Data corruption is the unintentional change of a file or the losing of information which usually occurs during reading or writing. The reason could be hardware or software fail, and for that reason, a file may become partially or entirely corrupted, so it'll no longer function correctly as its bits will be scrambled or lacking. An image file, for instance, will no longer display an actual image, but a random combination 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 is not noticed by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that is a part of a RAID array where the info is synchronized between various different drives, the corrupted file shall be replicated on all the other drives and the harm will become long term. Many popular file systems either don't have real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where huge amounts of data are stored.

No Data Corruption & Data Integrity in Shared Hosting

We have dealt with the matter of silent data corruption on all of our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one on the market that checks all files in real time by employing 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 continually synced between them for redundancy. ZFS regularly examines the checksum of all files and when any file is detected as damaged, it is replaced immediately with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the remaining SSDs. ZFS requires lots of physical memory to execute the real-time checks and the benefit of our cloud hosting platform is that we use multiple powerful servers working together. In case 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 since all of our storage servers employ the efficient ZFS file system. What makes the aforementioned 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 kept on several redundant drives in a RAID i.e. the files will be the same across all disks. All copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, and if it discovers a mismatch, that will indicate that one of the copies is damaged, it'll substitute that file with a healthy copy from one of the other drives. Even if there is an unexpected blackout, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, lengthening the time needed for the server to return online. ZFS is the only file system that can really protect your content from silent data corruption.
