No Data Corruption & Data Integrity
See what No Data Corruption & Data Integrity is and how it can be good for the files inside your website hosting account.
Data corruption is the unintended transformation of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file may become partially or fully corrupted, so it will no longer work properly because its bits will be scrambled or lost. An image file, for instance, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. When this kind of an issue appears and it isn't identified by the system or by an administrator, the data will become corrupted silently and if this happens on a disk drive that's part of a RAID array where the information is synced between various drives, the corrupted file shall be replicated on all other drives and the harm will become permanent. Numerous widely used file systems either don't feature real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common matter on hosting servers where huge amounts of data are stored.
No Data Corruption & Data Integrity in Shared Website Hosting
We have resolved the problem of silent data corruption on all our shared website hosting
servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one out there which checks all of the files in real time by employing a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as corrupted, it is replaced quickly with a good copy from some other disk. As this happens in real time, there is no risk that a damaged 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 benefit of our cloud web hosting platform is that we take advantage of multiple powerful servers working together. If you host your sites 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 protected against silent data corruption since 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 verify the integrity of each and every file. When you upload content to your account, it'll be kept on several redundant drives in a RAID i.e. the files shall be the same on all drives. All of the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies quickly, so if it discovers a mismatch, that would indicate that one of the copies is corrupted, it will replace that file with a good copy from one of the other drives. Even if there is an unexpected blackout, 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, extending the time needed for the server to go back online. ZFS is the file system that can really protect your content from silent data corruption.
