The process of files being corrupted as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems that web hosting companies face because the larger a hard disk drive is and the more information is filed on it, the more likely it is for data to become corrupted. There're a couple of fail-safes, but often the data gets corrupted silently, so neither the particular file system, nor the administrators detect a thing. As a result, a damaged file will be treated as a good one and if the hard drive is a part of a RAID, that particular file will be copied on all other drives. In theory, this is done for redundancy, but in reality the damage will be worse. When some file gets damaged, it will be partly or completely unreadable, therefore a text file will no longer be readable, an image file will show a random blend 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 have various checks, they frequently fail to discover some problem early enough or require an extensive amount of time to check all of the files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Hosting

The integrity of the data that you upload to your new hosting account shall be guaranteed by the ZFS file system which we use on our cloud platform. The majority of hosting providers, like our firm, use multiple hard disk drives to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives at all times. If a file on a drive becomes corrupted for reasons unknown, however, it's likely that it will be duplicated on the other drives as alternative file systems don't include special checks for that. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the damaged copy shall be swapped with a good one from a different hard disk drive. Because this happens in real time, there is no risk 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 plans, you won't have to worry about silent data corruption because we use ZFS - an advanced file system that checks 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 several SSD 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 damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no threat for any part of your content at any time. In contrast, all of the 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 cannot detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you can lose important information. As this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
