Data corruption is the unintentional change of a file or the losing of info which often occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file can become partially or entirely corrupted, so it'll no longer function properly as its bits will be scrambled or lost. An image file, for instance, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In case this kind of a problem appears and it is not found by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that is a part of a RAID array where the data is synced between various different drives, the corrupted file will be duplicated on all other drives and the harm will be long term. Numerous widespread file systems either don't feature real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where huge volumes of data are kept.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we employ on our cloud platform. The majority of hosting providers, including our firm, use multiple HDDs to keep content and since the drives work in a RAID, the exact same info is synchronized between the drives all the time. If a file on a drive becomes corrupted for whatever reason, yet, it is likely that it will be duplicated on the other drives because alternative file systems do not have special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the damaged copy will be substituted with a good one from another hard drive. As this happens right away, there's no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not experience any kind of silent data corruption issues should you get one of our semi-dedicated server solutions because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all the files are intact all the time. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. As we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. In case it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any possibility of the corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system on the market that uses checksums, which makes it much more reliable than other file systems which are unable to detect silent data corruption and duplicate bad files across hard drives.
