Data corruption is the damage of information due to various software or hardware failures. The moment a file gets damaged, it will no longer function as it should, so an app will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, which makes it a serious problem for web hosting servers as problems are more likely to happen on larger hard disk drives where significant volumes of info are located. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a healthy one and it will be copied on all drives, making the damage permanent. A huge number of the file systems that operate on web servers nowadays often are not able to detect corrupted files right away 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 that you upload to your new cloud hosting account will be ensured by the ZFS file system which we take advantage of on our cloud platform. Most web hosting service providers, including our company, use multiple hard disk drives to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives all of the time. In case a file on a drive gets damaged for whatever reason, however, it is likely that it will be duplicated on the other drives as alternative file systems do not have special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy will be substituted with a good one from another drive. Because this happens right away, there's no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any probability of files getting damaged silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. Since we save all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. When there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since it happens instantly, there's no chance that a corrupted copy could remain on our web hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems include such checks and what is more, even during a file system check after an unexpected electrical power failure, none of them can discover silently corrupted files. In comparison, ZFS won't crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
