Data corruption is the damage of information because of various hardware or software failures. After a file gets corrupted, it will no longer work as it should, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, that makes it a significant problem for website hosting servers as failures are much more likely to happen on larger in size hard disk drives where considerable volumes of information are kept. If a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as an undamaged one and will be copied on all of the drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often cannot recognize corrupted files in real time or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting account will be guaranteed by the ZFS file system that we work with on our cloud platform. Most web hosting providers, including our firm, use multiple hard disk drives to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives all of the time. When a file on a drive is corrupted for whatever reason, however, it is very likely that it will be duplicated on the other drives because alternative file systems do not offer special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy shall be substituted with a good one from another drive. Since this happens in real time, there's no risk for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be resistant to silent data corruption as all of our storage servers make use of the effective ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each and every 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 on all disk drives. All of the copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, and if it discovers a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other drives. Even if there is an unexpected power failure, the data on the servers won't be 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 file system that can really protect your content from silent data corruption.
