Data corruption is the damage of information due to various software or hardware problems. When a file is corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file shall 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 identification by the system or an administrator, that makes it a significant problem for web hosting servers as fails are very likely to happen on bigger hard disk drives where large volumes of information are placed. In case a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and will be duplicated on all drives, making the damage permanent. A lot of the file systems which run on web servers today often are unable to discover corrupted files in real time or they need time-consuming system checks through which the server is not functioning.
No Data Corruption & Data Integrity in Website Hosting
We warrant the integrity of the information uploaded in every single website hosting
account which is generated on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption through a unique checksum for each and every file. We will store your information on a number of SSD drives which function in a RAID, so the same files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all of the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from another drive in the RAID. No other file system uses checksums, so it is possible for data to become silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you go for one of our semi-dedicated server
plans, you won't need to worry about silent data corruption since we use ZFS - a high level file system which checks all files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a couple of SSD drives for redundancy, so if a 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 corrupted copy, it replaces it with a healthy one from another drive. This happens in real time, so there will be no danger for any part of your content at any time. By comparison, all the other file systems carry out checks after a system failure, 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 other drives as well and you could lose important info. Because this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
