Data corruption is the unintended transformation of a file or the loss of information that usually occurs during reading or writing. The reason could be hardware or software malfunction, and due to this fact, a file could become partially or fully corrupted, so it will no longer work correctly because its bits will be scrambled or lacking. An image file, for instance, will no longer present an authentic 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 case such an issue occurs and it's not noticed by the system or by an admin, the data will become corrupted silently and when this happens on a drive that's a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be duplicated on all the other drives and the harm will be permanent. A number of popular file systems either don't offer real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common problem on internet hosting servers where large volumes of information are kept.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the info uploaded in any cloud hosting
account which is created on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption through a unique checksum for each file. We shall store your information on multiple SSD drives which work in a RAID, so identical files will be present on several places concurrently. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from a different drive in 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 replicated on all drives with time, but since that can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't need to deal with any silent data corruption issues should you get one of our semi-dedicated hosting
solutions due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to make sure that all the files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. As 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 in real time. If 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 right away, avoiding any possibility of the bad copy to be synchronized on the other hard disks. ZFS is the sole file system available on the market that uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and copy bad files across hard drives.
