The process of files getting damaged as a consequence of some hardware or software failure is known as data corruption and this is one of the main problems that web hosting companies face as the larger a hard disk is and the more data is filed on it, the more likely it is for data to get corrupted. You can find different fail-safes, but often the data gets damaged silently, so neither the file system, nor the administrators detect a thing. Because of this, a corrupted file will be treated as a good one and if the HDD is part of a RAID, that file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. Once a given file gets corrupted, it will be partially or completely unreadable, so a text file will no longer be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most frequently used server file systems have various checks, they are likely to fail to discover some problem early enough or require an extensive time period to be able to check all the files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the info uploaded in each and every website hosting account that is made on our cloud platform as we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption using a unique checksum for each file. We shall store your information on a large number of SSD drives that function in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy copy from another drive in the RAID. There's no other file system which uses checksums, so it's possible 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 using ZFS, you will not have to worry about the integrity of your info.
