Data corruption is the damage of info because of various software or hardware fails. The moment a file gets corrupted, it will no longer function as it should, so an application will not start or shall give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an administrator, which makes it a serious problem for hosting servers as failures are very likely to happen on larger in size hard disks where vast volumes of info are stored. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as a healthy one and will be copied on all the drives, making the damage permanent. A lot of the file systems that operate on web servers today often are unable to locate corrupted files right away or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account shall be ensured by the ZFS file system that we take advantage of on our cloud platform. The majority of internet hosting service providers, including our firm, use multiple hard disks to store content and since the drives work in a RAID, the exact same information is synchronized between the drives all the time. If a file on a drive becomes damaged for reasons unknown, however, it is likely that it will be copied on the other drives since alternative file systems do not include special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the bad copy will be substituted with a good one from another disk drive. As this happens immediately, there's 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 protected against silent data corruption since all our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it will be stored on a couple of redundant drives being employed in a RAID i.e. the files shall be the same on all disk drives. All the copies of a particular file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, and if it finds a mismatch, that will indicate that one of the copies is damaged, it'll substitute that file with a healthy copy from one of the other drives. Even if there is an unforeseen blackout, 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 breakdown, extending the time needed for the server to return online. ZFS is the sole file system which can really protect your content from silent data corruption.
