Data corruption is the damage of info caused by various software or hardware fails. The moment a file is corrupted, it will no longer function correctly, so an app will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as problems are much more likely to happen on larger in size hard disks where significant volumes of information are located. When a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a healthy one and it'll be duplicated on all the drives, making the damage permanent. Lots of the file systems that run on web servers these days often are unable to find corrupted files instantly or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data that you upload to your new shared web hosting
account will be ensured by the ZFS file system which we take advantage of on our cloud platform. Most internet hosting providers, including our firm, use multiple hard disk drives to store content and considering that the drives work in a RAID, exactly the same data is synchronized between the drives at all times. If a file on a drive gets corrupted for reasons unknown, yet, it's likely that it will be copied on the other drives because other file systems don't offer special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be replaced with a good one from a different hard disk. As this happens right away, there is no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption because all of our storage servers use the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it will be placed on several redundant drives employed in a RAID i.e. the files shall be the same on all drives. All of the copies of a specific file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it detects a mismatch, which would indicate that one of the copies is damaged, it will replace that file with a good copy from one of the other disks. Even if there's a sudden power loss, the data on the servers will not be corrupted and there won't 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 return online. ZFS is the file system which can really protect your content from silent data corruption.
