Data corruption is the unintentional modification of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software failure, and because of this, a file can become partially or completely corrupted, so it will no longer function properly since its bits will be scrambled or lacking. An image file, for instance, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case this kind of an issue appears and it isn't found by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive that is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be reproduced on all other drives and the harm will become permanent. A number of widely used file systems either don't offer real-time checks or do not have high quality ones which can detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where huge amounts of info are kept.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the information uploaded in each and every cloud hosting account which is generated on our cloud platform since we employ the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption through a unique checksum for each and every file. We'll store your information on a large number of NVMe drives which operate in a RAID, so identical files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with a healthy version from some other drive within the RAID. There's no other file system which uses checksums, so it's easy for data to become silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't encounter any kind of silent data corruption issues whatsoever if you acquire one of our semi-dedicated hosting plans due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all files are undamaged all the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. As we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In case 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 damaged copy to be synchronized on the other drives. ZFS is the only file system you will find that uses checksums, which makes it far superior to other file systems that are unable to identify silent data corruption and duplicate bad files across hard drives.
