Data corruption is the unintended modification of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file may become partially or fully corrupted, so it will no longer function properly because its bits shall be scrambled or missing. An image file, for example, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In the event that such an issue appears and it is not recognized by the system or by an administrator, the data will get corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be duplicated on all of the other drives and the harm will be long term. A number of commonly used file systems either do not feature real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a rather common matter on web hosting servers where substantial volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your websites in a cloud hosting account with our firm, you do not have to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. All of the information that you upload will be stored in a RAID i.e. simultaneously on multiple NVMe drives. All the file systems synchronize the files between the different drives using this kind of a setup, but there's no real guarantee that a file will not get corrupted. This can happen at the time of the writing process on each drive and after that a corrupted copy can be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives live and in case 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 won't have to deal with any silent data corruption issues in case you get one of our semi-dedicated server plans due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all of the files are intact at all times. A checksum is a unique digital fingerprint that is given to each and every file saved on a server. Because we store all content on a number of drives simultaneously, the same file has 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. In the event that 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 corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system out there which uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and copy bad files across drives.
