The process of files being damaged as a consequence of some hardware or software failure is referred to as data corruption and this is among the main problems that web hosting companies face because the larger a hard drive is and the more information is placed on it, the much more likely it is for data to become corrupted. You can find a couple of fail-safes, but often the info gets damaged silently, so neither the particular file system, nor the admins notice a thing. As a result, a bad file will be treated as a regular one and if the hard disk is a part of a RAID, that file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will be even worse. The moment some file gets damaged, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will display a random combination 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 well-known server file systems include various checks, they frequently fail to identify a problem early enough or require an extensive amount of time to check all files and the hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Hosting
We guarantee the integrity of the data uploaded in every hosting
account which is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each and every file. We shall store your information on multiple SSD drives that function in a RAID, so the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged copy from a different drive from the RAID. There's no other file system that uses checksums, so it is possible for data to become silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be shielded from silent data corruption because all of our storage servers use the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to verify the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all 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 copies in real time, and if it registers a mismatch, which would indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other drives. Even if there is an unexpected blackout, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to return online. ZFS is the sole file system which can truly protect your content from silent data corruption.
