Data corruption is the damage of info caused by various hardware or software fails. The moment a file is corrupted, it will no longer work accurately, so an application will not start or will give errors, a text file could 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 harmed without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as problems are more likely to occur on larger hard drives where considerable volumes of info are placed. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as a healthy one and will be duplicated on all of the drives, making the harm permanent. A lot of the file systems which run on web servers these days often are unable to recognize corrupted files immediately or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data which you upload to your new shared web hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. Most of the internet hosting providers, like our company, use multiple hard disks to store content and because the drives work in a RAID, exactly the same information is synchronized between the drives at all times. If a file on a drive is damaged for reasons unknown, yet, it is very likely that it will be copied on the other drives because alternative file systems do not include special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be replaced with a good one from a different hard drive. As this happens instantly, there's no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption as all of our storage servers employ the advanced ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it'll be kept on a couple of redundant drives working in a RAID i.e. the files will be the same across all disk drives. All of the copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it discovers a mismatch, that will indicate that one of the copies is corrupted, it'll replace that file with a good copy from one of the other disks. Even if there is a sudden power failure, the data on the servers will not be corrupted and there will not 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 get back online. ZFS is the sole file system that can truly protect your content from silent data corruption.
