Tape management database

Acronis Backup & Recovery 11.5 stores information about all tape devices attached to a machine 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 archives stored on tapes and equals approximately 10 MB per hundred archives. The database may be large if the tape library contains thousands of archives. In this case, you may want to store the tape database on a different volume.

To relocate the database in Windows:

1. Stop the Acronis Removable Storage Management service.
2. Move all files from the default location to the new location.
3. Add the registry key described below. Specify the new location path in the registry value ArsmDmlDbProtocol.

   Registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\ARSM\Settings

   Registry value: ArsmDmlDbProtocol

   Possible data values: Any string 0 to 32765 characters long.

   Description: Specifies the folder where the tape management database is stored.

4. Start the Acronis Removable Storage Management service.

To relocate the database in Linux:

2. Move all files from the default location to the new location.

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.
