Individual server: Backing up data¶

The versiondog system offers the option of backing up the server archive data manually or automatically at regular intervals using a batch file.

Prerequisites¶

To perform a data backup of the server archive, the following mandatory prerequisites must be met:

The user who performs the data backup manually must have administrative rights on the server system.
The VDog MasterService must be terminated before the data is backed up.
The PostgreSQL database system (PostgreSQL.exe application) is terminated with the VDog MasterService. For security, you can check this in the Service Control Manager.

If these requirements are not met, the server archive may be destroyed and data may be lost.

Warning

The system is not available during the data backup. It is recommended to perform the data backup during off-peak times, for example at night or at weekends.

Options for saving storage space:

The VD_TMP_VD directory in the server archive only contains temporary files. Back up the server archive without the VD_TMP_VD directory.
The vdServerArchive directory can be compressed before backing up. A corresponding ZIP application must be installed for compression.

Backing up data manually¶

Warning

If you use a remote archive, you must always back up both the remote archive and the local server archive.

Local archive¶

Copy the local directory vdServerArchive to the desired storage location, e.g. to an external hard disk.

Remote archive¶

Copy the vdServerArchive directory of the remote share to the desired storage location, e.g. to an external hard disk.

Backing up data automatically¶

You can back up the vdServerArchive directory automatically by creating a batch file and executing it at a specific time using the Windows Task Scheduler.

Example: Backup.bat file¶

Info

To use the batch file from the example for your system, adapt all path specifications in the file to your system.
