Data corruption is the unintended modification of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software malfunction, and as a result, a file could become partially or fully corrupted, so it'll no longer function correctly because its bits shall be scrambled or missing. An image file, for instance, will no longer present a true image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. When this kind of a problem occurs and it's not recognized by the system or by an admin, the data will become corrupted silently and if this happens on a drive which is part of a RAID array where the data is synchronized between different drives, the corrupted file shall be reproduced on all other drives and the harm will be permanent. Numerous popular file systems either don't offer real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common issue on hosting servers where huge volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

In case you host your Internet sites in a cloud website hosting account from our company, you don't have to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. All of the info that you upload will be saved in a RAID i.e. simultaneously on many different SSDs. Many file systems synchronize the files between the different drives with such a setup, but there is no real guarantee that a file will not be corrupted. This may occur during the writing process on each drive and then a corrupted copy may be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives in real time and in case a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. In this way, your data will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any kind of silent data corruption issues should you obtain one of our semi-dedicated server plans since the ZFS file system that we work with on our cloud hosting platform uses checksums in order to ensure that all files are intact all the time. A checksum is a unique digital fingerprint that is given to each and every file kept on a server. Since we store all content on multiple drives simultaneously, 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 without delay, avoiding any probability of the corrupted copy to be synchronized on the other hard drives. ZFS is the sole file system you can find which uses checksums, which makes it much more reliable than other file systems which are not able to detect silent data corruption and duplicate bad files across drives.
