Changing the default cache folder for catalog files

Catalog files are normally stored in vaults. When working with catalog files, Acronis Backup & Recovery 11.5 may save them to a local folder on a managed machine or on a management server. This happens in the following cases:

• When an agent catalogues the data backed up to an unmanaged vault. The agent creates or updates the catalog locally and then copies it to the vault.
• When storing backups on a tape device. Because tape has a long latency for random accesses, the catalog of a tape-based vault is always stored on the machine where the tape device is attached.
• When browsing the data backed up to an FTP server in the Data view tab. During the browsing session, Acronis Backup & Recovery 11.5 maintains a full copy of the data catalog from an FTP server on a managed machine or on a management server. This is done for the purpose of fast access to the data catalog.

By default, a cache folder is located on the disk where the operating system is installed. Storing multiple catalog files in this location may result in the lack of free disk space. Therefore, you may want to change the folder path.

Changing the default cache folder

To do this, add a special parameter to the system registry in Windows or modify the MMS.config configuration file in Linux.

If the specified folder does not exist, Acronis Backup & Recovery 11.5 will automatically create it when creating or copying catalog files next time. If you are storing backups on a tape device, create the folder in advance so as not to catalog the data over again.

To specify a new cache folder in Windows:

1. Add the Catalog key to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\AMS\Configuration (on a management server) or HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\MMS\Configuration (on a managed machine).
2. Add the CatalogDir string value.
3. Specify a new folder path in the CatalogDir string value. The path must end with a backslash (\) and can be 32765 characters long.

To specify a new cache folder in Linux:

Add the following element inside the Configuration tag in /etc/Acronis/MMS.config:

<key name="Catalog">
<value name="CatalogDir" type="TString">"/home/Catalog/"</value>
</key>

So, the configuration file will look like:

<?xml version="1.0" encoding="UTF-8" ?>
<registry name="MMS">
<key name="Configuration">
...
<key name="Catalog">
<value name="CatalogDir" type="TString">"/home/Catalog/"</value>
</key>
</key>
</registry>

Where /home/Catalog/ is a new folder path. The path must end with a slash mark (/) and can be 32765 characters long.

Moving the catalog files

After changing a cache folder, Acronis Backup & Recovery 11.5 neither moves the catalog files to the new folder nor removes the old folder.

If your backups are stored on a tape device, move the catalog files to the new location so as not to catalog the data over again. Otherwise, you may let Acronis Backup & Recovery 11.5 create or copy the catalog files anew.

You may also want to delete the old folder. The default cache folder path is as follows:

• In Windows XP: %ALLUSERSPROFILE%\Acronis\AMS\AMS\Catalog (on a management server) or %ALLUSERSPROFILE%\Acronis\BackupAndRecovery\MMS\Catalog (on a managed machine)
• In Windows 2003: %ALLUSERSPROFILE%\Application Data\Acronis\AMS\AMS\Catalog (on a management server) or %ALLUSERSPROFILE%\Application Data\Acronis\BackupAndRecovery\MMS\Catalog (on a managed machine)
• In Windows Vista/7/2008/2008 R2: %PROGRAMDATA%\Acronis\AMS\AMS\Catalog (on a management server) or %PROGRAMDATA%\Acronis\BackupAndRecovery\MMS\Catalog (on a managed machine)
• In Linux: /var/lib/Acronis/BackupAndRecovery/MMS/Catalog/
