The process of files being corrupted resulting from some hardware or software failure is referred to as data corruption and this is among the main problems that web hosting companies face because the larger a hard disk drive is and the more info is kept on it, the more likely it is for data to become corrupted. You will find several fail-safes, still often the information becomes corrupted silently, so neither the file system, nor the admins detect a thing. Consequently, a damaged file will be handled as a good one and if the hard disk drive is part of a RAID, that particular file will be copied on all other disk drives. In principle, this is for redundancy, but in reality the damage will get even worse. The moment some file gets damaged, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will present a random blend of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most well-known server file systems include various checks, they are likely to fail to discover a problem early enough or require a long amount of time to check all the files and the web hosting server will not be functional for the time being.
No Data Corruption & Data Integrity in Web Hosting
We warrant the integrity of the data uploaded in any web hosting account that is made on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each file. We shall store your data on a number of NVMe drives which operate in a RAID, so the same files will be accessible on several places at once. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from a different drive inside the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't experience any silent data corruption issues in case you get one of our semi-dedicated hosting solutions since the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all of your files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any probability of the bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you can find which uses checksums, which makes it much more reliable than other file systems which cannot identify silent data corruption and copy bad files across hard drives.
