Data corruption is the unintended change of a file or the losing of info which usually occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file could become partially or entirely corrupted, so it will no longer function as it should as its bits shall be scrambled or lost. An image file, for example, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If this kind of an issue occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that is a part of a RAID array where the data is synced between various drives, the corrupted file shall be replicated on all of the other drives and the damage will be permanent. A large number of widespread file systems either do not offer real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a very common problem on internet hosting servers where substantial volumes of data are kept.

No Data Corruption & Data Integrity in Web Hosting

We've dealt with the matter of silent data corruption on all of our web hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems because it is the only one out there that checks all the files immediately by using a checksum - a digital identifier which is unique for each file. When you upload content to your account, it will be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS constantly examines the checksum of all files and in the event that any file is detected as damaged, it is replaced quickly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the other SSDs. ZFS needs lots of physical memory to execute the real-time checks and the benefit 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 need to deal with any silent data corruption issues whatsoever in case you buy one of our semi-dedicated server plans because the ZFS file system that we use on our cloud hosting platform uses checksums in order to guarantee that all files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. As 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. In case 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 rest of the hard drives. ZFS is the sole file system you will find which uses checksums, which makes it much more dependable than other file systems that cannot detect silent data corruption and copy bad files across hard drives.
