No Data Corruption & Data Integrity in Cloud Hosting
We've resolved the issue of silent data corruption on our cloud hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems as it is the only one in existence which checks all files in real time by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as damaged, it's replaced instantly 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 copied on the rest of the SSDs. ZFS needs a lot of physical memory in order to perform the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple powerful servers working together. If you host your sites with us, your data will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be shielded from silent data corruption because all of our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it will be saved on several redundant drives operating in a RAID i.e. the files will be the same on all disks. All copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, and if it registers a mismatch, which will indicate that one of the copies is corrupted, it'll substitute 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 malfunction, prolonging the time needed for the server to go back online. ZFS is the sole file system which can really protect your content from silent data corruption.
