Data corruption is the accidental change of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software fail, and as a consequence, a file could become partially or completely corrupted, so it'll no longer function as it should because its bits shall be scrambled or lacking. An image file, for example, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When such an issue appears and it's not identified by the system or by an administrator, the data will be corrupted silently and in case this happens on a drive that is part of a RAID array where the info is synchronized between various different drives, the corrupted file will be replicated on all other drives and the harm will become permanent. A large number of widespread file systems either do not have real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common problem on hosting servers where large volumes of info are stored.

No Data Corruption & Data Integrity in Website Hosting

In case you host your Internet sites in a website hosting account with our company, you don't need to worry about your data ever getting damaged. We can ensure that because our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any data that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. All the file systems synchronize the files between the different drives with this kind of a setup, but there is no real warranty that a file will not get corrupted. This can happen throughout the writing process on each drive and after that a damaged copy may be copied on the other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives right away and in the event that a corrupted file is found, it's replaced with a good copy with the correct checksum from another 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 Hosting

We've avoided any chance of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. As we store all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. In the event that there's a mismatch, the bad copy is replaced with a good one from one of the other drives and because it happens right away, there is no chance that a corrupted copy can remain on our website hosting servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems work with this kind of checks and in addition, even during a file system check after an unexpected blackout, none of them will discover silently corrupted files. In comparison, ZFS will not crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unnecessary.
