Data corruption is the damage of information because of various software or hardware fails. The moment a file gets damaged, it will no longer work properly, so an application will not start or shall give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a significant problem for web hosting servers as fails are very likely to occur on bigger hard disk drives where considerable volumes of information are stored. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as an ordinary one and it will be duplicated on all drives, making the harm permanent. Lots of the file systems that operate on web servers nowadays often are not able to find corrupted files right away or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your websites in a shared hosting account with our firm, you do not have to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. All the information that you upload will be kept in a RAID i.e. simultaneously on numerous NVMe drives. All file systems synchronize the files between the separate drives using this type of a setup, but there's no real guarantee that a file won't get corrupted. This could happen at the time of the writing process on each drive and after that a damaged copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all drives live and in the event that a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. In this way, your data will continue to be unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you purchase one of our semi-dedicated hosting plans, you will not need to be concerned about silent file corruption since we use ZFS - a high level file system which monitors all the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between several NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no danger for any part of your content at any moment. In contrast, alternative file systems perform checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you may lose precious data. Because this is not the case with ZFS, we can guarantee the integrity of each file you upload no matter what.
