Data corruption is the damage of info caused by various software or hardware failures. When a file gets damaged, it will no longer function accurately, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as fails are more likely to happen on larger in size hard drives where vast volumes of info are located. When a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's likely that the bad file will be treated as a regular one and will be duplicated on all of the drives, making the damage permanent. A huge number of the file systems which run on web servers these days often cannot discover corrupted files instantly or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Web Hosting
We warrant the integrity of the information uploaded in each and every cloud web hosting account which is made on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption via a unique checksum for each file. We shall store your data on a large number of SSD drives which operate in a RAID, so the very same files will be present on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file differs from what it should be, the file system replaces that file with an undamaged version from another drive from the RAID. No other file system uses checksums, so it is possible for data to be silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be resistant to silent data corruption since all our storage servers make use of the reliable ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of each and every file. When you upload content to your account, it'll be placed on several redundant drives in a RAID i.e. the files shall be the same on all disk drives. All copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, so if it detects a mismatch, which would indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other disks. Even if there is an unexpected 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 malfunction, extending the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
