Data corruption is the damage of info because of various software or hardware failures. After a file gets corrupted, it will no longer work correctly, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, which makes it a serious problem for website hosting servers as failures are much more likely to occur on bigger hard disks where significant volumes of info are located. If a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a standard one and it will be copied on all drives, making the damage permanent. Lots of the file systems which operate on web servers today often cannot recognize corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Web Hosting

If you host your Internet sites in a web hosting account from our firm, you won't need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform uses the leading-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on multiple NVMe drives. All of the file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file will not be corrupted. This can occur during the writing process on any drive and after that a damaged copy may 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 immediately and in case a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. By doing this, your info will remain intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption because all our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it will be placed on several redundant drives being employed in a RAID i.e. the files will be the same across all disks. All copies of a given file will feature 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 will indicate that one of the copies is corrupted, it'll swap that file with a healthy copy from one of the other disks. Even if there's a sudden power failure, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check which 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.
