Data corruption is the unintentional modification of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software fail, and because of this, a file could become partially or entirely corrupted, so it'll no longer work correctly since its bits will be scrambled or lost. An image file, for instance, 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, etcetera. When this kind of an issue occurs and it isn't found by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the information is synchronized between various different drives, the corrupted file will be replicated on all the other drives and the damage will become permanent. A number of frequently used file systems either do not feature real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where substantial volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your websites in a cloud hosting account from our firm, you won't have to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any data that you upload will be kept in a RAID i.e. simultaneously on many NVMes. All the file systems synchronize the files between the separate drives with this kind of a setup, but there's no real guarantee that a file won't be corrupted. This can occur at the time of the writing process on each drive and afterwards a bad copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all drives live and if a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. In this way, your info will remain unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers work with the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it will be stored on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all disks. All of the copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, so if it discovers a mismatch, that will indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other disks. Even if there is an unforeseen power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some failure, extending the time needed for the server to return online. ZFS is the file system that can truly protect your content from silent data corruption.
