The process of files being damaged because of some hardware or software failure is known as data corruption and this is one of the main problems that hosting companies face because the larger a hard disk drive is and the more data is placed on it, the much more likely it is for data to be corrupted. There're different fail-safes, but often the info becomes damaged silently, so neither the file system, nor the administrators detect a thing. Thus, a bad file will be treated as a standard one and if the hard disk drive is part of a RAID, that file will be copied on all other disk drives. In theory, this is done for redundancy, but in reality the damage will get worse. Once some file gets corrupted, it will be partially or completely unreadable, so a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most well-known server file systems feature various checks, they often fail to find some problem early enough or require a long amount of time in order to check all of the files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the info uploaded in every single cloud website hosting
account that is generated on our cloud platform since we employ the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for every single file. We shall store your data on a number of SSD drives that operate in a RAID, so exactly the same files will be available on several places at the same time. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file differs from what it should be, the file system swaps that file with a healthy version from some other drive in 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 with time, but since this can never happen on a server using ZFS, you will not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not have to deal with any silent data corruption issues should you purchase one of our semi-dedicated hosting
solutions because the ZFS file system that we work with on our cloud hosting platform uses checksums in order to ensure that all of your files are intact at all times. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As 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 right away, avoiding any probability of the corrupted copy to be synchronized on the remaining hard disks. ZFS is the sole file system you can find which uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and copy bad files across hard drives.
