Data corruption is the damage of data because of various software or hardware problems. The moment a file is damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, that makes it a serious problem for web hosting servers as fails are more likely to happen on larger in size hard disk drives where substantial volumes of info are placed. If a drive is part of a RAID and the data on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a good one and it'll be duplicated on all drives, making the damage permanent. A lot of the file systems which run on web servers these days often are unable to recognize corrupted files in real time or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account with our firm, you do not need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform works with the revolutionary ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. All data that you upload will be saved in a RAID i.e. simultaneously on a number of NVMe drives. All of the file systems synchronize the files between the separate drives with this type of a setup, but there is no real guarantee that a file will not be corrupted. This can occur during the writing process on any drive and then a bad copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all drives live and in the event that a corrupted file is found, it's substituted with a good copy with the correct checksum from another drive. That way, your information will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you acquire one of our semi-dedicated server packages, you won't need to worry about silent file corruption since we use ZFS - a high level file system which monitors all of the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a couple of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no threat for any part of your content at any time. In comparison, alternative file systems perform checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy may be replicated on the rest of the disks as well and you may lose crucial data. As this isn't the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
