Data corruption is the damage of info caused by various software or hardware failures. When a file gets corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file can be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a significant problem for website hosting servers as fails are more likely to occur on bigger hard disks where vast volumes of information are kept. When a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a regular one and it will be duplicated on all the drives, making the damage permanent. A lot of the file systems that operate on web servers today often cannot recognize corrupted files in real time or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Web Hosting

In case you host your sites in a web hosting account with our company, you do not need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the advanced ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on multiple 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 throughout the writing process on each drive and after that a corrupted copy can be copied on all other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all the drives instantly and when a corrupted file is identified, it's swapped with a good copy with the correct checksum from another drive. This way, your info will remain 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 resistant to silent data corruption since all our storage servers employ the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be saved on several redundant drives operating 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 drives and ZFS will compare the checksums of the copies right away, and if it registers a mismatch, that would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other disks. Even if there's a sudden power loss, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some failure, lengthening the time needed for the server to get back online. ZFS is the only file system which can really protect your content from silent data corruption.
