Data corruption is the unintended transformation of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software failure, and for that reason, a file could become partially or entirely corrupted, so it'll no longer work properly as its bits will be scrambled or missing. An image file, for example, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case such an issue occurs and it's not found by the system or by an admin, the data will get corrupted silently and if 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 will be duplicated on all the other drives and the damage will be permanent. A large number of popular file systems either don't feature 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 matter on internet hosting servers where large volumes of info are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

We have tackled the issue of silent data corruption on our cloud website hosting servers by using the leading-edge Z file system, or ZFS. The latter is better than other file systems as it is the only one on the market which checks all of the files immediately by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several SSD 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's replaced quickly with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the other SSDs. ZFS requires plenty of physical memory to execute the real-time checks and the advantage of our cloud hosting platform is that we work with multiple powerful servers working together. If you host your Internet sites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't encounter any kind of silent data corruption issues whatsoever should you acquire one of our semi-dedicated server plans because the ZFS file system that we employ on our cloud hosting platform uses checksums to make sure that all of the files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Because we store all content on multiple drives simultaneously, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 rest of the drives. ZFS is the sole file system you can find that uses checksums, which makes it far superior to other file systems which cannot identify silent data corruption and duplicate bad files across drives.
