The process of files being corrupted owing to some hardware or software failure is called data corruption and this is among the main problems which Internet hosting companies face as the larger a hard drive is and the more data is filed on it, the more likely it is for data to be corrupted. You'll find different fail-safes, yet often the info gets damaged silently, so neither the file system, nor the administrators see a thing. As a result, a damaged file will be treated as a good one and if the hard drive is part of a RAID, the file will be copied on all other drives. In principle, this is for redundancy, but in practice the damage will get even worse. Once a given file gets damaged, it will be partially or entirely unreadable, therefore a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most commonly used server file systems include various checks, they are likely to fail to discover some problem early enough or require an extensive amount of time 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 warrant the integrity of the info uploaded in each and every hosting account which is made on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption through a unique checksum for each file. We shall store your info on multiple SSD drives which operate in a RAID, so exactly the 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 in the event that the checksum of any file is different from what it should be, the file system swaps that file with an undamaged copy from some other drive in the RAID. There's no other file system which uses checksums, so it's easy for data to become silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you acquire one of our semi-dedicated server solutions, you will not need to worry about silent file corruption since we use ZFS - a high level file system which monitors all the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a number of SSD drives for redundancy, so if a 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 another drive. This happens right away, so there will be no risk for any part of your content at any moment. By comparison, all the other file systems carry out checks only after a system malfunction, but since they do not 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 can lose critical data. Since this isn't the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
