Data corruption is the unintended modification of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file could become partially or fully corrupted, so it'll no longer function as it should as its bits shall be scrambled or lost. An image file, for instance, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When such an issue occurs and it is not found by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive which is part of a RAID array where the information is synchronized between various different drives, the corrupted file will be copied on all other drives and the damage will become permanent. A large number of commonly used file systems either don't feature real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common issue on hosting servers where substantial amounts of info are kept.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account from our company, you will not need to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform works with the advanced 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 data that you upload will be kept in a RAID i.e. simultaneously on a large number of NVMe drives. A lot of file systems synchronize the files between the different drives using such a setup, but there is no real guarantee that a file will not get corrupted. This can happen throughout the writing process on any drive and after that a damaged 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 of the drives instantly and if a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. 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

If you purchase one of our semi-dedicated server plans, you will not have to worry about silent file corruption since we use ZFS - a high level file system which keeps track of all 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. That file will be synced between multiple NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no risk for any part of your content at any time. In comparison, all of the other file systems perform checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the rest of the disks as well and you can lose crucial info. Since this is not the case with ZFS, we guarantee the integrity of every single file you upload no matter what.
