Data corruption is the unintentional modification of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software malfunction, and as a result, a file could become partially or fully corrupted, so it'll no longer function properly because its bits shall be scrambled or missing. An image file, for instance, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that this kind of a problem occurs and it is not identified by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive which is a part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be reproduced on all of the other drives and the harm will be permanent. A number of frequently used file systems either do not have real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

If you host your websites in a shared web hosting account from our firm, you do not have to worry about any of your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform works with the reliable ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any info that you upload will be stored in a RAID i.e. simultaneously on many NVMe drives. Many file systems synchronize the files between the separate drives using this kind of a setup, but there is no real warranty that a file will not get corrupted. This could occur at the time of the writing process on each drive and afterwards a bad copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives right away and in the event that a corrupted file is found, it is substituted with a good copy with the correct checksum from another drive. That way, your data will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you go for one of our semi-dedicated hosting packages, you won't have to worry about silent data corruption as we use ZFS - a high level file system which monitors all files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of 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 in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no risk for any part of your content at any moment. By comparison, all of the other file systems execute checks after a system breakdown, but since they do not 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 disks as well and you can lose precious info. As this is not the case with ZFS, we're able to warrant the integrity of each file you upload no matter what.
