Data corruption is the unintentional modification of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it'll no longer work as it should since its bits shall be scrambled or lost. An image file, for instance, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If such an issue appears and it isn't found by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive that is a part of a RAID array where the data is synchronized between different drives, the corrupted file will be duplicated on all of the other drives and the harm will become long term. Numerous widespread 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 very common matter on hosting servers where substantial volumes of info are kept.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your Internet sites in a shared hosting account with our firm, you will not have to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform works with the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All of the information that you upload will be kept in a RAID i.e. simultaneously on multiple SSD drives. All the file systems synchronize the files between the different drives using this type of a setup, but there is no real warranty that a file won't get corrupted. This could occur throughout the writing process on any drive and after that a corrupted copy can be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives immediately and in the event that a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. By doing this, your data will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system known as ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we keep all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because it happens instantly, there's no chance that a damaged copy can remain on our website hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems use this type of checks and in addition, even during a file system check following a sudden power failure, none of them can detect silently corrupted files. In contrast, ZFS won't crash after a power loss and the constant checksum monitoring makes a time-consuming file system check unneeded.
