Data corruption is the unintended change of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software failure, and consequently, a file could become partially or completely corrupted, so it'll no longer work correctly as its bits shall be scrambled or lacking. An image file, for instance, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When this kind of an issue appears and it isn't found by the system or by an admin, the data will get corrupted silently and if this happens on a drive which is part of a RAID array where the data is synced between various drives, the corrupted file will be copied on all other drives and the harm will be permanent. A large number of commonly used file systems either do not feature real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where huge volumes of data are stored.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your sites in a shared hosting account from our firm, you don't have to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform works with the reliable ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. A lot of file systems synchronize the files between the separate drives with this type of a setup, but there's no real warranty that a file will not get corrupted. This could happen throughout the writing process on any drive and after that a bad copy can be copied on the other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all of the drives live and when a corrupted file is found, it's swapped with a good copy with the correct checksum from another drive. That way, your information will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any risk of files getting corrupted silently since the servers where your semi-dedicated server account will be created take advantage of a powerful file system named ZFS. Its main advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In case there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and since this happens in real time, there's no chance that a corrupted copy could remain on our servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems employ such checks and furthermore, even during a file system check right after a sudden blackout, none of them will discover silently corrupted files. In contrast, ZFS will not crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check unneeded.
