The process of files getting corrupted as a result of some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard disk drive is and the more info is placed on it, the more likely it is for data to be corrupted. You will find various fail-safes, but often the information gets corrupted silently, so neither the file system, nor the admins notice a thing. Thus, a bad file will be treated as a standard one and if the hard disk is part of a RAID, that particular file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get even worse. Once a file gets damaged, it will be partly or entirely unreadable, therefore a text file will not be readable, an image file will show a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your site content. Although the most frequently used server file systems include various checks, they often fail to discover some problem early enough or require a long amount of time to be able to check all files and the server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account will be ensured by the ZFS file system which we use on our cloud platform. Most of the web hosting providers, including our firm, use multiple hard disks to keep content and considering that the drives work in a RAID, the same data is synchronized between the drives at all times. When a file on a drive is corrupted for reasons unknown, yet, it's more than likely that it will be duplicated on the other drives since alternative file systems don't have special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy will be substituted with a good one from a different hard disk. Because this happens immediately, there is no possibility for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you get one of our semi-dedicated hosting packages, you will not need to be concerned about silent file corruption as we use ZFS - a high level file system which checks 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. This file will be synced between multiple NVMe 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 instantly, so there will be no threat for any part of your content at any time. By comparison, other file systems execute checks after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the other drives as well and you could lose important information. As this is not the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
