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 because the larger a hard drive is and the more info is filed on it, the much more likely it is for data to become corrupted. There're various fail-safes, but often the data gets damaged silently, so neither the particular file system, nor the administrators detect a thing. As a result, a bad file will be treated as a standard one and if the HDD is a part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get worse. When a given file gets corrupted, it will be partly or fully unreadable, therefore a text file will no longer 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 site content. Although the most widely used server file systems include various checks, they quite often fail to find some problem early enough or require a long time period in order to check all files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data that you upload to your new cloud web hosting account shall be guaranteed by the ZFS file system that we work with on our cloud platform. Most of the web hosting providers, like our company, use multiple hard drives to store content and since the drives work in a RAID, identical information is synchronized between the drives all the time. When a file on a drive becomes corrupted for some reason, yet, it is very likely that it will be duplicated on the other drives since alternative file systems do not feature special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. If a file gets damaged, 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 another hard disk drive. As this happens instantly, there's no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you acquire one of our semi-dedicated server packages, you won't have to worry about silent file corruption as we use ZFS - an advanced file system that checks all the files in real time. Whenever you upload a file to your 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 over. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no risk for any part of your content at any time. In comparison, other file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy can be replicated on the remaining disks as well and you can lose important information. Since this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
