Data corruption is the damage of information because of various hardware or software problems. When a file gets damaged, it will no longer work properly, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an administrator, which makes it a significant problem for hosting servers as failures are more likely to occur on bigger hard drives where large volumes of info are stored. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as an ordinary one and it'll be copied on all of the drives, making the damage permanent. A lot of the file systems that operate on web servers nowadays often are unable to recognize corrupted files in real time or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your sites in a shared website hosting account with our company, you don't need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform works with the outstanding ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on numerous NVMe drives. All the file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file will not be corrupted. This could happen at the time of the writing process on each drive and then a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all drives immediately and when a corrupted file is discovered, it's substituted with a good copy with the correct checksum from some other drive. That way, your information will continue to be intact 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 make use of the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it'll be kept on a couple of redundant drives in a RAID i.e. the files will be the same across all drives. All the copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it detects a mismatch, that would indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other disks. Even if there is an unforeseen power failure, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some breakdown, prolonging the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
