Data corruption is the damage of data due to various hardware or software problems. After a file gets corrupted, it will no longer function properly, so an app will not start or will give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as failures are much more likely to happen on larger in size hard drives where vast volumes of information are located. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and will be duplicated on all the drives, making the harm permanent. Lots of the file systems that operate on web servers today often cannot detect corrupted files instantly or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Website Hosting

We have tackled the matter of silent data corruption on all our website hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems as it is the only one in existence that checks all of the files instantly by employing 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 NVMe drives and continually synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as damaged, it's replaced immediately with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be copied on the remaining NVMes. ZFS requires lots of physical memory in order to execute the real-time checks and the advantage of our cloud web hosting platform is that we use multiple powerful servers working together. In case you host your websites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't experience any silent data corruption issues whatsoever in case you purchase one of our semi-dedicated hosting plans because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all of the files are undamaged all of the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Because we store all content on a number of drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. If 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 without delay, avoiding any possibility of the corrupted copy to be synchronized on the other drives. ZFS is the only file system you can get which uses checksums, which makes it far superior to other file systems which cannot detect silent data corruption and copy bad files across hard drives.
