Data corruption is the damage of data because of various hardware or software fails. When a file gets corrupted, it will no longer function properly, so an application will not start or shall give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for website hosting servers as problems are more likely to occur on larger hard drives where considerable volumes of information are located. In case a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as an ordinary one and it'll be duplicated on all of the drives, making the harm permanent. Lots of the file systems that operate on web servers nowadays often are not able to find corrupted files immediately or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data that you upload to your new web hosting
account will be ensured by the ZFS file system that we use on our cloud platform. The majority of hosting suppliers, like our firm, use multiple hard disks to keep content and considering that the drives work in a RAID, the exact same information is synchronized between the drives at all times. If a file on a drive becomes corrupted for whatever reason, however, it's very likely that it will be duplicated on the other drives as other file systems don't offer special checks for that. Unlike them, ZFS employs 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 shall be substituted with a good one from a different hard drive. Due to the fact that this happens right away, there's no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption since all of our storage servers use the efficient ZFS file system. What makes the aforementioned 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 placed on several redundant drives in a RAID i.e. the files shall be the same on all disks. All of the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it finds a mismatch, that would indicate that one of the copies is damaged, it'll replace that file with a healthy copy from one of the other drives. Even if there's an unforeseen blackout, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some breakdown, lengthening the time needed for the server to go back online. ZFS is the only file system which can truly protect your content from silent data corruption.
