Data corruption is the accidental modification of a file or the losing of information which often occurs during reading or writing. The reason can be hardware or software malfunction, and because of this, a file may become partially or completely corrupted, so it'll no longer work properly as its bits shall be scrambled or missing. An image file, for instance, will no longer show a true image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In the event that such a problem appears and it's not found by the system or by an admin, the data will get corrupted silently and in case this happens on a disk drive that is a part of a RAID array where the info is synced between different drives, the corrupted file will be duplicated on all other drives and the harm will be permanent. Many commonly used file systems either do not 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 very common matter on internet hosting servers where substantial amounts of information are kept.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account shall be ensured by the ZFS file system which we work with on our cloud platform. Most of the internet hosting suppliers, like our firm, use multiple HDDs to keep content and considering that the drives work in a RAID, identical data is synchronized between the drives all of the time. In case a file on a drive gets damaged for reasons unknown, yet, it is likely that it will be copied on the other drives because other file systems do not offer special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy will be replaced with a good one from a different disk drive. Because this happens immediately, there is no risk for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't encounter any silent data corruption issues whatsoever should you get one of our semi-dedicated server packages since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all of the files are undamaged all of 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 uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. 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 without delay, avoiding any probability of the bad copy to be synchronized on the remaining drives. ZFS is the only file system you will find that uses checksums, which makes it much more dependable than other file systems that are unable to detect silent data corruption and duplicate bad files across drives.
