The process of files getting damaged resulting from some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face since the larger a hard drive is and the more data is placed on it, the more likely it is for data to be corrupted. You can find different fail-safes, but often the data gets damaged silently, so neither the file system, nor the admins see anything. Thus, a bad file will be treated as a good one and if the hard drive is a part of a RAID, that file will be copied on all other drives. Theoretically, this is for redundancy, but in practice the damage will get even worse. The moment some file gets corrupted, it will be partly or entirely unreadable, which means that a text file will no longer be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most well-known server file systems feature various checks, they quite often fail to discover a problem early enough or require a long time period to check all the files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Web Hosting

We warrant the integrity of the info uploaded in any cloud web hosting account that is created on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption through a unique checksum for each and every file. We shall store your info on a number of SSD drives that operate in a RAID, so the exact same files will be available on several places at the same time. 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 has to be, the file system replaces that file with a healthy version from some other drive inside the RAID. No other file system uses checksums, so it's possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any possibility of files getting damaged silently because the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its 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 store all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. If there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there's no chance that a damaged copy can remain on our web servers or that it could be copied to the other hard drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check after a sudden power loss, none of them will detect silently corrupted files. In comparison, ZFS does not crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
