Data corruption is the damage of information caused by various software or hardware failures. Once a file gets damaged, it will no longer work properly, so an application will not start or will give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as problems are much more likely to happen on bigger hard drives where significant volumes of information are stored. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all the drives, making the damage permanent. A huge number of the file systems that run on web servers nowadays often are unable to identify corrupted files immediately or they need time-consuming system checks through which the server is not 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 which we make use of on our cloud platform. Most of the internet hosting providers, including our firm, use multiple hard disks to keep content and since the drives work in a RAID, the same info is synchronized between the drives at all times. When a file on a drive becomes corrupted for whatever reason, however, it's more than likely that it will be reproduced on the other drives as other file systems don't have special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy shall be substituted with a good one from another drive. As this happens in real time, there is no risk for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting
account will be created work with a powerful file system called ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. In the event that there's a mismatch, the corrupted 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 damaged copy could remain on our website hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems include such checks and furthermore, even during a file system check right after an unexpected power loss, none of them will find silently corrupted files. In contrast, ZFS won't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check unnecessary.
