Data corruption is the damage of information due to various hardware or software failures. After a file is damaged, it will no longer function as it should, so an application will not start or shall give errors, a text file could be partially or completely 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 admin, that makes it a significant problem for hosting servers as failures are very likely to happen on bigger hard drives where considerable volumes of info are kept. If a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as a healthy one and it'll be copied on all drives, making the damage permanent. A huge number of the file systems that operate on web servers nowadays often are not able to recognize corrupted files right away or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Web Hosting

We guarantee the integrity of the information uploaded in every cloud web hosting account that is generated on our cloud platform as we employ 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 and every file. We shall store your info on a number of SSD drives that operate in a RAID, so identical files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and if the checksum of any file differs from what it has 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 is possible for data to get silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server using 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 protected against silent data corruption since all of 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 verify the integrity of every single file. When you upload content to your account, it'll be kept on a couple of redundant drives operating in a RAID i.e. the files shall be the same across all drives. All copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates quickly, and if it discovers a mismatch, that will indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, lengthening the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
