Data corruption is the accidental transformation of a file or the loss of information which often occurs during reading or writing. The reason can be hardware or software failure, and consequently, a file could become partially or fully corrupted, so it'll no longer function properly since its bits shall be scrambled or lost. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. If such an issue occurs and it's not recognized by the system or by an administrator, the data will be corrupted silently and when this happens on a drive which is part of a RAID array where the data is synced between various different drives, the corrupted file will be copied on all the other drives and the harm will be long term. Many frequently used file systems either don't have 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 common issue on hosting servers where large amounts of info are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the information uploaded in every shared web hosting account which is made on our cloud platform because we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We'll store your information on a large number of NVMe drives that operate in a RAID, so exactly the same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy version from a different drive within the RAID. There's no other file system which uses checksums, so it's possible for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you won't have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you acquire one of our semi-dedicated hosting packages, you won't have to worry about silent data corruption as we use ZFS - a high level file system which keeps track of all files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a couple of NVMe drives for redundancy, so if a drive fails, the other ones will take over. 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 immediately, so there will be no danger for any part of your content at any time. In contrast, all of the other file systems perform checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy may be replicated on the rest of the drives as well and you could lose precious information. Because this isn't the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
