Data corruption is the damage of data because of various hardware or software problems. Once a file is corrupted, it will no longer function properly, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive file 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 significant problem for website hosting servers as fails are much more likely to occur on larger in size hard drives where substantial volumes of info are stored. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as an undamaged one and it'll be copied on all the drives, making the damage permanent. A lot of the file systems that operate on web servers today often cannot identify corrupted files in real time or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most internet hosting service providers, including our firm, use multiple hard disk drives to store content and considering that the drives work in a RAID, the exact same info is synchronized between the drives at all times. In case a file on a drive is damaged for reasons unknown, yet, it's very likely that it will be copied on the other drives because alternative file systems do not offer special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the damaged copy shall be swapped with a good one from another hard drive. Since this happens right away, there is no risk for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created work with a powerful file system named ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we save all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. In case there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that this happens right away, there's no chance that a corrupted copy can remain on our website hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems work with this type of checks and furthermore, even during a file system check right after an unexpected power failure, none of them can detect silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the continual checksum monitoring makes a lenghty file system check obsolete.
