The process of files getting damaged as a result of some hardware or software failure is called data corruption and this is one of the main problems that 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 get corrupted. You will find a couple of fail-safes, but often the data gets damaged silently, so neither the particular file system, nor the admins see anything. Thus, a damaged file will be treated as a standard one and if the hard drive is a part of a RAID, that file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will get worse. Once some file gets damaged, it will be partly or entirely unreadable, so a text file will no longer be readable, an image file will display a random blend of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your site content. Although the most popular server file systems have various checks, they are likely to fail to detect a problem early enough or require an extensive amount of time to check all the files and the hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the info uploaded in every shared hosting account that is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for every single file. We'll store your info on a large number of SSD drives which operate in a RAID, so the exact same files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all 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 copy from some other drive in the RAID. There's no other file system that uses checksums, so it is easy for data to become silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption because all our storage servers work with the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it will be placed on several redundant drives working in a RAID i.e. the files will be the same on all drives. All of the copies of a specific file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it discovers a mismatch, that will indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other drives. Even if there is a sudden power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, extending the time needed for the server to get back online. ZFS is the only file system that can really protect your content from silent data corruption.
