Data corruption is the accidental change of a file or the losing of information that often occurs during reading or writing. The reason may be hardware or software failure, and due to this fact, a file may become partially or completely corrupted, so it'll no longer function properly because its bits will be scrambled or lost. An image file, for example, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. If this kind of an issue appears and it isn't found by the system or by an admin, the data will get corrupted silently and if this happens on a drive which is a part of a RAID array where the information is synced between various different drives, the corrupted file shall be reproduced on all of the other drives and the harm will be permanent. Numerous frequently used file systems either don't feature real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where large volumes of information are stored.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting account will be guaranteed by the ZFS file system which we make use of on our cloud platform. Most hosting suppliers, including our firm, use multiple HDDs to keep content and since the drives work in a RAID, the same data is synchronized between the drives all of the time. In case a file on a drive is corrupted for reasons unknown, yet, it is very likely that it will be reproduced on the other drives since alternative file systems don't feature special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy shall be substituted with a good one from a different hard disk drive. Since this happens immediately, there's no possibility for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting damaged silently since the servers where your semi-dedicated hosting account will be created use a powerful file system named ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. When there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there is no chance that a damaged copy can remain on our hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems work with such checks and furthermore, even during a file system check after a sudden power loss, none of them can identify silently corrupted files. In comparison, ZFS does not crash after a power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
