Data corruption is the damage of information because of various hardware or software fails. When a file is corrupted, it will no longer function as it should, so an app 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 identification by the system or an admin, that makes it a serious problem for website hosting servers as problems are very likely to happen on bigger hard disk drives where significant volumes of info are stored. When 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 bad file will be treated as an ordinary one and it will be duplicated on all drives, making the harm permanent. A huge number of the file systems which operate on web servers nowadays often cannot detect corrupted files right away or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Hosting

We warrant the integrity of the info uploaded in every single hosting account which is made on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for each file. We'll store your info on a number of SSD drives that operate in a RAID, so identical files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file is different 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 easy for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you do not have to concern yourself with 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 our storage servers use the effective ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to verify the integrity of every single 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 on all drives. All copies of a particular file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, so if it detects a mismatch, which will indicate that one of the copies is damaged, it'll replace that file with a good copy from one of the other drives. Even if there's an unexpected power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to return online. ZFS is the sole file system that can truly protect your content from silent data corruption.
