Data corruption is the accidental transformation of a file or the losing of information that often occurs during reading or writing. The reason could be hardware or software fail, and as a consequence, 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 example, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. If such a problem appears and it isn't noticed by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that's part of a RAID array where the info is synchronized between different drives, the corrupted file shall be replicated on all other drives and the harm will be permanent. Numerous widespread file systems either do not 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 very common problem on web hosting servers where large volumes of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your websites in a shared hosting account from our firm, you don't have to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform uses the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. All of the data that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. All the file systems synchronize the files between the different drives using this type of a setup, but there is no real warranty that a file will not get corrupted. This could occur throughout the writing process on any drive and after that a damaged copy may be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives immediately and in case a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. By doing this, your info will continue to be unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not encounter any silent data corruption issues should you acquire one of our semi-dedicated hosting solutions as the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all of the files are intact all of the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. Since we store all content on a number of drives simultaneously, 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. 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 without delay, avoiding any probability of the bad copy to be synchronized on the rest of the hard drives. ZFS is the only file system you can get that uses checksums, which makes it far superior to other file systems which are not able to identify silent data corruption and duplicate bad files across drives.
