The process of files getting corrupted owing to some hardware or software failure is referred to as data corruption and this is one of the main problems that web hosting companies face as the larger a hard drive is and the more information is filed on it, the more likely it is for data to be corrupted. You can find a couple of fail-safes, but often the information becomes damaged silently, so neither the file system, nor the admins detect a thing. Because of this, a corrupted file will be treated as a good one and if the hard disk drive is part of a RAID, that particular file will be copied on all other disk drives. In principle, this is done for redundancy, but in practice the damage will get even worse. When some file gets corrupted, it will be partially or entirely unreadable, so a text file will no longer be readable, an image file will show a random blend of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your website content. Although the most popular server file systems have various checks, they quite often fail to discover some problem early enough or require a vast period of time to be able to check all files and the web server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the data uploaded in each and every shared hosting
account which is created on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption thanks to a unique checksum for every single file. We will store your data on a number of SSD drives that function in a RAID, so identical files will exist on several places at the same time. ZFS checks the digital fingerprint of all of 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 swaps that file with a healthy version from a different drive in the RAID. No other file system uses checksums, so it is easy for data to become silently corrupted and the bad file to be duplicated on all drives with time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be shielded from silent data corruption since all of our storage servers make use of the innovative ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each and every file. When you upload content to your account, it'll be kept on several redundant drives operating in a RAID i.e. the files will be the same on all disk drives. All of the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, and if it identifies a mismatch, that will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other drives. Even if there's an unforeseen blackout, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, prolonging the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
