Data corruption is the unintentional transformation of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file may become partially or completely corrupted, so it'll no longer function properly because its bits will be scrambled or lost. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If this kind of a problem appears and it's not identified by the system or by an administrator, the data will become corrupted silently and in case this happens on a drive that is a part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be reproduced on all the other drives and the harm will be long term. A large number of frequently used file systems either don't have real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where huge volumes of info are kept.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the data uploaded in each and every website hosting
account which is made on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We will store your data on a number of SSD drives that work in a RAID, so exactly the same files will exist on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged version from some other drive in the RAID. There's no other file system that uses checksums, so it is possible for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't need to deal with any kind of silent data corruption issues whatsoever in case you get one of our semi-dedicated hosting
plans as the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all of your files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Because we store all content on multiple drives at the same time, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. 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 rest of the hard disks. ZFS is the sole file system you can find that uses checksums, which makes it far superior to other file systems which cannot detect silent data corruption and copy bad files across drives.
