Data corruption is the damage of data due to various hardware or software failures. Once a file gets corrupted, it will no longer work correctly, so an app will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, which makes it a serious problem for web hosting servers as fails are much more likely to happen on larger in size hard disk drives where substantial volumes of information are stored. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as an ordinary one and will be duplicated on all the drives, making the damage permanent. A huge number of the file systems that operate on web servers these days often are unable to detect corrupted files right away or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data that you upload to your new cloud web hosting account shall be guaranteed by the ZFS file system which we make use of on our cloud platform. Most of the hosting service providers, including our company, use multiple HDDs to keep content and since the drives work in a RAID, identical data is synchronized between the drives at all times. When a file on a drive becomes damaged for some reason, however, it is more than likely that it will be copied on the other drives as alternative file systems do not offer special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be substituted with a good one from a different disk drive. Since this happens instantly, there is no risk for any of your files to ever get 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 data corruption as we use ZFS - an advanced file system that keeps track of all of the 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. The file will be synced between multiple SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no danger for any part of your content at any time. In contrast, alternative file systems carry out checks only after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a bad copy could be replicated on the remaining drives as well and you could lose important data. Since this isn't the case with ZFS, we warrant the integrity of each file you upload no matter what.
