Data corruption is the damage of data caused by various hardware or software fails. When a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as problems are more likely to occur on larger hard disks where large volumes of info are stored. When a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as an undamaged one and will be copied on all drives, making the harm permanent. Lots of the file systems that run on web servers nowadays often are unable to recognize corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data that you upload to your new cloud website hosting account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The vast majority of hosting service providers, like our firm, use multiple hard drives to store content and since the drives work in a RAID, exactly the same info is synchronized between the drives all the time. In case a file on a drive becomes corrupted for reasons unknown, yet, it's very likely that it will be copied on the other drives as other file systems do not include special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy shall be substituted with a good one from another drive. Due to the fact that 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 corrupted silently as 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 various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we store all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. In the event that there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens in real time, there is no chance that a damaged copy can remain on our website hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems work with this kind of checks and what's more, even during a file system check following an unexpected power failure, none of them will discover silently corrupted files. In comparison, ZFS will not crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check obsolete.
