AES 256 - an encryption algorithm which performs 14 rounds of encryption, making it virtually impossible to break, and thus guarantees the security of transmitted data. Completely resistant to all known attacks of linear and differential cryptanalysis.
Briefcase – the space within which the files of the user are stored. The data is coded with an AES 256 algorithm. The contents of the folder is synchronized on each computer on which the Xopero application is installed, within all computers of one user.
Backup – creating a backup copy of all important data, in order to restore them later in case of their damage of loss. Backup copies should be performed periodically and stored in a location different than the original. All backupsets are encrypted with an AES 256 algorithm, unless the option is turned off in the backupset wizard.
Backupsets (projects) – they represent files, which the user has backed up, by using the Xopero application. The files are distinguished by the devices form which they were backed up. All backupsets are encrypted with an AES 256 algorithm, unless the option is turned off in the backupset wizard.
Delta - a mechanism which detect differences in files, and allows to send only the modified parts of files, instead of full files than entire files. Xopero supports two types of Delta mechanisms:
- Differential - downloads and sends only the changes in the documents appearing since performing the last full backup.
- Incremental - downloads and sends only the changes in the documents appearing since the last backup, regardless of whether it was full or incremental.
The use of these technologies has a very beneficial effect on the backup and data restore speed and allows to save space on the server disk.
Devices – it represents one computer, operated by one Xopero application. This allows to maintain a cohesive structure of folders on different PCs in the process of backup and data restore. The number of devices is limited according to the product.
NAS (Network Attached Storage) - a technology which allows connecting disk storage resources directly to the network. This type of solution allows for simple configuration of data access from different points of the network.
QNAP - a company which produces high-quality NAS drives and disk arrays.
Proxy server (proxy, proxy gate) - server or software which establishes a connection on behalf of the user.
Volume Shadow Copy – a Windows service that allows you to create backup of opened files. This service is not available for Windows XP users.
Versioning - a mechanism through which the user has the ability to restore a previous version of the file, not necessarily the last one.
