Data corruption is the damage of information caused by various software or hardware failures. When a file gets corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file can be partially or entirely 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 admin, which makes it a serious problem for hosting servers as fails are much more likely to occur on bigger hard disks where large volumes of information are kept. In case a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the bad file will be treated as an undamaged one and it will be copied on all the drives, making the harm permanent. Lots of the file systems that operate on web servers today often are unable to identify corrupted files instantly or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Hosting
The integrity of the data which you upload to your new hosting
account shall be guaranteed by the ZFS file system which we employ on our cloud platform. Most internet hosting suppliers, like our company, use multiple hard disk drives to store content and because the drives work in a RAID, the exact same information is synchronized between the drives all the time. If a file on a drive is damaged for whatever reason, however, it is more than likely that it will be copied on the other drives as other file systems don't offer special checks for that. 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, so the damaged copy shall be swapped with a good one from another hard disk drive. Since this happens instantly, 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 resistant to silent data corruption since all of our storage servers use the advanced ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to guarantee the integrity of every single file. When you upload content to your account, it'll be kept on several redundant drives employed in a RAID i.e. the files shall be the same on all disks. 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 right away, so if it finds a mismatch, which would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
