Data corruption is the damage of data caused by various software or hardware fails. After a file is damaged, it will no longer function properly, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an administrator, which makes it a serious problem for hosting servers as fails are much more likely to happen on larger hard drives where considerable volumes of information are stored. When a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as a regular one and it will be copied on all the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often cannot locate corrupted files right away or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your sites in a shared hosting account from our firm, you do not have to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All the info that you upload will be kept in a RAID i.e. simultaneously on multiple 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 occur during the writing process on any drive and then a bad copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all the drives in real time and in the event that a corrupted file is located, it is replaced with a good copy with the correct checksum from some other drive. That way, your information will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption as all of our storage servers use the state-of-the-art ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it'll be placed on a couple of redundant drives working in a RAID i.e. the files will be the same on all disks. All the copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, and if it discovers a mismatch, which would indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, extending the time needed for the server to go back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
