Data corruption is the accidental modification of a file or the loss of info that usually occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file may become partially or completely corrupted, so it will no longer work correctly since its bits will be scrambled or lost. An image file, for example, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case this kind of a problem occurs and it is not found by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that's a part of a RAID array where the data is synced between various drives, the corrupted file shall be duplicated on all other drives and the harm will be permanent. Many popular file systems either do not offer real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a very common problem on hosting servers where substantial volumes of information are stored.

No Data Corruption & Data Integrity in Website Hosting

If you host your Internet sites in a website hosting account from our firm, you don't need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All the information that you upload will be saved in a RAID i.e. simultaneously on a large number of SSD drives. All the file systems synchronize the files between the different drives using such a setup, but there is no real warranty that a file won't get corrupted. This could happen at the time of the writing process on any drive and afterwards a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all of the drives immediately and if a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. That way, your data will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any silent data corruption issues if you buy one of our semi-dedicated server plans since the ZFS file system that we work with on our cloud hosting platform uses checksums to make sure that all of the files are undamaged all of the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Since we store all content on a number of drives at the same time, 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 right away. In case 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 possibility of the corrupted copy to be synchronized on the other hard drives. ZFS is the sole file system out there that uses checksums, which makes it much more reliable than other file systems that are not able to identify silent data corruption and copy bad files across drives.
