Data corruption is the damage of data due to various hardware or software fails. When a file gets corrupted, 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 fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for website hosting servers as fails are much more likely to happen on larger in size hard disks where substantial volumes of info are located. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as an undamaged one and will be duplicated on all the drives, making the harm permanent. Lots of the file systems which run on web servers these days often cannot locate corrupted files immediately or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the information uploaded in every single cloud hosting account that is generated on our cloud platform because we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption via a unique checksum for every single file. We will store your information on multiple NVMe drives that work in a RAID, so the exact same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from another drive within the RAID. No other file system uses checksums, so it is possible for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you purchase one of our semi-dedicated server solutions, you won't have to worry about silent data corruption because we use ZFS - a high level file system which monitors all files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between multiple NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no danger for any part of your content at any time. In contrast, all of the other file systems perform checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you may lose important info. Because this isn't the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
