The process of files getting corrupted resulting from some hardware or software failure is known as data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard drive is and the more info is filed on it, the more likely it is for data to be corrupted. There are a couple of fail-safes, yet often the information becomes damaged silently, so neither the file system, nor the admins see anything. Thus, a corrupted file will be treated as a regular one and if the hard disk drive 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 worse. When a given file gets damaged, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will display a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most commonly used server file systems have various checks, they quite often fail to identify some problem early enough or require a vast time period in order to check all the files and the hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Hosting
We guarantee the integrity of the information uploaded in each and every hosting
account that is generated on our cloud platform since we use the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption via a unique checksum for each file. We'll store your information on a large number of SSD drives that function in a RAID, so exactly the same files will be present on several places at once. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file is different from what it needs to be, the file system replaces that file with an undamaged version from another drive in 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 with time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not need to deal with any kind of silent data corruption issues should you buy one of our semi-dedicated server
packages because the ZFS file system that we use on our cloud hosting platform uses checksums to make sure that all of your files are undamaged all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. As we store all content on a number of drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any possibility of the bad copy to be synchronized on the other hard disks. ZFS is the sole file system you can find that uses checksums, which makes it much more dependable than other file systems that cannot identify silent data corruption and copy bad files across hard drives.
