Data corruption is the accidental change of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software failure, and as a result, a file can become partially or completely corrupted, so it'll no longer work correctly as its bits shall be scrambled or lost. 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 since its content will be unreadable, etc. In the event that such an issue occurs and it's not found by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that's part of a RAID array where the info is synced between different drives, the corrupted file shall be duplicated on all the other drives and the harm will be long term. A number of widely used file systems either don't 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 rather common issue on web hosting servers where large volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

If you host your Internet sites in a cloud website hosting account with our firm, you won't have to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform works with the leading-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any data that you upload will be stored in a RAID i.e. simultaneously on numerous NVMes. All the file systems synchronize the files between the different drives using such a setup, but there's no real warranty that a file won't get corrupted. This can occur at the time of the writing process on any drive and afterwards a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all the drives live and in case a corrupted file is discovered, it is swapped with a good copy with the correct checksum from some other drive. This way, your information will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption since all of our storage servers employ the efficient ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it will be saved on several redundant drives employed in a RAID i.e. the files shall be the same on all disks. All copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, so if it discovers a mismatch, that will indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other drives. Even if there is an unexpected power failure, 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 after some breakdown, extending the time needed for the server to return online. ZFS is the only file system that can really protect your content from silent data corruption.
