Data corruption is the accidental change of a file or the loss of information which often occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file could become partially or entirely corrupted, so it will no longer work properly because its bits shall be scrambled or lacking. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If this kind of an issue occurs and it isn't found by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive that is a part of a RAID array where the information is synced between different drives, the corrupted file will be reproduced on all other drives and the damage will be permanent. Numerous popular file systems either do not have real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where large volumes of data are kept.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your websites in a shared hosting account from our company, you don't need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the amazing 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 saved in a RAID i.e. simultaneously on a number of SSDs. All file systems synchronize the files between the different drives using this type of a setup, but there is no real guarantee that a file won't get corrupted. This could occur throughout the writing process on each drive and after that a bad copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives in real time and in case a corrupted file is found, it is swapped with a good copy with the correct checksum from another drive. In this way, your information will remain unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't have to deal with any kind of silent data corruption issues if you get one of our semi-dedicated server solutions due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to guarantee that all files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. As we store all content on a number of drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any possibility of the corrupted copy to be synchronized on the remaining hard drives. ZFS is the only file system on the market that uses checksums, which makes it much more reliable than other file systems that cannot identify silent data corruption and copy bad files across drives.
