No Data Corruption & Data Integrity
Find out what No Data Corruption & Data Integrity is and how it could be good for the files inside your website hosting account.
Data corruption is the damage of info caused by various software or hardware failures. When a file gets damaged, it will no longer function correctly, so an application will not start or shall give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, which makes it a serious problem for hosting servers as problems are very likely to occur on larger hard drives where considerable volumes of information are kept. In case a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is likely that the damaged file will be treated as a regular one and it will be duplicated on all drives, making the harm permanent. Lots of the file systems which operate on web servers today often cannot find corrupted files in real time or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
We have resolved the problem of silent data corruption on all our cloud web hosting
servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one out there which checks all of the files instantly by using a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll 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 damaged, it's replaced immediately with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the other SSDs. ZFS requires plenty of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we work with multiple very 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 Hosting
If you go for one of our semi-dedicated hosting
solutions, you won't have to be concerned about silent data corruption as we use ZFS - a high level file system which checks all of the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens instantly, so there will be no danger for any part of your content at any time. In comparison, alternative file systems perform checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you may lose precious information. Because this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
