Data corruption is the damage of data caused by various software or hardware failures. When a file gets damaged, it will no longer work correctly, so an application will not start or shall give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as fails are very likely to happen on larger in size hard disks where substantial volumes of information are stored. In case a drive is part of a RAID and the information 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 will be copied on all of the drives, making the damage permanent. Lots of the file systems that run on web servers today often cannot recognize corrupted files right away or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the data uploaded in each cloud hosting
account that is created on our cloud platform since we employ the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption using a unique checksum for each and every file. We'll store your information on multiple SSD drives that work in a RAID, so identical files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy copy from some other drive inside the RAID. There's no other file system that uses checksums, so it's easy for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption since all our storage servers employ the reliable ZFS file system. What makes the aforementioned 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 kept on several redundant drives working in a RAID i.e. the files will be the same across all disk drives. All the copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates in real time, so if it discovers a mismatch, that will indicate that one of the copies is corrupted, it will replace 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 breakdown, prolonging the time needed for the server to go back online. ZFS is the only file system which can really protect your content from silent data corruption.
