The process of files getting corrupted because of some hardware or software failure is called data corruption and this is one of the main problems which web hosting companies face since the larger a hard disk drive is and the more info is stored on it, the more likely it is for data to be corrupted. There are various fail-safes, but often the information is damaged silently, so neither the file system, nor the admins notice a thing. Because of this, a corrupted file will be handled as a good one and if the hard disk is a part of a RAID, the file will be duplicated on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will be worse. The moment a given file gets corrupted, it will be partly or entirely unreadable, so a text file will not be readable, an image file will present a random mix of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most popular server file systems have various checks, they are likely to fail to find some problem early enough or require a vast amount of time to check all the files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

If you host your websites in a shared hosting account from our firm, you do not need to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the state-of-the-art ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be stored in a RAID i.e. simultaneously on many different NVMe drives. All file systems synchronize the files between the different drives using this kind of a setup, but there is no real guarantee that a file will not be corrupted. This could occur during the writing process on each drive and after that a damaged copy can be copied on the other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all the drives right away and in case a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. In this way, your data will remain undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption since all our storage servers use the advanced ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of each file. When you upload content to your account, it'll be placed on several redundant drives employed in a RAID i.e. the files shall be the same across all disks. 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 right away, so if it finds a mismatch, which will indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other drives. Even if there is an unforeseen power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, lengthening the time needed for the server to return online. ZFS is the only file system that can really protect your content from silent data corruption.
