Data corruption is the damage of information because of various software or hardware fails. When a file gets corrupted, it will no longer work as it should, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as problems are more likely to occur on bigger hard disks where considerable volumes of information are located. If a drive is part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a healthy one and will be copied on all the drives, making the harm permanent. A huge number of the file systems which run on web servers these days often cannot find corrupted files in real time or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Cloud Hosting

We have dealt with the matter of silent data corruption on all of our cloud hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is better than other file systems since it is the only one out there which checks all the files immediately by using a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it will be stored on several SSD drives and continually synced between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as corrupted, it is replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the remaining SSDs. ZFS needs lots of physical memory to execute the real-time checks and the benefit of our cloud website hosting platform is that we use multiple powerful servers working together. In case you host your websites with us, your info will be intact no matter what.
