Data corruption is the unintended change of a file or the losing of information that often occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file could become partially or fully corrupted, so it'll no longer function as it should because its bits shall be scrambled or missing. An image file, for instance, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case such an issue appears and it's not noticed by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that is a part of a RAID array where the information is synchronized between various drives, the corrupted file shall be copied on all of the other drives and the harm will be long term. Many widespread file systems either do not feature real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where large volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data that you upload to your new cloud web hosting account shall be ensured by the ZFS file system which we use on our cloud platform. Most of the hosting suppliers, like our company, use multiple hard disk drives to keep content and since the drives work in a RAID, identical info is synchronized between the drives at all times. When a file on a drive gets damaged for some reason, however, it is likely that it will be reproduced on the other drives because alternative file systems don't offer special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy will be replaced with a good one from a different disk drive. Because this happens right away, there is no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you purchase one of our semi-dedicated hosting packages, you won't need to be concerned about silent file corruption since we use ZFS - an advanced file system which checks all the files in real time. Each time 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 synchronized between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no risk for any part of your content at any moment. By comparison, other file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you may lose precious data. Since this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
