Data corruption is the unintended change of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software failure, and consequently, a file may become partially or fully corrupted, so it'll no longer work as it should as its bits shall be scrambled or lost. An image file, for example, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In the event that this kind of an issue appears and it's not found by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive which is part of a RAID array where the info is synced between various different drives, the corrupted file will be copied on all the other drives and the harm will be long term. A large number of commonly used file systems either do not offer real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where large volumes of data are stored.

No Data Corruption & Data Integrity in Cloud Web Hosting

If you host your websites in a cloud web hosting account with our company, you don't have to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be stored in a RAID i.e. simultaneously on many different SSDs. Many file systems synchronize the files between the separate drives with this type of a setup, but there is no real guarantee that a file won't get corrupted. This could happen throughout the writing process on any drive and afterwards a corrupted copy can be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all drives right away and in case a corrupted file is identified, it's swapped with a good copy with the correct checksum from some other drive. By doing this, your info will stay unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't encounter any kind of silent data corruption issues whatsoever in case you acquire one of our semi-dedicated server packages because the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all of your files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Due to the fact that we store all content on multiple drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any possibility of the bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system available on the market that uses checksums, which makes it far superior to other file systems which are unable to identify silent data corruption and copy bad files across hard drives.
