Data corruption is the unintentional modification of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software malfunction, and due to this fact, a file can become partially or completely corrupted, so it'll no longer function as it should because its bits will 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 since its content will be unreadable, etc. In the event that such a problem occurs and it's not recognized by the system or by an admin, the data will be corrupted silently and in case this happens on a drive which is a part of a RAID array where the information is synced between different drives, the corrupted file shall be copied on all other drives and the damage will be permanent. A number of widespread file systems either do not feature real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a very common matter on hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Hosting

If you host your sites in a hosting account from our company, you don't have to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. All information that you upload will be kept in a RAID i.e. simultaneously on a large number of NVMes. Many file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file will not be corrupted. This could occur during the writing process on any drive and after that a bad copy may be copied on all other drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all of the drives immediately and in case a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. This way, your data will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't encounter any kind of silent data corruption issues whatsoever in case you buy one of our semi-dedicated server solutions because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all of the files are intact at all times. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. Because we store all content on a number of drives at the same time, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the remaining hard drives. ZFS is the only file system out there that uses checksums, which makes it much more dependable than other file systems that are not able to identify silent data corruption and copy bad files across hard drives.
