Data corruption is the damage of info caused by various hardware or software fails. After a file is corrupted, it will no longer work correctly, so an app will not start or will give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as fails are much more likely to occur on larger in size hard drives where significant volumes of info are stored. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is likely that the damaged file will be treated as a standard one and will be duplicated on all drives, making the damage permanent. A lot of the file systems that run on web servers nowadays often cannot locate corrupted files in real time or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting account will be guaranteed by the ZFS file system that we work with on our cloud platform. The vast majority of internet hosting suppliers, like our firm, use multiple HDDs to store content and considering that the drives work in a RAID, the same data is synchronized between the drives all the time. In case a file on a drive becomes corrupted for reasons unknown, however, it is more than likely that it will be duplicated on the other drives because alternative file systems do not include special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. In case 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 a different disk drive. Since this happens instantly, there is no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any chance of files getting corrupted silently as the servers where your semi-dedicated server account will be created use a powerful file system called ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we keep all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. In the event that there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since this happens instantly, 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 this kind of checks and furthermore, even during a file system check right after a sudden power loss, none of them will discover silently corrupted files. In contrast, ZFS does not crash after a power loss and the continual checksum monitoring makes a lenghty file system check unneeded.
