The process of files getting corrupted as a result of some hardware or software failure is known as data corruption and this is one of the main problems that hosting companies face as the larger a hard drive is and the more info is stored on it, the much more likely it is for data to be corrupted. There are a couple of fail-safes, yet often the info is corrupted silently, so neither the particular file system, nor the admins detect a thing. Thus, a damaged file will be handled as a good one and if the HDD is a part of a RAID, that file will be copied on all other drives. Theoretically, this is for redundancy, but in reality the damage will be even worse. When a file gets corrupted, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will display a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most well-known server file systems feature various checks, they are likely to fail to identify some problem early enough or require an extensive period of time in order to check all files and the web hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Web Hosting
We warrant the integrity of the information uploaded in each cloud web hosting
account which is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for each file. We shall store your information on a number of SSD drives that operate in a RAID, so exactly the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with an undamaged version from some other drive within the RAID. There's no other file system that uses checksums, so it is possible for data to be silently damaged and the bad file to be replicated on all drives with time, but since this can never happen on a server running ZFS, you will not have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated hosting
account will be created employ a powerful file system named ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. Since we keep all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. If there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because it happens right away, there's no chance that a damaged copy could remain on our website hosting servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check following an unexpected power failure, none of them can detect silently corrupted files. In comparison, ZFS doesn't crash after a blackout and the constant checksum monitoring makes a lenghty file system check unneeded.
