Data corruption is the accidental transformation of a file or the loss of information that usually occurs during reading or writing. The reason could be hardware or software fail, and due to this fact, a file could become partially or completely corrupted, so it will no longer work as it should since its bits will be scrambled or lacking. An image file, for instance, will no longer show 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, etc. In case this kind of a problem occurs and it isn't found by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the info is synchronized between various drives, the corrupted file will be replicated on all of the other drives and the damage will become long term. Many commonly used file systems either don't feature real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a common matter on internet hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Website Hosting

In case you host your websites in a website hosting account with our company, you do not need to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform works with the advanced ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All the info that you upload will be stored in a RAID i.e. simultaneously on a large number of SSDs. All the file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file will not be corrupted. This could happen throughout the writing process on any drive and then a bad copy can 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 drives live and in case a corrupted file is identified, it's replaced with a good copy with the correct checksum from another 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

We've avoided any probability of files getting damaged silently because the servers where your semi-dedicated server account will be created employ a powerful file system known as ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we store all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. When there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that it happens right away, there is no chance that a damaged copy can remain on our web hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems employ this type of checks and what's more, even during a file system check following a sudden power failure, none of them will identify silently corrupted files. In comparison, ZFS does not crash after a power loss and the constant checksum monitoring makes a time-consuming file system check unnecessary.
