Data corruption is the damage of data because of various software or hardware fails. The moment a file gets damaged, it will no longer work accurately, so an app will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as fails are very likely to occur on larger in size hard drives where substantial 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 is more than likely that the damaged file will be treated as a good one and will be copied on all the drives, making the harm permanent. Lots of the file systems which run on web servers these days often cannot recognize corrupted files in real time or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Website Hosting
If you host your Internet sites in a website hosting
account with our company, you don't have to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform uses the outstanding ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. All the file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file will not be corrupted. This could occur throughout the writing process on each drive and afterwards a corrupted copy may be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all the drives right away and in the event that a corrupted file is found, it is swapped with a good copy with the correct checksum from some other drive. That way, your information will stay undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you purchase one of our semi-dedicated hosting
packages, you won't need to be concerned about silent data corruption since we use ZFS - an advanced file system which monitors all the files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple 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 in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no threat for any part of your content at any time. By comparison, alternative file systems carry out checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you can lose crucial info. Since this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
