No Data Corruption & Data Integrity in Web Hosting
We've resolved the matter of silent data corruption on all of our web hosting servers by using the modern Z file system, or ZFS. The latter is superior to other file systems as it is the only one on the market that checks all of the files immediately by employing a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and constantly synced between them for redundancy. ZFS regularly analyzes the checksum of all files and if any file is detected as damaged, it is replaced quickly with a good copy from another disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the rest of the SSDs. ZFS needs plenty of physical memory in order to carry out the real-time checks and the benefit of our cloud web hosting platform is that we use multiple powerful servers working together. In case you host your websites with us, your info will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be resistant to silent data corruption because all of our storage servers employ the effective ZFS file system. What makes the latter 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'll be saved on a couple of redundant drives working in a RAID i.e. the files will be the same on all drives. All copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, and if it detects a mismatch, that would indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other drives. Even if there's a sudden power failure, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some failure, extending the time needed for the server to get back online. ZFS is the only file system that can really protect your content from silent data corruption.
