Data corruption is the unintentional transformation of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file may become partially or fully corrupted, so it will no longer function as it should 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, etc. In the event that such an issue appears and it is not recognized by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that is part of a RAID array where the information is synced between various drives, the corrupted file shall be copied on all other drives and the harm will become long term. Many widespread file systems either do not offer real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common matter on web hosting servers where substantial amounts of data are stored.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account shall be ensured by the ZFS file system that we make use of on our cloud platform. Most of the hosting suppliers, including our firm, use multiple hard disks to store content and since the drives work in a RAID, the same data is synchronized between the drives all of the time. If a file on a drive is corrupted for some reason, however, it is very likely that it will be copied on the other drives since other file systems do not include special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from a different drive. As this happens instantly, there's no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not experience any kind of silent data corruption issues if you purchase one of our semi-dedicated hosting solutions because the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any chance of the corrupted copy to be synchronized on the rest of the hard drives. ZFS is the only file system out there which uses checksums, which makes it much more reliable than other file systems that cannot detect silent data corruption and duplicate bad files across hard drives.
