Backup
Backup is a process of creating security copies of key data in order to recreate them after their loss or damage. Security copies should be stored in locations different than the original data.
All backups created by the Xopero application are incremental and differential. During first backup full data is sent, and later only differences which appeared in particular files since their last sending.
Xopero also supports data versioning, which means that the user can restore any of the previous file versions, not necessarily the last one.
Mechanism
All backups in the Xopero application are sent according to the same scheme. At the beginning - except where the Volume Shadow Copy option is enabled - each file is individually copied to a temporary location, where it is encrypted - unless this feature is disabled while creating the project - and divided into smaller parts. It is then sent to the user’s server disk. Backup can be performed using delta compression so that the application receives and sends only data modifications, or newly created documents. The Xopero application supports two types of delta backup:
- Differential - receives and sends only document changes, which appeared since performing the last full backup.
- Incremental - receives and sends only document changes which appeared since the last backup, regardless of whether it was full or incremental backup.
The use of these technologies in our application saves time and disk space while creating backups and restoring data from Xopero server.
Delta is a method of storing and sending data in a form of differences between particular file version, instead of full file versions.
Thanks to the delta mechanism, besides reducing the amount of sent files, we have also increased their security.
Backupset wizard
In order to create a new backup project, you have to start the backupset wizard, which can be done in 2 ways:
1. Click on Create new backupset in the Start tab in the Last completed section.
2. Click on New backupset in the My backupsets tab.
Choosing one of these options results in launching the backupset wizard, which is divided into two sections: Basic information and Advanced. First of them allows you to indicate data type and data of which backup you want to create, the second one allows you to choose advanced options which are to be applied during backup creation.
Depending on the chosen type of copy, the appearance of the Basic information tab is going to change, and some of the advanced options might be inactive.
It is required, for each project, to name it in a unique way within the user account.
