Data corruption is the unintentional change of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software failure, and due to this fact, a file can become partially or entirely corrupted, so it will no longer function as it should because its bits shall be scrambled or missing. 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 since its content will be unreadable, etcetera. In case this kind of a problem appears and it's not recognized by the system or by an administrator, the data will become corrupted silently and if this happens on a drive that is a part of a RAID array where the information is synced between different drives, the corrupted file will be copied on all other drives and the damage will become long term. A large number of frequently used file systems either don't have real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where substantial volumes of info are stored.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your websites in a shared hosting account with our firm, you won't need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the cutting-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. All the information that you upload will be stored in a RAID i.e. simultaneously on multiple SSD drives. All of the file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file won't be corrupted. This could occur at the time of the writing process on any drive and then a damaged copy can be copied on the rest of the drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives in real time and in the event that a corrupted file is discovered, it is replaced with a good copy with the correct checksum from another drive. In this way, your information will remain undamaged no matter what, even if a whole drive fails.
