Data corruption is the damage of information caused by various software or hardware failures. After a file is corrupted, it will no longer function correctly, so an app will not start or will give errors, a text file could be partially or completely 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 administrator, that makes it a serious problem for hosting servers as fails are more likely to happen on larger hard disk drives where significant volumes of info are placed. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it's very likely that the bad file will be treated as a good one and it'll be copied on all drives, making the harm permanent. A lot of the file systems that operate on web servers these days often cannot locate corrupted files in real time or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Shared Web Hosting
If you host your Internet sites in a shared web hosting account from our company, you don't need to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform works with the revolutionary ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be stored in a RAID i.e. simultaneously on a number of SSDs. Many file systems synchronize the files between the different drives with this type of a setup, but there is no real warranty that a file will not get corrupted. This could occur during the writing process on each drive and after that a damaged copy may be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives live and in case a corrupted file is identified, it's substituted with a good copy with the correct checksum from another drive. By doing this, your information will remain undamaged 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 shielded from silent data corruption as all our storage servers work with the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order 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 shall be the same across all disks. All the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, and if it finds a mismatch, which would indicate that one of the copies is corrupted, it will replace that file with a healthy copy from one of the other disks. Even if there's a sudden 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 after some breakdown, extending the time needed for the server to go back online. ZFS is the only file system that can really protect your content from silent data corruption.
