Data corruption is the unintended change of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software failure, and as a result, a file may become partially or entirely corrupted, so it'll no longer function correctly as its bits will be scrambled or lost. An image file, for example, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. When such an issue appears and it is not identified 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 data is synced between various drives, the corrupted file will be duplicated on all of the other drives and the harm will become permanent. Many widespread file systems either don't feature real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common problem on web hosting servers where huge volumes of information are kept.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your sites in a cloud hosting account from our firm, you won't need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. All data that you upload will be kept in a RAID i.e. simultaneously on many different NVMe drives. All of the file systems synchronize the files between the different drives with such a setup, but there's no real warranty that a file won't be corrupted. This could occur at the time of the writing process on any drive and then a corrupted copy can be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all drives instantly and if a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. By doing this, your data will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you purchase one of our semi-dedicated server packages, you won't need to be concerned about silent data corruption since we use ZFS - an advanced file system that checks all of the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several NVMe drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no threat for any part of your content at any time. By comparison, all of the other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a bad copy may be replicated on the rest of the drives as well and you could lose critical info. Because this is not the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
