Data corruption is the unintended modification of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it will no longer function properly because its bits will be scrambled or lost. An image file, for instance, will no longer present an authentic 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 this kind of an issue occurs and it's not identified by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive which is part of a RAID array where the information is synchronized between various different drives, the corrupted file will be replicated on all other drives and the damage will become long term. Many frequently used file systems either do not offer real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large volumes of data are kept.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account with our company, you will not have to worry about your data ever getting corrupted. We can guarantee that as our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. Any info that you upload will be kept in a RAID i.e. simultaneously on many different 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 won't get corrupted. This can happen at the time of the writing process on any drive and after that a corrupted copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all drives instantly and if a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. That way, your info will continue to be 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 have to be concerned about silent file corruption since we use ZFS - a high level file system which checks all files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a number of NVMe 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 when it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no risk for any part of your content at any time. In comparison, all of the other file systems perform checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the remaining disks as well and you can lose important information. As this isn't the case with ZFS, we warrant the integrity of each and every file you upload no matter what.
