Data corruption is the damage of info because of various software or hardware fails. Once a file gets corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as failures are very likely to occur on larger hard disks where significant volumes of information are kept. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a healthy one and it'll be duplicated on all of the drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often cannot locate corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Website Hosting

We guarantee the integrity of the data uploaded in any shared website hosting account that is generated on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption via a unique checksum for every single file. We shall store your info on a large number of SSD drives which function in a RAID, so the same files will be present on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file differs from what it should be, the file system swaps that file with an undamaged copy from some other drive in the RAID. There's no other file system which uses checksums, so it is possible for data to become silently corrupted and the bad file to be duplicated on all drives with time, but since that can never happen on a server using ZFS, you don't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all our storage servers work with the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on several redundant drives working in a RAID i.e. the files will be the same across all drives. All of the copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, and if it finds a mismatch, which will indicate that one of the copies is corrupted, it will substitute that file with a good copy from one of the other drives. Even if there is an unforeseen power failure, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check which other file systems perform after some breakdown, extending the time needed for the server to go back online. ZFS is the only file system that can truly protect your content from silent data corruption.
