Data corruption is the accidental change of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file could become partially or fully corrupted, so it will no longer work as it should since its bits will be scrambled or missing. An image file, for example, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In case such an issue appears and it's not recognized by the system or by an administrator, the data will become corrupted silently and if this happens on a drive that is a part of a RAID array where the info is synced between various drives, the corrupted file shall be duplicated on all of the other drives and the harm will be permanent. A number of widespread file systems either do not offer real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a very common problem on hosting servers where huge volumes of data are kept.

No Data Corruption & Data Integrity in Web Hosting

In case you host your sites in a web hosting account with our company, you will not need to worry about your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All data that you upload will be stored in a RAID i.e. simultaneously on a number of NVMes. All the file systems synchronize the files between the separate drives using this type of a setup, but there's no real warranty that a file will not be corrupted. This could happen throughout the writing process on each drive and then a damaged copy may be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all of the drives in real time and when a corrupted file is located, it's substituted with a good copy with the correct checksum from some other drive. This way, your information will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not encounter any silent data corruption issues in case you get one of our semi-dedicated server plans since the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all the files are undamaged all of the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As we store all content on a number of drives simultaneously, 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. If 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 probability of the bad copy to be synchronized on the rest of the drives. ZFS is the sole file system you can find that uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and duplicate bad files across hard drives.
