Data corruption is the unintended change of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file could become partially or entirely corrupted, so it'll no longer function properly since its bits will be scrambled or missing. 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 for the reason that its content will be unreadable, etcetera. In case such a problem occurs and it isn't recognized by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive that is a part of a RAID array where the info is synced between various different drives, the corrupted file shall be replicated on all the other drives and the harm will be permanent. Many frequently used file systems either don't offer real-time checks or don't have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where large amounts of data are kept.

No Data Corruption & Data Integrity in Shared Hosting

We've resolved the problem of silent data corruption on all our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems because it is the only one in existence that checks all files right away by using a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and regularly synchronized between them for redundancy. ZFS constantly compares the checksum of all files and in the event that any file is detected as damaged, it is replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be copied on the other NVMes. ZFS requires plenty of physical memory in order to perform the real-time checks and the benefit of our cloud web hosting platform is that we employ multiple powerful servers working together. If you host your Internet sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't encounter any silent data corruption issues in case you purchase one of our semi-dedicated hosting packages since the ZFS file system that we employ 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 which is given to each and every file saved on a server. Due to the fact that we store all content on a number of drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 right away, avoiding any possibility of the corrupted copy to be synchronized on the other hard disks. ZFS is the only file system out there that uses checksums, which makes it far superior to other file systems that are unable to identify silent data corruption and copy bad files across drives.
