No Data Corruption & Data Integrity
Discover what No Data Corruption & Data Integrity is and how it can be good for the files within your web hosting account.
The process of files being corrupted caused by some hardware or software failure is called data corruption and this is one of the main problems which Internet hosting companies face as the larger a hard disk drive is and the more info is filed on it, the much more likely it is for data to get corrupted. You can find a couple of fail-safes, yet often the info gets corrupted silently, so neither the particular file system, nor the admins detect anything. Thus, a damaged file will be treated as a regular one and if the hard drive is part of a RAID, that particular file will be copied on all other disk drives. Theoretically, this is for redundancy, but in reality the damage will be even worse. The moment a file gets corrupted, it will be partially or entirely unreadable, which means that a text file will not be readable, an image file will present a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your content. Although the most commonly used server file systems have various checks, they quite often fail to discover a problem early enough or require a vast period of time to be able to check all files and the web hosting server will not be operational for the time being.

No Data Corruption & Data Integrity in Hosting
We guarantee the integrity of the info uploaded in every single
hosting account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We'll store your information on a number of SSD drives which work in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all files on all 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 a healthy version from some other drive within the RAID. There's no other file system which uses checksums, so it is possible for data to become silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you won't have to worry about the integrity of your data.

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 that keeps track of all of the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The 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 in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no danger for any part of your content at any moment. In comparison, all the other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the other drives as well and you may lose crucial info. As this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
