Tape management database

The information about all tape devices attached to a machine is stored in the tape management database. The default database path is as follows:

• In Windows XP/Server 2003: %ALLUSERSPROFILE%\Application Data\Acronis\BackupAndRecovery\ARSM\Database.
• In Windows Vista and later versions of Windows: %PROGRAMDATA%\Acronis\BackupAndRecovery\ARSM\Database.
• In Linux: /var/lib/Acronis/BackupAndRecovery/ARSM/Database.

The database size depends on the number of backups stored on tapes and equals approximately 10 MB per hundred backups. The database may be large if the tape library contains thousands of backups. In this case, you may want to store the tape database on a different volume.

To relocate the database in Windows:

1. Stop the Removable Storage Management service.
2. Move all files from the default location to the new location.
3. Find the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\ARSM\Settings.
4. Specify the new location path in the registry value ArsmDmlDbProtocol. The string may contain up to 32765 characters.
5. Start the Removable Storage Management service.

To relocate the database in Linux:

1. Stop the acronis_rsm service.
2. Move all files from the default location to the new location.
3. Open the configuration file /etc/Acronis/ARSM.config in a text editor.
4. Locate the line <value name="ArsmDmlDbProtocol" type="TString">.
5. Change the path under this line.
6. Save the file.
7. Start the acronis_rsm service.
