The process of files getting corrupted because of some hardware or software failure is known as data corruption and this is one of the main problems which web hosting companies face since the larger a hard disk drive is and the more information is filed on it, the much more likely it is for data to become corrupted. You will find various fail-safes, yet often the information becomes damaged silently, so neither the particular file system, nor the administrators see anything. Because of this, a bad file will be handled as a standard one and if the HDD is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. Once a given file gets damaged, it will be partially or completely unreadable, so a text file will not be readable, an image file will display a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most frequently used server file systems include various checks, they often fail to detect a problem early enough or require a long amount of time to check all files and the web hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data that you upload to your new shared website hosting account will be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most of the hosting providers, like our firm, use multiple HDDs to store content and because the drives work in a RAID, the same info is synchronized between the drives all the time. When a file on a drive becomes damaged for some reason, however, it is very likely that it will be copied on the other drives because other file systems don't include special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the damaged copy will be substituted with a good one from a different hard disk drive. Since this happens immediately, there is no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you buy one of our semi-dedicated server packages, you will not have to worry about silent file corruption since we use ZFS - an advanced file system that monitors all of the files in real time. Each time 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 synced between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no danger for any part of your content at any time. In comparison, all the other file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the remaining drives as well and you may lose critical info. As this isn't the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
