Data corruption is the damage of info due to various hardware or software fails. When a file gets corrupted, it will no longer function accurately, so an application will not start or shall give errors, a text file will be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, that makes it a serious problem for web hosting servers as fails are more likely to happen on bigger hard disk drives where considerable volumes of information are stored. When a drive is part of a RAID and the information on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as a healthy one and will be copied on all the drives, making the damage permanent. A huge number of the file systems that run on web servers nowadays often are unable to detect corrupted files immediately or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Cloud Website Hosting

In case you host your websites in a cloud website hosting account with our firm, you won't have to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform uses the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the data that you upload will be saved in a RAID i.e. simultaneously on many SSDs. All file systems synchronize the files between the separate drives using such a setup, but there's no real guarantee that a file won't get corrupted. This may occur during the writing process on any drive and then a corrupted copy can be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives instantly and when a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. In this way, your info will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you obtain one of our semi-dedicated server packages, you won't need to worry about silent data corruption as we use ZFS - a high level file system which keeps track of all the files in real time. Every 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 synced between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all 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 instantly, so there will be no danger for any part of your content at any time. In contrast, all the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you could lose critical data. As this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
