Data corruption is the accidental transformation of a file or the loss of information which usually occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it will no longer function correctly since its bits shall be scrambled or missing. An image file, for instance, will no longer present an actual image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. When this kind of a problem appears and it's not identified by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive which is a part of a RAID array where the data is synchronized between various drives, the corrupted file will be reproduced on all of the other drives and the damage will be long term. A number of popular file systems either don't feature real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where substantial volumes of information are kept.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account will be guaranteed by the ZFS file system which we make use of on our cloud platform. Most of the web hosting service providers, including our firm, use multiple hard drives to keep content and considering that the drives work in a RAID, the same data is synchronized between the drives all of the time. When a file on a drive gets damaged for reasons unknown, however, it is likely that it will be reproduced on the other drives since other file systems do not feature special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, therefore the bad copy will be swapped with a good one from another hard disk drive. Due to the fact that this happens instantly, there's no possibility 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 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 and every file. When you upload content to your account, it'll be saved 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 particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, so if it identifies a mismatch, that would indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other drives. Even if there is a sudden blackout, the data on the servers won't be corrupted and there won't 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 get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
