Data corruption is the damage of info caused by various hardware or software failures. Once a file gets corrupted, it will no longer work as it should, so an app will not start or shall give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for hosting servers as problems are more likely to happen on larger in size hard drives where substantial volumes of info are kept. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as a healthy one and it'll be duplicated on all the drives, making the damage permanent. A lot of the file systems which run on web servers nowadays often are unable to detect corrupted files in real time or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account with our firm, you don't have to worry about any of your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform uses the state-of-the-art ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any data that you upload will be kept in a RAID i.e. simultaneously on numerous NVMes. All the file systems synchronize the files between the separate drives using this kind of a setup, but there is no real warranty that a file won't get corrupted. This may happen throughout the writing process on each drive and after that a damaged copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives instantly and when a corrupted file is located, it is swapped with a good copy with the correct checksum from some other drive. That way, your info will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you buy one of our semi-dedicated hosting packages, you won't have to be concerned about silent data corruption since we use ZFS - an advanced file system which checks all the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a couple of NVMe drives for redundancy, so if one drive fails, the other ones will take control. 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 a different drive. This is done in real time, so there will be no risk for any part of your content at any moment. By comparison, all of the other file systems perform checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you can lose critical information. Because this is not the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
