Data corruption is the accidental transformation of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software malfunction, and as a consequence, a file can become partially or completely corrupted, so it will no longer work properly since its bits will be scrambled or missing. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When such an issue appears and it isn't identified by the system or by an admin, the data will get corrupted silently and if this happens on a drive which is a part of a RAID array where the info is synchronized between different drives, the corrupted file shall be replicated on all of the other drives and the damage will be permanent. A number of frequently used file systems either do not feature real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Shared Hosting

We have resolved the problem of silent data corruption on all of our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one out there that checks all of the files immediately by employing a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and continually synchronized between them for redundancy. ZFS constantly examines the checksum of all files and in case any file is detected as damaged, it's replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the rest of the SSDs. ZFS requires a lot of physical memory in order to carry out the real-time checks and the advantage of our cloud web hosting platform is that we use multiple powerful servers working together. In case you host your sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't experience any kind of silent data corruption issues whatsoever in case you acquire one of our semi-dedicated hosting plans as the ZFS file system that we work with on our cloud hosting platform uses checksums to ensure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. Because 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. If 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 probability of the bad copy to be synchronized on the remaining drives. ZFS is the sole file system you will find that uses checksums, which makes it far superior to other file systems which are not able to identify silent data corruption and copy bad files across hard drives.
