Data corruption is the damage of information caused by various software or hardware fails. The moment a file gets damaged, it will no longer work accurately, so an app will not start or shall give errors, a text file will 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 harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for hosting servers as problems are very likely to happen on larger hard drives where vast volumes of information are kept. When a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it will be duplicated on all the drives, making the harm permanent. Lots of the file systems which operate on web servers these days often are unable to recognize corrupted files right away 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 shall be ensured by the ZFS file system that we take advantage of on our cloud platform. Most of the internet hosting service providers, including our company, use multiple hard disks to keep content and since the drives work in a RAID, the exact same information is synchronized between the drives all the time. In case a file on a drive is damaged for reasons unknown, yet, it's likely that it will be duplicated on the other drives because alternative file systems don't feature special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be substituted with a good one from a different disk drive. Because this happens right away, there is no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you get one of our semi-dedicated server
solutions, you will not have to be concerned about silent file corruption because we use ZFS - an advanced file system which keeps track of all of the files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between multiple SSD 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 when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no risk for any part of your content at any time. By comparison, all the other file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy may be replicated on the other disks as well and you could lose precious information. As this isn't the case with ZFS, we warrant the integrity of every single file you upload no matter what.
