Data corruption is the damage of information because of various software or hardware failures. After a file gets damaged, it will no longer function correctly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a serious problem for website hosting servers as fails are very likely to happen on bigger hard disk drives where significant volumes of info are located. If a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as a regular one and it will be copied on all drives, making the damage permanent. Lots of the file systems that run on web servers nowadays often are not able to recognize corrupted files right away or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Website Hosting

We warrant the integrity of the data uploaded in any shared website hosting account which is made on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your info on multiple NVMe drives which work in a RAID, so exactly the same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file differs from what it should be, the file system swaps that file with a healthy copy from another drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to be silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server running ZFS, you will not have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you get one of our semi-dedicated server packages, you will not have to worry about silent file corruption because we use ZFS - an advanced file system which keeps track of all of the files in real time. Whenever you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This 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 a different drive. This happens right away, so there will be no risk 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 are unable to detect silently corrupted files, so a bad copy may be replicated on the rest of the disks as well and you can lose precious data. Because this is not the case with ZFS, we warrant the integrity of every single file you upload no matter what.
