The process of files being damaged caused by some hardware or software failure is referred to as data corruption and this is among the main problems which Internet hosting companies face since the larger a hard disk drive is and the more data is filed on it, the more likely it is for data to be corrupted. You will find various fail-safes, but often the information becomes damaged silently, so neither the file system, nor the admins see a thing. Thus, a bad file will be handled as a standard one and if the hard disk is part of a RAID, that file will be duplicated on all other drives. In principle, this is done for redundancy, but in practice the damage will get even worse. When a given file gets corrupted, it will be partially or entirely unreadable, therefore a text file will not be readable, an image file will show a random blend of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your website content. Although the most commonly used server file systems feature various checks, they are likely to fail to find a problem early enough or require an extensive period of time to be able to check all the files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

We've dealt with the matter of silent data corruption on all our cloud hosting servers by using the amazing Z file system, or ZFS. The latter is better than other file systems since it is the only one on the market that checks all the files right away by using a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as damaged, it's replaced right away with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the rest of the SSDs. ZFS requires plenty of physical memory in order to execute the real-time checks and the advantage of our cloud hosting platform is that we employ multiple powerful servers working together. If you host your websites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not encounter any silent data corruption issues whatsoever in case you purchase one of our semi-dedicated server plans due to the fact that 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 undamaged all the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the damaged copy to be synchronized on the other hard disks. ZFS is the only file system you will find which uses checksums, which makes it much more reliable than other file systems that are unable to detect silent data corruption and duplicate bad files across drives.
