Data corruption is the accidental transformation of a file or the losing of information which often occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file can become partially or fully corrupted, so it will no longer work as it should because its bits will be scrambled or missing. An image file, for example, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. When this kind of a problem appears and it is 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 information is synchronized between different drives, the corrupted file will be replicated on all the other drives and the harm will become permanent. A number of commonly used file systems either do not offer real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common problem on web hosting servers where substantial amounts of data are stored.

No Data Corruption & Data Integrity in Hosting

In case you host your websites in a hosting account from our firm, you do not 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 amazing ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. Many file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file won't be corrupted. This can happen throughout the writing process on each drive and after that a damaged copy may be copied on the 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 located, it is swapped with a good copy with the correct checksum from another drive. This way, your info will stay unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption as all of our storage servers employ the advanced ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to verify the integrity of every single file. When you upload content to your account, it will be stored on several redundant drives in a RAID i.e. the files will be the same across all disks. All the copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, which would indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other disks. Even if there is a sudden power failure, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform after some malfunction, lengthening the time needed for the server to get back online. ZFS is the only file system which can really protect your content from silent data corruption.
