Data corruption is the accidental change of a file or the losing of information which often occurs during reading or writing. The reason may be hardware or software malfunction, and due to this fact, a file may become partially or completely corrupted, so it will no longer function as it should since its bits shall be scrambled or lacking. An image file, for instance, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. When this kind of a problem appears and it's not recognized by the system or by an admin, the data will get corrupted silently and if this happens on a drive that's part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be copied on all of the other drives and the harm will be permanent. A number of widespread file systems either don't offer real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most hosting providers, including our company, use multiple hard disk drives to store content and because the drives work in a RAID, identical information is synchronized between the drives all of the time. In case a file on a drive gets damaged for whatever reason, however, it is likely that it will be duplicated on the other drives since alternative file systems don't have special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be swapped with a good one from another hard disk drive. Due to the fact that this happens right away, there is no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any risk of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we save all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. In the event that there's a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that this happens in real time, there's no chance that a corrupted copy can remain on our servers or that it could be duplicated to the other drives in the RAID. None of the other file systems work with this kind of checks and furthermore, even during a file system check right after an unexpected power failure, none of them will find silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the continual checksum monitoring makes a time-consuming file system check obsolete.
