No Data Corruption & Data Integrity in Shared Hosting
We have tackled the problem of silent data corruption on our shared hosting servers by using the leading-edge Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one on the market that checks all of the files in real time by using a checksum - a digital identifier which is unique for each file. When you upload content to your account, it will be stored on several SSD drives and regularly synced between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as damaged, it's replaced instantly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining SSDs. ZFS needs a lot of physical memory in order to perform the real-time checks and the benefit 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 Servers
Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers employ the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of each and every file. When you upload content to your account, it'll be stored on several redundant drives employed in a RAID i.e. the files shall be the same across all disk drives. All the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, so if it identifies a mismatch, which will indicate that one of the copies is damaged, it'll substitute that file with a good copy from one of the other disks. Even if there's an unexpected 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 after some breakdown, lengthening the time needed for the server to get back online. ZFS is the only file system which can truly protect your content from silent data corruption.
