Data corruption is the unintended transformation of a file or the losing of information that often occurs during reading or writing. The reason can be hardware or software malfunction, and because of this, a file can become partially or fully corrupted, so it will no longer work correctly because its bits shall be scrambled or lacking. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. If such an issue appears and it is not found by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive which is a part of a RAID array where the information is synced between different drives, the corrupted file shall be replicated on all the other drives and the harm will become long term. Many frequently used file systems either don't offer real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Web Hosting
If you host your sites in a cloud web hosting account with our company, you will not need to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform uses the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. All info that you upload will be stored in a RAID i.e. simultaneously on a large number of SSDs. All the file systems synchronize the files between the different drives using such a setup, but there's no real warranty that a file won't get corrupted. This can occur throughout the writing process on each drive and afterwards a corrupted copy may be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all drives live and in the event that a corrupted file is located, it's substituted with a good copy with the correct checksum from another drive. That way, your info will continue to be unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any kind of silent data corruption issues whatsoever in case you buy one of our semi-dedicated server packages due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to ensure that all files are intact at all times. A checksum is a unique digital fingerprint that is allotted to each and every file kept on a server. Due to the fact that we store all content on a number of 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 should be, it replaces that file with a healthy copy right away, avoiding any possibility of the corrupted copy to be synchronized on the remaining hard disks. ZFS is the only file system on the market which uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and copy bad files across hard drives.
