The process of files getting corrupted caused by some hardware or software failure is known as data corruption and this is one of the main problems that hosting companies face since the larger a hard disk drive is and the more info is filed on it, the more likely it is for data to get corrupted. There're several fail-safes, yet often the info becomes corrupted silently, so neither the particular file system, nor the administrators notice a thing. As a result, a corrupted file will be handled as a regular one and if the hard disk is a part of a RAID, that file will be duplicated on all other disk drives. In principle, this is for redundancy, but in reality the damage will be worse. Once a given file gets corrupted, it will be partially or entirely unreadable, which means that 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, so you risk sacrificing your content. Although the most popular server file systems have various checks, they are likely to fail to identify some problem early enough or require a long amount of time to check all of the files and the hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Cloud Website Hosting
We warrant the integrity of the info uploaded in every cloud website hosting
account that is made on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption thanks to a unique checksum for each and every file. We will store your data on a number of SSD drives which work in a RAID, so the very same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the 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 version from some other drive in the RAID. There's no other file system that uses checksums, so it's easy for data to be 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 will not have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you obtain one of our semi-dedicated server
packages, you will not have to be concerned about silent file corruption because we use ZFS - an advanced file system that monitors all of the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between multiple SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when 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. By comparison, other file systems carry out checks only after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy may be replicated on the rest of the drives as well and you could lose critical info. Because this is not the case with ZFS, we guarantee the integrity of every single file you upload no matter what.
