Data corruption is the accidental change of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software fail, and consequently, a file could become partially or entirely corrupted, so it will no longer function correctly since its bits will be scrambled or lost. An image file, for instance, will no longer present a true image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In the event that this kind of a problem occurs and it's not noticed by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the data is synchronized between different drives, the corrupted file shall be duplicated on all the other drives and the damage will be permanent. Numerous widely used file systems either don't feature real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a common problem on hosting servers where substantial volumes of info are kept.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the info uploaded in any shared hosting account that is created on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for each file. We will store your data on a large number of SSD drives which operate in a RAID, so the exact same files will be present on several places concurrently. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file differs from what it has to be, the file system replaces that file with a healthy version from a different drive in the RAID. There's no other file system which uses checksums, so it is possible for data to become silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not experience any kind of silent data corruption issues should you buy one of our semi-dedicated hosting packages as the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee 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 kept on a server. Since we store all content on a number of drives simultaneously, 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 should 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 drives. ZFS is the only file system you will find which uses checksums, which makes it far superior to other file systems which cannot identify silent data corruption and copy bad files across drives.
