Data corruption is the damage of info due to various software or hardware fails. The moment a file is corrupted, it will no longer function accurately, so an app will not start or will give errors, a text file can be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as fails are very likely to occur on larger in size hard drives where substantial volumes of information are kept. When a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as an ordinary one and will be copied on all the drives, making the harm permanent. Lots of the file systems that run on web servers today often are unable to identify corrupted files immediately or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data which you upload to your new shared web hosting account shall be ensured by the ZFS file system which we use on our cloud platform. The vast majority of web hosting providers, including our company, use multiple hard disks to store content and because the drives work in a RAID, the same data is synchronized between the drives all of the time. When a file on a drive gets damaged for some reason, however, it is more than likely that it will be copied on the other drives since other file systems do not have special checks for this. In contrast to them, ZFS uses 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, which means that the bad copy shall be substituted with a good one from another hard drive. Due to the fact that this happens immediately, there is no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you acquire one of our semi-dedicated server solutions, you won't have to be concerned about silent file corruption since we use ZFS - an advanced file system that checks all 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. The file will be synchronized between multiple NVMe drives for redundancy, so if one drive fails, the other ones will take control. 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 happens instantly, so there will be no danger for any part of your content at any time. In comparison, all of the other file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you can lose critical data. Since this is not the case with ZFS, we're able to warrant the integrity of each and every file you upload no matter what.
