Data corruption is the damage of data caused by various hardware or software problems. The moment a file is damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a significant problem for web hosting servers as failures are very likely to happen on larger in size hard disks where significant volumes of info are stored. In case a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as an undamaged one and will be duplicated on all drives, making the damage permanent. A lot of the file systems that run on web servers today often are unable to locate corrupted files instantly 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 shall be ensured by the ZFS file system which we use on our cloud platform. Most web hosting service providers, including our firm, use multiple HDDs to keep content and since the drives work in a RAID, exactly the same data is synchronized between the drives all the time. In case a file on a drive gets corrupted for some reason, yet, it is very likely that it will be duplicated on the other drives as alternative file systems do not have special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from another drive. Due to the fact that this happens instantly, there is no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption because all our storage servers work with the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it will be kept on a couple of redundant drives working in a RAID i.e. the files shall be the same on all disk drives. All the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies in real time, and if it detects a mismatch, which would indicate that one of the copies is corrupted, it'll replace that file with a good copy from one of the other drives. Even if there's an unforeseen power loss, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, lengthening the time needed for the server to get back online. ZFS is the only file system which can truly protect your content from silent data corruption.
