Data corruption is the unintended transformation of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file may become partially or fully corrupted, so it will no longer work correctly as its bits will be scrambled or missing. An image file, for instance, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. If this kind of a problem appears and it's not recognized by the system or by an admin, the data will be corrupted silently and in case this happens on a drive that's part of a RAID array where the information is synced between various drives, the corrupted file shall be reproduced on all other drives and the harm will become permanent. A large number of frequently used file systems either don't have real-time checks or do not have good ones that can detect an issue before the damage is done, so silent data corruption is a rather common issue on hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data that you upload to your new cloud web hosting account will be ensured by the ZFS file system that we employ on our cloud platform. Most of the web hosting suppliers, including our company, use multiple HDDs to keep content and because the drives work in a RAID, exactly the same data is synchronized between the drives at all times. When a file on a drive gets damaged for reasons unknown, however, it is more than likely that it will be reproduced on the other drives since alternative file systems don't feature special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from another hard disk. As this happens immediately, there's no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you go for one of our semi-dedicated server solutions, you won't need to be concerned about silent file corruption because we use ZFS - an advanced file system that keeps track of all of the files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized 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 corrupted 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 moment. In comparison, other file systems carry out checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy could be replicated on the rest of the drives as well and you may lose important info. As this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
