Data corruption is the damage of data due to various hardware or software failures. After a file gets corrupted, it will no longer function properly, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as failures are very likely to happen on bigger hard disks where vast volumes of information are stored. If a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as a regular one and it will be duplicated on all drives, making the harm permanent. Lots of the file systems which run on web servers today often are unable to recognize corrupted files immediately or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account shall be guaranteed by the ZFS file system which we make use of on our cloud platform. The vast majority of internet hosting service providers, like our company, use multiple HDDs to store content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives all of the time. In case a file on a drive gets corrupted for some reason, yet, it's very likely that it will be duplicated on the other drives since alternative file systems do not include special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from a different disk drive. Because this happens right away, there's no possibility for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you go for one of our semi-dedicated hosting plans, you will not need to worry about silent file corruption because we use ZFS - a high level file system which keeps track of all files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a couple of NVMe drives for redundancy, so if one 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 immediately, so there will be no threat for any part of your content at any time. By comparison, all the other file systems execute checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy can be replicated on the rest of the drives as well and you could lose critical info. As this isn't the case with ZFS, we can warrant the integrity of each and every file you upload no matter what.
