No Data Corruption & Data Integrity in Web Hosting
We have tackled the matter of silent data corruption on all our web hosting servers by using the advanced Z file system, or ZFS. The latter is better than other file systems as it is the only one in existence which checks all the files immediately by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several SSD drives and frequently synced between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as corrupted, it is replaced immediately with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the rest of the SSDs. ZFS requires lots of physical memory to execute the real-time checks and the benefit of our cloud website hosting platform is that we use multiple powerful servers working together. If you host your sites with us, your data will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be shielded from silent data corruption since all our storage servers work with the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it will be placed on a couple of redundant drives being employed in a RAID i.e. the files shall be the same across all disks. All of the copies of a given file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other drives. Even if there's a sudden blackout, the data on the servers will not get corrupted and there will not 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 get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
