Data corruption is the accidental modification of a file or the losing of information which usually occurs during reading or writing. The reason could be hardware or software fail, and consequently, a file can become partially or completely corrupted, so it will no longer function as it should since its bits shall be scrambled or missing. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In case such an issue appears and it is not found by the system or by an administrator, the data will get corrupted silently and if this happens on a drive which is part of a RAID array where the information is synchronized between different drives, the corrupted file shall be replicated on all the other drives and the harm will become long term. Numerous widespread file systems either don't offer real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a common problem on hosting servers where huge amounts of info are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your websites in a cloud website hosting
account from our company, you won't have to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the reliable ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All data that you upload will be stored in a RAID i.e. simultaneously on multiple SSDs. All of the file systems synchronize the files between the separate drives using such a setup, but there is no real guarantee that a file won't get corrupted. This could occur throughout the writing process on any drive and after that a bad copy may be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all of the drives in real time and when a corrupted file is discovered, it is substituted 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 Hosting
You will not need to deal with any silent data corruption issues in case you purchase one of our semi-dedicated hosting
plans due to the fact that the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all of the files are undamaged all the time. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 chance of the damaged copy to be synchronized on the remaining hard disks. ZFS is the only file system on the market which uses checksums, which makes it far superior to other file systems that are not able to detect silent data corruption and copy bad files across drives.
