The process of files getting corrupted because of some hardware or software failure is called data corruption and this is one of the main problems that web hosting companies face since the larger a hard drive is and the more data is placed on it, the much more likely it is for data to be corrupted. You can find a couple of fail-safes, yet often the data becomes corrupted silently, so neither the particular file system, nor the administrators detect a thing. Because of this, a corrupted file will be handled as a regular one and if the hard disk is a part of a RAID, that file will be duplicated on all other drives. Theoretically, this is for redundancy, but in practice the damage will be even worse. The moment a file gets corrupted, it will be partially or entirely unreadable, therefore a text file will not be readable, an image file will show a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your site content. Although the most well-known server file systems feature various checks, they quite often fail to identify some problem early enough or require a long amount of time in order to check all of the files and the server will not be functional for the time being.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data which you upload to your new cloud web hosting account will be guaranteed by the ZFS file system that we use on our cloud platform. Most of the hosting providers, including our company, use multiple HDDs to keep content and because the drives work in a RAID, the exact same info is synchronized between the drives all of the time. In case a file on a drive becomes corrupted for reasons unknown, yet, it is more than likely that it will be copied on the other drives since alternative file systems do not have special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be swapped with a good one from another drive. Because this happens right away, there is no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you obtain one of our semi-dedicated hosting solutions, you won't have to be concerned about silent file corruption as we use ZFS - an advanced file system which keeps track of all files in real time. Whenever you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no danger for any part of your content at any time. By comparison, all the other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you can lose precious information. As this isn't the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
