The process of files getting damaged due to some hardware or software failure is known as data corruption and this is one of the main problems which hosting companies face as the larger a hard drive is and the more data is filed on it, the more likely it is for data to get corrupted. You'll find several fail-safes, still often the data gets corrupted silently, so neither the file system, nor the admins see a thing. As a result, a bad file will be treated as a regular one and if the hard drive is part of a RAID, that particular file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will be even worse. The moment a file gets corrupted, it will be partially or entirely unreadable, therefore a text file will not be readable, an image file will display a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your content. Although the most commonly used server file systems feature various checks, they often fail to identify a problem early enough or require an extensive period of time to check all of the files and the server will not be functional in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the data uploaded in every single shared hosting
account which is made on our cloud platform as we use the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption thanks to a unique checksum for every single file. We will store your info on a large number of SSD drives that function in a RAID, so the very same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file is different from what it should be, the file system replaces that file with an undamaged copy from a different drive in the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't have to deal with any silent data corruption issues whatsoever if you buy one of our semi-dedicated hosting
packages since the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all files are intact all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any possibility of the corrupted copy to be synchronized on the other hard disks. ZFS is the sole file system available on the market which uses checksums, which makes it much more dependable than other file systems which are unable to detect silent data corruption and duplicate bad files across hard drives.
