Data corruption is the damage of info caused by various software or hardware fails. When a file is damaged, it will no longer work as it should, so an app will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a serious problem for hosting servers as failures are more likely to happen on bigger hard drives where significant volumes of information are kept. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and will be copied on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers these days often are unable to recognize corrupted files in real time or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data that you upload to your new shared website hosting account will be ensured by the ZFS file system which we take advantage of on our cloud platform. Most of the hosting suppliers, including our firm, use multiple hard disk drives to keep content and since the drives work in a RAID, identical info is synchronized between the drives at all times. When a file on a drive becomes corrupted for whatever reason, yet, it is very likely that it will be reproduced on the other drives because other file systems don't feature special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the damaged copy will be swapped with a good one from another hard disk. As this happens immediately, there is no risk for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any possibility of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we store all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. If there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens right away, there's no chance that a corrupted copy can remain on our website hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems use this type of checks and in addition, even during a file system check after a sudden electrical power failure, none of them will identify silently corrupted files. In comparison, ZFS doesn't crash after a power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
