The process of files getting corrupted because of some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face as the larger a hard disk drive is and the more info is placed on it, the much more likely it is for data to get corrupted. You will find different fail-safes, but often the info becomes damaged silently, so neither the file system, nor the admins notice a thing. As a result, a bad file will be treated as a standard one and if the hard drive is a part of a RAID, that file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will get worse. Once a file gets damaged, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will show a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your website content. Although the most popular server file systems include various checks, they frequently fail to detect some problem early enough or require a long amount of time to be able to check all the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Web Hosting
We guarantee the integrity of the info uploaded in every single web hosting
account which is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption through a unique checksum for each and every file. We shall store your info on multiple 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 drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with a healthy version from another drive within 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 replicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting damaged silently since the servers where your semi-dedicated server
account will be created work with a powerful file system known as ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we save all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. In case there is a mismatch, the damaged 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 damaged copy could remain on our website hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check right after a sudden power loss, none of them will find silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the regular checksum monitoring makes a time-consuming file system check unneeded.
