No Data Corruption & Data Integrity in Shared Hosting
We've tackled the issue of silent data corruption on our shared hosting servers by using the advanced Z file system, or ZFS. The latter is superior to other file systems because it is the only one in existence that checks all files immediately by using a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS constantly compares the checksum of all files and if any file is detected as damaged, it's replaced right away 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 duplicated on the other SSDs. ZFS needs plenty of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we use multiple very powerful servers working together. In case you host your sites with us, your information will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't experience any silent data corruption issues in case you get one of our semi-dedicated hosting packages because the ZFS file system that we work with on our cloud hosting platform uses checksums to make sure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any chance of the corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system you can find that uses checksums, which makes it much more reliable than other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
