Data corruption is the unintended modification of a file or the loss of information which usually occurs during reading or writing. The reason may be hardware or software failure, and because of this, a file may become partially or completely corrupted, so it'll no longer work properly because its bits will be scrambled or lacking. 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 because its content will be unreadable, etc. If this kind of an issue appears and it is not identified by the system or by an administrator, the data will get corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the info is synced between different drives, the corrupted file shall be replicated on all of the other drives and the harm will be long term. A large number of frequently used file systems either do not feature real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where huge amounts of data are kept.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account from our company, you do not have to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform employs the cutting-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be saved in a RAID i.e. simultaneously on many different NVMe drives. All of the file systems synchronize the files between the separate drives using this type of a setup, but there's no real guarantee that a file will not get corrupted. This can happen throughout the writing process on each drive and afterwards a damaged copy can be copied on the other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives instantly and in case a corrupted file is discovered, it's swapped with a good copy with the correct checksum from another drive. That way, your info will remain intact 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 should you acquire one of our semi-dedicated server solutions since the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all the files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Since we store all content on multiple drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 without delay, avoiding any probability of the corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system on the market that uses checksums, which makes it much more reliable than other file systems which are unable to identify silent data corruption and duplicate bad files across hard drives.
