Data corruption is the accidental modification of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software fail, and as a consequence, a file can become partially or fully corrupted, so it'll no longer work correctly because its bits shall be scrambled or lost. An image file, for instance, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In case this kind of an issue appears and it isn't recognized by the system or by an admin, the data will be corrupted silently and if this happens on a drive that's part of a RAID array where the info is synchronized between various different drives, the corrupted file will be duplicated on all of the other drives and the damage will be permanent. Many popular file systems either do not feature real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your sites in a shared website hosting account with our firm, you won't have to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All the data that you upload will be stored in a RAID i.e. simultaneously on a number of SSDs. All the file systems synchronize the files between the different drives using this kind of a setup, but there is no real guarantee that a file won't get corrupted. This could occur at the time of the writing process on any drive and afterwards a corrupted copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives right away and in case a corrupted file is identified, it's substituted with a good copy with the correct checksum from another drive. In this way, 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 risk of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created use a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we save all content on numerous 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. When there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because it happens right away, there's no chance that a corrupted copy could remain on our servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and what is more, even during a file system check after a sudden power loss, none of them will identify silently corrupted files. In comparison, ZFS does not crash after a blackout and the constant checksum monitoring makes a time-consuming file system check unneeded.
