Data corruption is the unintended transformation of a file or the loss of information that usually occurs during reading or writing. The reason could be hardware or software failure, and because of this, a file could become partially or entirely corrupted, so it will no longer work correctly since its bits will be scrambled or lost. An image file, for instance, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In the event that such a problem occurs and it is not identified by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that's a part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be duplicated on all of the other drives and the harm will become permanent. A number of popular file systems either do not have real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a very common problem on internet hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the information uploaded in each and every shared hosting account which is made on our cloud platform since we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each file. We shall store your data on multiple NVMe drives which work in a RAID, so the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy version from a different drive within the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't encounter any kind of silent data corruption issues whatsoever in case you obtain one of our semi-dedicated server plans as the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all the files are intact all the time. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Due to the fact that we store all content on multiple drives at the same time, the same file uses the same checksum on all of the 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 right away, avoiding any probability of the damaged copy to be synchronized on the other hard disks. ZFS is the sole file system available on the market which uses checksums, which makes it much more reliable than other file systems that cannot identify silent data corruption and duplicate bad files across hard drives.
