Data corruption is the damage of info due to various hardware or software problems. After a file gets corrupted, it will no longer work as it should, so an app 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 data getting harmed without any identification by the system or an admin, which makes it a serious problem for web hosting servers as failures are more likely to occur on larger in size hard disks where considerable volumes of info are kept. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is likely that the bad file will be treated as a good one and it'll be copied on all drives, making the harm permanent. Lots of the file systems that operate on web servers these days often are unable to locate corrupted files instantly or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the data uploaded in each and every cloud hosting account that is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We will store your information on a large number of SSD drives which work in a RAID, so the very same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged copy from a different drive from the RAID. No other file system uses checksums, so it is possible for data to be silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption because all our storage servers make use of the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of every single file. When you upload content to your account, it will be placed on several redundant drives working in a RAID i.e. the files shall be the same on all disk drives. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, and if it finds a mismatch, which will indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, lengthening 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.
