Data corruption is the damage of info caused by various software or hardware fails. Once a file is corrupted, it will no longer work accurately, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, that makes it a serious problem for hosting servers as problems are very likely to occur on larger hard disks where substantial volumes of information are stored. In case a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's likely that the bad file will be treated as an ordinary one and it will be copied on all drives, making the damage permanent. Lots of the file systems that run on web servers nowadays often are not able to discover corrupted files instantly or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the info uploaded in every cloud hosting account which is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption through a unique checksum for each file. We shall store your data on a large number of NVMe drives that function in a RAID, so identical files will exist on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged copy from another drive in the RAID. No other file system uses checksums, so it's possible for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created employ a powerful file system called ZFS. Its key 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 keep all content on a number of 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 stored. In the event that there is a mismatch, the bad copy is replaced with a good one from one of the other drives and because it happens instantly, there is no chance that a corrupted copy can remain on our web hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check following a sudden power failure, none of them will find silently corrupted files. In comparison, ZFS doesn't crash after a power loss and the continual checksum monitoring makes a lenghty file system check obsolete.
