Data corruption is the damage of data due to various software or hardware problems. After a file gets corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a serious problem for web hosting servers as fails are much more likely to happen on larger hard drives where vast volumes of information are placed. When a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a good one and it'll be copied on all drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often are unable to recognize corrupted files instantly or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the data uploaded in any shared hosting
account which is generated on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption using a unique checksum for each file. We will store your data on a large number of SSD drives which work in a RAID, so the very same files will exist on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file is different from what it should be, the file system swaps that file with an undamaged version from some other drive from the RAID. There's no other file system which uses checksums, so it is easy for data to be silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be resistant to silent data corruption because all our storage servers make use of the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to guarantee the integrity of each file. When you upload content to your account, it'll be kept on several redundant drives operating in a RAID i.e. the files will be the same across all disks. All of the copies of a particular file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, and if it identifies a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other disks. Even if there is an unforeseen power failure, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check which 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 truly protect your content from silent data corruption.
