Data corruption is the damage of information due to various software or hardware problems. Once a file is damaged, it will no longer work accurately, so an application will not start or will give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as failures are much more likely to occur on bigger hard drives where significant volumes of information are stored. In case a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as an undamaged one and will be duplicated on all drives, making the damage permanent. A huge number of the file systems which operate on web servers nowadays often are not able to recognize corrupted files right away or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Website Hosting

In case you host your Internet sites in a website hosting account with our firm, you won't have to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform works with the cutting-edge ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each file. Any info that you upload will be saved in a RAID i.e. simultaneously on a large number of NVMes. All of the file systems synchronize the files between the separate drives with this type of a setup, but there's no real warranty that a file won't get corrupted. This could occur throughout the writing process on any drive and after that a corrupted copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives immediately and when a corrupted file is located, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will continue to be intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you go for one of our semi-dedicated server plans, you will not need to be concerned about silent data corruption because we use ZFS - a high level file system that keeps track of all the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between multiple NVMe drives for redundancy, so if a 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 corrupted copy, it replaces it with a healthy one from a different drive. This happens instantly, so there will be no danger for any part of your content at any moment. In comparison, all the other file systems execute checks after a system malfunction, 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 could be replicated on the rest of the disks as well and you could lose important info. Since this isn't the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
