The process of files being damaged owing to some hardware or software failure is known as data corruption and this is among the main problems that Internet hosting companies face as the larger a hard disk is and the more information is filed on it, the much more likely it is for data to be corrupted. You will find various fail-safes, still often the information is corrupted silently, so neither the particular file system, nor the admins detect anything. Thus, a bad file will be handled as a good one and if the hard drive is part of a RAID, that file will be copied on all other drives. Theoretically, this is done for redundancy, but in reality the damage will get worse. When some file gets corrupted, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most widely used server file systems feature various checks, they often fail to discover some problem early enough or require a long amount of time in order to check all of the files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the data uploaded in each cloud website hosting
account which is generated on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for each and every file. We shall store your information on a large number of SSD drives which work in a RAID, so identical files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file is different from what it should be, the file system replaces that file with a healthy copy from a different drive from the RAID. No other file system uses checksums, so it's easy for data to be silently damaged and the bad file to be replicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you purchase one of our semi-dedicated server
plans, you will not have to be concerned about silent data corruption as we use ZFS - an advanced file system that monitors 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 synchronized between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no danger for any part of your content at any moment. In contrast, all the other file systems carry out checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy could be replicated on the rest of the disks as well and you could lose important data. Because this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
