Data corruption is the unintended modification of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file can become partially or fully corrupted, so it'll no longer function correctly since its bits shall be scrambled or missing. An image file, for example, will no longer present an actual image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. When this kind of an issue occurs and it's not found by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that's part of a RAID array where the data is synchronized between different drives, the corrupted file will be copied on all the other drives and the damage will be permanent. Many commonly used file systems either don't have real-time checks or do not have good ones which will detect a problem before the damage is done, so silent data corruption is a rather common matter on hosting servers where huge volumes of info are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

If you host your websites in a cloud web hosting account with our company, you will not have to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform uses the revolutionary ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of information that you upload will be stored in a RAID i.e. simultaneously on numerous SSD drives. All of the file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file will not get corrupted. This may happen during the writing process on any drive and then a bad copy may be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives live and if a corrupted file is found, it is substituted with a good copy with the correct checksum from some other drive. That way, your data will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you go for one of our semi-dedicated hosting solutions, you won't need to worry about silent data corruption because we use ZFS - a high level file system that keeps track of all 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. This file will be synchronized between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no risk for any part of your content at any moment. In comparison, all of the other file systems carry out checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you can lose crucial information. Because this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
