The process of files getting corrupted resulting from some hardware or software failure is known as data corruption and this is among the main problems that Internet hosting companies face since the larger a hard drive is and the more info is filed on it, the more likely it is for data to be corrupted. There're several fail-safes, but often the info becomes damaged silently, so neither the file system, nor the admins notice a thing. As a result, a corrupted file will be treated as a good one and if the hard disk is part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will get worse. Once some file gets corrupted, it will be partly or fully unreadable, therefore a text file will not be readable, an image file will show a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most frequently used server file systems include various checks, they quite often fail to detect a problem early enough or require an extensive time period to check all files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the info uploaded in each and every cloud hosting account that is generated on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption thanks to a unique checksum for every single file. We will store your data on a number of SSD drives that function in a RAID, so identical files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy version from a different drive from the RAID. There's no other file system which uses checksums, so it's easy for data to become silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any possibility of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created employ a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. 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 this happens in real time, there's no chance that a corrupted copy could remain on our web hosting servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems use this kind of checks and in addition, even during a file system check following an unexpected blackout, none of them will discover silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the regular checksum monitoring makes a lenghty file system check unnecessary.
