The process of files getting damaged resulting from 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 disk is and the more data is stored on it, the much more likely it is for data to be corrupted. There are a couple of fail-safes, still often the data is damaged silently, so neither the file system, nor the admins notice a thing. As a result, a bad file will be treated as a standard one and if the hard drive is part of a RAID, the file will be duplicated on all other drives. In theory, this is for redundancy, but in reality the damage will get even worse. When a given file gets corrupted, it will be partly or entirely unreadable, therefore a text file will not be readable, an image file will present a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most frequently used server file systems have various checks, they often fail to identify a problem early enough or require an extensive time period in order to check all files and the web server will not be functional for the time being.

No Data Corruption & Data Integrity in Web Hosting

In case you host your sites in a web hosting account with our company, you will not need to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. All file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file won't be corrupted. This may occur during the writing process on each drive and afterwards a damaged copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives immediately and in case a corrupted file is discovered, it is replaced with a good copy with the correct checksum from another drive. That way, your information will remain unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption because all of our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to guarantee the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives in a RAID i.e. the files shall be the same across all disks. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, and if it registers a mismatch, that would indicate that one of the copies is corrupted, it will substitute that file with a good copy from one of the other drives. Even if there's an unforeseen blackout, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform following some malfunction, lengthening the time needed for the server to get back online. ZFS is the file system that can truly protect your content from silent data corruption.
