Data corruption is the damage of information caused by various software or hardware failures. Once a file gets damaged, it will no longer function properly, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and 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 web hosting servers as fails are more likely to occur on larger hard drives where considerable volumes of info are located. When a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as a healthy one and it'll be duplicated on all the drives, making the damage permanent. Lots of the file systems which run on web servers these days often are unable to locate corrupted files right away or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account with our firm, you do not have to worry about your data ever getting damaged. We can guarantee that since our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. Any info that you upload will be saved in a RAID i.e. simultaneously on numerous NVMes. All of the file systems synchronize the files between the different drives using this type of a setup, but there is no real guarantee that a file will not get corrupted. This could happen throughout the writing process on each drive and afterwards a bad copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives instantly and in the event that a corrupted file is identified, it is swapped with a good copy with the correct checksum from another drive. In this way, your info will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you purchase one of our semi-dedicated hosting packages, you will not have to be concerned about silent data corruption as we use ZFS - an advanced file system that keeps track of all the files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between several NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no danger for any part of your content at any time. In contrast, alternative file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the other drives as well and you could lose precious info. As this is not the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
