Data corruption is the damage of data because of various hardware or software fails. After a file is damaged, it will no longer work accurately, so an application will not start or will give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open then 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 significant problem for hosting servers as fails are much more likely to occur on bigger hard disk drives where considerable volumes of information are kept. If a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it is likely that the bad file will be treated as a good one and it will be copied on all the drives, making the damage permanent. A lot of the file systems that run on web servers these days often cannot detect corrupted files right away or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Web Hosting
We guarantee the integrity of the info uploaded in any web hosting
account which is generated on our cloud platform because we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption through a unique checksum for each file. We'll store your info on multiple SSD drives that operate in a RAID, so identical files will be accessible on several places at once. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged version from a different drive from the RAID. There's no other file system which uses checksums, so it's possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you do not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be resistant to silent data corruption as all of our storage servers work with the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it'll be placed on a couple of redundant drives working in a RAID i.e. the files will be the same across all disk drives. All of the copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, which will indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other disks. Even if there is an unexpected blackout, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check which other file systems perform following some breakdown, lengthening the time needed for the server to go back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
