Data corruption is the damage of data due to various software or hardware failures. When a file gets damaged, it will no longer function properly, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as problems are more likely to occur on larger hard disk drives where large volumes of info are kept. 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 today often are not able to identify corrupted files in real time or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Shared Website Hosting
If you host your sites in a shared website hosting
account with our company, you won't have to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the state-of-the-art ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. Any data that you upload will be kept in a RAID i.e. simultaneously on many different SSDs. 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 will not get corrupted. This may occur throughout the writing process on any drive and afterwards a corrupted copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all the drives right away and in case a corrupted file is located, it's replaced with a good copy with the correct checksum from another drive. In this way, your data will stay undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you buy one of our semi-dedicated hosting
solutions, you won't need to be concerned about silent file corruption as we use ZFS - a high level file system that checks all files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no danger for any part of your content at any time. By comparison, alternative file systems carry out checks only 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 corrupted copy could be replicated on the remaining disks as well and you may lose precious info. Since this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
