Data corruption is the unintentional modification of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software fail, and as a result, a file can become partially or fully corrupted, so it'll no longer function properly as its bits shall be scrambled or lost. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In case such an issue appears and it isn't found by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that is part of a RAID array where the info is synced between various different drives, the corrupted file will be duplicated on all of the other drives and the damage will become long term. Numerous widespread file systems either don't feature real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a very common issue on web hosting servers where large volumes of info are stored.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data which you upload to your new cloud hosting account shall be ensured by the ZFS file system that we employ on our cloud platform. The vast majority of web hosting service providers, like our firm, use multiple hard disks to store content and considering that the drives work in a RAID, the same information is synchronized between the drives all the time. In case a file on a drive gets corrupted for reasons unknown, yet, it is very likely that it will be reproduced 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 file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from a different hard disk drive. As this happens instantly, there is no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption because all of our storage servers employ the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it will be placed on a couple of redundant drives employed in a RAID i.e. the files shall be the same across all drives. All the copies of a particular file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it detects a mismatch, which will indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other drives. Even if there's a sudden blackout, the data on the servers will not become corrupted and there will not be any need for a time-consuming system check which other file systems perform following 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.
