Data corruption is the accidental modification of a file or the losing of information that often occurs during reading or writing. The reason can be hardware or software fail, and as a result, a file could become partially or entirely corrupted, so it will no longer function properly as its bits shall be scrambled or lacking. An image file, for example, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When such a problem appears and it's not noticed by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive which is a part of a RAID array where the information is synced between various different drives, the corrupted file will be duplicated on all of the other drives and the harm will be long term. A number of frequently used file systems either don't have 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 issue on web hosting servers where large amounts of info are kept.

No Data Corruption & Data Integrity in Web Hosting

If you host your websites in a web hosting account with our company, you won't need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be stored in a RAID i.e. simultaneously on a number of SSDs. Many file systems synchronize the files between the separate drives using this kind of a setup, but there's no real warranty that a file will not be corrupted. This can happen at the time of the writing process on each drive and after that a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives instantly and in case a corrupted file is discovered, it is replaced with a good copy with the correct checksum from another drive. In this way, your data will continue to be 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 since all our storage servers employ the effective ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to guarantee the integrity of every single file. When you upload content to your account, it'll be saved on several redundant drives employed in a RAID i.e. the files will be the same on all drives. All copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it finds a mismatch, which would indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some breakdown, lengthening the time needed for the server to go back online. ZFS is the file system which can really protect your content from silent data corruption.
