Data corruption is the damage of information because of various software or hardware failures. After a file is damaged, it will no longer function properly, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, that makes it a significant problem for website hosting servers as failures are much more likely to occur on larger in size hard disks where considerable volumes of info are stored. When a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it is likely that the bad file will be treated as a standard one and it'll be copied on all drives, making the damage permanent. Lots of the file systems that run on web servers these days often cannot recognize corrupted files immediately or they need time-consuming system checks during which the server is not functioning.
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 use on our cloud platform. Most web hosting suppliers, like our firm, use multiple hard drives to store content and considering that the drives work in a RAID, identical data is synchronized between the drives all of the time. In case a file on a drive gets damaged for whatever reason, yet, it's very likely that it will be copied on the other drives since other file systems don't feature special checks for this. Unlike them, ZFS applies 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, which means that the damaged copy shall be swapped with a good one from another drive. Since this happens in real time, there's no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you purchase one of our semi-dedicated server packages, you won't need to be concerned about silent file corruption since we use ZFS - a high level file system that keeps track of all files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no danger for any part of your content at any time. In comparison, other file systems execute checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you may lose important information. As this isn't the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
