Data corruption is the accidental modification of a file or the losing of information which often occurs during reading or writing. The reason could be hardware or software malfunction, and as a result, a file can become partially or entirely corrupted, so it'll no longer function properly since its bits will be scrambled or lacking. An image file, for example, will no longer present an actual image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. When this kind of a problem occurs and it isn't identified by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive which is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be copied on all the other drives and the harm will be permanent. A large number of widespread file systems either do not have real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a rather common problem on hosting servers where substantial volumes of information are kept.
No Data Corruption & Data Integrity in Cloud Web Hosting
We warrant the integrity of the information uploaded in every cloud web hosting
account that is created on our cloud platform as we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for every single file. We'll store your info on multiple SSD drives that operate in a RAID, so the exact same files will exist on several places concurrently. 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 should be, the file system replaces that file with a healthy version from some other drive in the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be reproduced on all drives with time, but since that 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 will not experience any kind of silent data corruption issues whatsoever if you acquire one of our semi-dedicated hosting
solutions due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all of your files are intact at all times. A checksum is a unique digital fingerprint that is given to each and every file saved on a server. Due to the fact that we store all content on a number of drives at the same time, the same file uses the same checksum on all of 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 chance of the bad copy to be synchronized on the remaining hard disks. ZFS is the only file system you can find which uses checksums, which makes it far superior to other file systems which are not able to identify silent data corruption and duplicate bad files across hard drives.
