Data corruption is the damage of information because of various hardware or software fails. The moment a file gets corrupted, it will no longer function correctly, so an app will not start or shall give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, which makes it a significant problem for website hosting servers as problems are very likely to happen on bigger hard disks where considerable volumes of info are stored. If a drive is part of a RAID and the data on it is copied on other drives for redundancy, it is more than likely that the damaged file will be treated as a standard one and it'll be copied on all drives, making the harm permanent. Lots of the file systems which run on web servers these days often are unable to identify corrupted files in real time or they need time-consuming system checks through which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Website Hosting

We have resolved the matter of silent data corruption on our cloud website hosting servers by using the amazing Z file system, or ZFS. The latter is better than other file systems as it is the only one on the market that checks all the files instantly by employing a checksum - a digital identifier which is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and continually synchronized between them for redundancy. ZFS regularly compares the checksum of all files and in case any file is detected as damaged, it is replaced immediately with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the remaining SSDs. ZFS needs plenty of physical memory to perform the real-time checks and the advantage of our cloud web hosting platform is that we take advantage of multiple powerful servers working together. If you host your Internet sites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you obtain one of our semi-dedicated server plans, you won't have to be concerned about silent file corruption as we use ZFS - an advanced file system which monitors all the files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no danger for any part of your content at any time. By comparison, all of the other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a bad copy can be replicated on the rest of the disks as well and you may lose crucial information. Since this is not the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
