a thing. Thus, a corrupted file will be handled as a good one and if the HDD is a part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. The moment some file gets corrupted, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most widespread server file systems include various checks, they often fail to discover a problem early enough or require a long time period to check all the files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the data uploaded in every single cloud website hosting
account that is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption via a unique checksum for each and every file. We shall store your data on a number of SSD drives which work in a RAID, so the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from some other drive inside the RAID. No other file system uses checksums, so it is easy for data to become silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you go for one of our semi-dedicated server
solutions, you will not need to be concerned about silent data corruption because we use ZFS - an advanced file system that monitors all files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no threat for any part of your content at any moment. By comparison, other file systems perform checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you may lose important data. As this is not the case with ZFS, we can warrant the integrity of each file you upload no matter what.
