Data corruption is the unintentional change of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software fail, and as a consequence, a file may become partially or fully corrupted, so it'll no longer function properly since its bits will be scrambled or lacking. An image file, for example, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. When such a problem occurs and it isn't identified by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that's a part of a RAID array where the info is synced between various drives, the corrupted file will be reproduced on all other drives and the harm will become long term. A large number of widely used file systems either do not feature real-time checks or don't have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common problem on web hosting servers where substantial amounts of info are stored.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your websites in a shared website hosting account with our firm, you won't have to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. All the info that you upload will be kept in a RAID i.e. simultaneously on many different SSD drives. All of the file systems synchronize the files between the different drives with such a setup, but there's no real guarantee that a file won't be corrupted. This can occur at the time of the writing process on any drive and afterwards a damaged copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all of the drives in real time and in the event that a corrupted file is discovered, it is substituted with a good copy with the correct checksum from another drive. This way, your information will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you purchase one of our semi-dedicated hosting solutions, you will not need to worry about silent file corruption as we use ZFS - a high level file system that checks all of 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 synced between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the 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 risk for any part of your content at any moment. In comparison, all of the other file systems execute checks after a system malfunction, but since they don't use anything similar to the checksums which 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 could lose critical data. Because this isn't the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
