The process of files being damaged owing to some hardware or software failure is known as data corruption and this is among the main problems which web hosting companies face because the larger a hard drive is and the more info is filed on it, the much more likely it is for data to be corrupted. You will find several fail-safes, yet often the information is damaged silently, so neither the file system, nor the admins detect anything. As a result, a damaged file will be handled as a good one and if the HDD is part of a RAID, the file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be worse. The moment a file gets corrupted, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will show a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your website content. Although the most widely used server file systems have various checks, they quite often fail to discover a problem early enough or require an extensive period of time to check all files and the hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the info uploaded in each shared website hosting account which is generated on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for each and every file. We shall store your info on multiple SSD drives which operate in a RAID, so exactly the same files will be present on several places at once. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged copy from some other drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to become silently damaged and the bad file to be duplicated on all drives over time, but since this 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
We have avoided any probability of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we save all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. In case there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because it happens instantly, there's no chance that a damaged copy could remain on our web hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems use this kind of checks and what's more, even during a file system check after a sudden power loss, none of them can find silently corrupted files. In contrast, ZFS will not crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
