The process of files getting damaged as a result of some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face because the larger a hard drive is and the more information is placed on it, the much more likely it is for data to become corrupted. You can find a couple of fail-safes, yet often the information becomes damaged silently, so neither the file system, nor the admins detect anything. Because of this, a bad file will be handled as a good one and if the hard disk drive is a part of a RAID, that file will be copied on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will get even worse. When a file gets damaged, it will be partly or fully unreadable, so a text file will no longer 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, and you risk losing your content. Although the most widely used server file systems include various checks, they often fail to find some problem early enough or require a vast period of time to be able to check all the files and the web hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the info uploaded in every single 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 that was designed to avert silent data corruption through a unique checksum for each and every file. We shall store your data on a large number of NVMe drives which operate in a RAID, so the exact same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged copy from some other drive from the RAID. No other file system uses checksums, so it's possible for data to get silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you get one of our semi-dedicated hosting plans, you will not have to be concerned about silent data corruption as we use ZFS - a high level file system that monitors all of the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no risk for any part of your content at any moment. In comparison, all of the other file systems carry out checks after a system malfunction, 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 rest of the drives as well and you could lose crucial information. As this is not the case with ZFS, we guarantee the integrity of every single file you upload no matter what.
