Data corruption is the accidental transformation of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file could become partially or fully corrupted, so it'll no longer function correctly as its bits will be scrambled or lacking. An image file, for example, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In the event that this kind of a problem occurs and it isn't identified by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that's part of a RAID array where the info is synced between various different drives, the corrupted file shall be duplicated on all other drives and the damage will be permanent. A large number of widely used file systems either don't have real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where substantial amounts of information are kept.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the info uploaded in each shared hosting
account which is made on our cloud platform because we work with 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 shall store your information on multiple SSD drives which function in a RAID, so the same files will be present on several places at the same time. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in the event that the checksum of any file differs from what it should be, the file system swaps that file with a healthy version from some other drive from the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't need to deal with any kind of silent data corruption issues should you obtain one of our semi-dedicated server
solutions since the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all files are undamaged all the time. A checksum is a unique digital fingerprint which is allotted to each and every file saved on a server. As we store all content on multiple drives simultaneously, the same file uses the same checksum on all 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 without delay, avoiding any chance of the damaged copy to be synchronized on the remaining drives. ZFS is the sole file system you can find which uses checksums, which makes it much more dependable than other file systems which cannot identify silent data corruption and duplicate bad files across hard drives.
