Data corruption is the damage of data due to various software or hardware problems. After a file is damaged, it will no longer work accurately, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as failures are very likely to happen on larger in size hard disk drives where vast volumes of information are stored. In case a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the bad file will be treated as a healthy one and will be copied on all the drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often cannot find corrupted files instantly or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Website Hosting

We've resolved the matter of silent data corruption on all of our website 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 in existence 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'll be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS constantly compares the checksum of all files and in the event that any file is detected as corrupted, it's replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other SSDs. ZFS requires plenty of physical memory to perform the real-time checks and the advantage of our cloud website hosting platform is that we use multiple powerful servers working together. If you host your websites with us, your info will be undamaged no matter what.
