Data corruption is the unintentional modification of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file could become partially or fully corrupted, so it'll no longer function as it should because its bits shall be scrambled or missing. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. In the event that such a problem appears and it's not noticed by the system or by an admin, the data will be corrupted silently and when this happens on a drive which is a part of a RAID array where the information is synchronized between different drives, the corrupted file will be duplicated on all of the other drives and the harm will become long term. Numerous popular file systems either don't 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 very common matter on web hosting servers where substantial volumes of info are kept.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the info uploaded in every single cloud hosting account that is created on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption thanks to a unique checksum for each and every file. We'll store your data on multiple SSD drives which work in a RAID, so exactly the same files will be present on several places at once. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with an undamaged version from a different drive within the RAID. There's no other file system that uses checksums, so it is easy for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not encounter any kind of silent data corruption issues if you purchase one of our semi-dedicated server plans since the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is given 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 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 possibility of the corrupted copy to be synchronized on the remaining hard disks. ZFS is the only file system you can find that uses checksums, which makes it far superior to other file systems which are not able to detect silent data corruption and copy bad files across drives.
