Data corruption is the damage of information caused by various software or hardware fails. Once a file gets damaged, it will no longer work accurately, so an app will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for hosting servers as fails are much more likely to occur on larger hard disk drives where large volumes of info are placed. In case a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and it will be copied on all the drives, making the harm permanent. Lots of the file systems which run on web servers today often are unable to detect corrupted files in real time or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data which you upload to your new cloud website hosting account will be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of hosting service providers, including our company, use multiple hard disk drives to keep content and since the drives work in a RAID, exactly the same information is synchronized between the drives all the time. In case a file on a drive becomes damaged for reasons unknown, however, it's more than likely that it will be duplicated on the other drives as alternative file systems do not offer special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the damaged copy will be replaced with a good one from a different hard drive. Since this happens instantly, there's no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any risk of files getting damaged silently since the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system known as ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. In case there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because it happens in real time, there is no chance that a corrupted copy could remain on our hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with such checks and what's more, even during a file system check following a sudden power loss, none of them will discover silently corrupted files. In contrast, ZFS won't crash after a power loss and the regular checksum monitoring makes a lenghty file system check obsolete.
