Data corruption is the unintentional change of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it'll no longer work as it should as its bits shall be scrambled or missing. An image file, for instance, will no longer display an authentic 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 an issue appears and it's not recognized by the system or by an administrator, the data will become corrupted silently and if this happens on a drive that is a part of a RAID array where the information is synchronized between different drives, the corrupted file will be duplicated on all other drives and the damage will be long term. Many popular file systems either don't have real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a common issue on web hosting servers where large amounts of info are stored.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the data uploaded in each and every shared hosting account which is created on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption via a unique checksum for each and every file. We will store your data on a large number of SSD drives that function in a RAID, so identical files will be present on several places at the same time. ZFS checks the digital fingerprint of all files on all of the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy version from some other drive in the RAID. There's no other file system which uses checksums, so it's possible for data to be silently damaged 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 worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any risk of files getting corrupted silently because the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we save all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. In case there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since this happens in real time, there is no chance that a corrupted copy could remain on our servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with this type of checks and what's more, even during a file system check following an unexpected power loss, none of them can discover silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the regular checksum monitoring makes a lenghty file system check unneeded.
