Data corruption is the damage of information caused by various software or hardware problems. When a file is corrupted, it will no longer function correctly, so an application will not start or shall give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, which makes it a significant problem for website hosting servers as problems are very likely to happen on larger in size hard disk drives where considerable volumes of info are stored. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a healthy one and it'll be duplicated on all of the drives, making the damage permanent. A huge number of the file systems which run on web servers these days often are not able to locate corrupted files in real time or they need time-consuming system checks through which the server isn't working.

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 which we make use of on our cloud platform. The vast majority of hosting providers, including our company, use multiple hard disks to store content and because the drives work in a RAID, the same info is synchronized between the drives all of the time. In case a file on a drive gets damaged for some reason, however, it's more than likely that it will be reproduced on the other drives because other file systems don't offer special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy will be substituted with a good one from another hard disk. Due to the fact that this happens in real time, there is no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you get one of our semi-dedicated hosting plans, you won't have to worry about silent data corruption as we use ZFS - an advanced file system which checks all of the files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a number of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no risk for any part of your content at any moment. In comparison, all the other file systems carry out checks only after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you can lose important info. As this isn't the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
