Data corruption is the unintentional modification of a file or the losing of info which usually occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file may become partially or entirely corrupted, so it'll no longer function as it should since its bits will be scrambled or lacking. An image file, for example, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. If this kind of a problem occurs and it's not identified by the system or by an admin, the data will get corrupted silently and when this happens on a drive that's part of a RAID array where the data is synchronized between various drives, the corrupted file shall be replicated on all of the other drives and the damage will be permanent. A number of popular file systems either don't feature 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 rather common issue on hosting servers where substantial volumes of data are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the info uploaded in any cloud website hosting
account that is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption through a unique checksum for each and every file. We will store your info on a number of SSD drives which work in a RAID, so the same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with a healthy copy from another drive in the RAID. There's no other file system which uses checksums, so it is possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server using 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 need to deal with any silent data corruption issues should you get one of our semi-dedicated hosting
plans as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all files are undamaged all of the time. A checksum is a unique digital fingerprint that is given to each and every file kept on a server. Because we store all content on a number of drives at the same time, the same file has 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 probability of the bad copy to be synchronized on the remaining hard disks. ZFS is the sole file system you can find that uses checksums, which makes it much more dependable than other file systems which are not able to identify silent data corruption and duplicate bad files across hard drives.
