Data corruption is the unintended modification of a file or the losing of information that usually occurs during reading or writing. The reason can be hardware or software fail, and due to this fact, a file can become partially or completely corrupted, so it will no longer work properly since its bits will be scrambled or lacking. An image file, for instance, will no longer display a real 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. When this kind of an issue appears and it is not noticed by the system or by an admin, the data will be corrupted silently and when this happens on a drive that's a part of a RAID array where the information is synchronized between different drives, the corrupted file will be duplicated on all the other drives and the harm will become long term. Many frequently used file systems either don't offer real-time checks or do not have good ones that can detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where large volumes of info are stored.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your websites in a shared hosting account with our firm, you won't need to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be stored in a RAID i.e. simultaneously on multiple NVMes. All of 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 will not get corrupted. This may happen during the writing process on each drive and then a corrupted copy may 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 of the drives in real time and when a corrupted file is found, it's swapped with a good copy with the correct checksum from some other drive. By doing this, your information will remain intact 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 resistant to silent data corruption because all our storage servers use the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of every single file. When you upload content to your account, it will be kept on several redundant drives operating in a RAID i.e. the files shall be the same on all disks. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, that will indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other drives. Even if there's an unforeseen blackout, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, prolonging the time needed for the server to get back online. ZFS is the file system which can really protect your content from silent data corruption.
