Data corruption is the accidental change of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software failure, and as a result, a file could become partially or entirely corrupted, so it'll no longer function correctly because its bits will be scrambled or lost. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If this kind of a problem appears and it isn't identified by the system or by an administrator, the data will be corrupted silently and when this happens on a drive which is a part of a RAID array where the information is synchronized between different drives, the corrupted file shall be copied on all other drives and the harm will be long term. Many widely used file systems either do not feature real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where huge amounts of information are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your sites in a shared website hosting account with our firm, you won't need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. All of the information that you upload will be saved in a RAID i.e. simultaneously on a number of SSDs. All the file systems synchronize the files between the separate drives with this type of a setup, but there's no real guarantee that a file won't get corrupted. This may occur throughout the writing process on each drive and after that a damaged copy can be copied on the other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives immediately and when a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not encounter any kind of silent data corruption issues whatsoever should you buy one of our semi-dedicated hosting solutions since the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all of the files are undamaged all the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Due to the fact that we store all content on multiple 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 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 possibility of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the only file system out there which uses checksums, which makes it much more dependable than other file systems which cannot identify silent data corruption and duplicate bad files across hard drives.
