The process of files getting damaged caused by some hardware or software failure is known 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 filed on it, the much more likely it is for data to be corrupted. You'll find different fail-safes, still often the data is damaged silently, so neither the particular file system, nor the admins see a thing. As a result, a bad file will be handled as a standard one and if the HDD 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 get worse. When a given file gets damaged, it will be partially or fully unreadable, therefore a text file will no longer be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your site content. Although the most widespread server file systems include various checks, they often fail to detect a problem early enough or require an extensive time period in order to check all of the files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your websites in a cloud hosting account with our company, you do not need to worry about your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be kept in a RAID i.e. simultaneously on a number of NVMe drives. All file systems synchronize the files between the different drives with such a setup, but there is no real warranty that a file will not be corrupted. This could happen at the time of the writing process on each drive and afterwards a corrupted copy can be copied on all other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all drives right away and when a corrupted file is identified, it's substituted with a good copy with the correct checksum from another drive. By doing this, your data will stay unharmed no matter what, even if a whole drive fails.

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 make use of the reliable ZFS file system. What makes the latter 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 saved on several redundant drives working in a RAID i.e. the files will be the same across all disks. All copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, so if it discovers a mismatch, which will indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other disks. Even if there is 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 malfunction, lengthening the time needed for the server to go back online. ZFS is the file system which can truly protect your content from silent data corruption.
