Data corruption is the damage of information because of various software or hardware failures. After a file is damaged, it will no longer work properly, so an application will not start or will give errors, a text file shall be partially or completely 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, which makes it a serious problem for website hosting servers as failures are more likely to happen on bigger hard disks where significant volumes of information are placed. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a regular one and it will be copied on all the drives, making the harm permanent. A lot of the file systems that operate on web servers today often are unable to discover corrupted files right away or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account shall be ensured by the ZFS file system which we use on our cloud platform. The vast majority of internet hosting service providers, like our company, use multiple hard disk drives to store content and considering that the drives work in a RAID, the same info is synchronized between the drives all the time. In case a file on a drive gets damaged for whatever reason, however, it is likely that it will be copied on the other drives as alternative file systems don't offer special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy shall be replaced with a good one from another hard drive. As this happens right away, there's no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any chance of files getting corrupted silently since the servers where your semi-dedicated server account will be created use a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on numerous NVMe drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. When there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens instantly, there's no chance that a damaged copy could remain on our web servers or that it could be copied to the other drives in the RAID. None of the other file systems work with this type of checks and furthermore, even during a file system check after an unexpected blackout, none of them will detect silently corrupted files. In comparison, ZFS will not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
