Data corruption is the unintended modification of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file could become partially or entirely corrupted, so it'll no longer function properly because its bits shall be scrambled or missing. An image file, for example, will no longer show a true image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When such an issue appears and it is not noticed by the system or by an admin, the data will be corrupted silently and in case this happens on a drive which is part of a RAID array where the info is synced between different drives, the corrupted file will be replicated on all the other drives and the damage will become long term. A large number of widely used file systems either don't feature real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a very common problem on hosting servers where huge volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the info uploaded in any cloud hosting account which is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption thanks to a unique checksum for every single file. We shall store your data on a large number of SSD drives that work in a RAID, so the same files will be present on several places at once. ZFS checks the digital fingerprint of all files on all of the drives in real time and in case the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged version from another drive in the RAID. No other file system uses checksums, so it's possible for data to be silently corrupted and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you obtain one of our semi-dedicated hosting packages, you will not need to be concerned about silent data corruption as we use ZFS - a high level file system that monitors all files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This happens in real time, so there will be no danger for any part of your content at any moment. In contrast, all of the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you could lose precious data. Since this isn't the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
