Use this dialog box to view or modify the index cache sharing and retention criteria.
Catalog Profile
Select this option to use a shared catalog configuration for index cache sharing.
Specifies that the MediaAgent uses a Index Cache Server profile for index cache sharing. When selected, a copy of the MediaAgent's index cache is stored in the Index Cache Server. This is in addition to the local index cache stored in the MediaAgent's index cache directory.
Name
Specifies the name of the Index Cache Server profile. To change, select a profile from the list of available Index Cache Server profiles.
When selected, specifies that the MediaAgent uses a network share for index cache sharing.
Name
Specifies the name of the network share profile. To change, select a profile from the list of network share profiles available. When selecting this option the Index Cache Directory must point to the network share directly.
Click to create or edit Index Cache Server or shared Index Cache profiles for index cache sharing. The Shared Catalog Configuration dialog box is displayed.
Select the type of index cache directory.
Use Network Share
Select this option if the index cache directory is located on a UNC path or Network Share.
Use MediaAgent Local Drive
Select this option if the index cache directory is located on a local drive on the MediaAgent computer.
Indicates the directory in which index data resides.
You can designate a new directory for the index cache. The new directory can either be a non-existent directory (will be created by the MediaAgent software), or an empty existing directory.
When you designate another directory for index cache, the MediaAgent moves the existing cache contents and directs all new cache entries to the specified directory. However, note that the Windows MediaAgents copies the existing cache contents and hence the original directory may have to be manually deleted to free the disk space.
![]() |
Do not specify or relocate a Media Agent's index cache to a directory residing on a compressed drive. |
Do not specify the root directory as the index cache directory in a Unix MediaAgent, | |
For security reasons, the necessary login and password must be provided when the Index Cache location is modified. |
Click to establish or change the designated Index Cache Directory.
Specifies the user account details to access the index cache directory.
Click to establish or change the user account and password details.
When selected, the index is written to the local disk first and at commit points uploaded to the Network share. This option is highly recommended when configuring Index Cache on a network share as it will avoid failures due to network disruptions/failures while writing to the index in the network share.
When selected, this MediaAgent will be available to be configured as a data path candidate in the Copy Data Path Candidates dialog box which can be accessed from the Copy Properties (Data Paths) dialog box.
![]() |
Ensure that all the MediaAgents that will be
configured as data path candidates, point to the same network share
and the same folder within this network share for its index cache
location.
If you have both the Unix and Windows MediaAgents pointing to the same folder, make sure that the files and folders are accessible to both these operating systems. |
Displays the offline reason, when the status of the selected index cache is offline.
Index retention time in days
Specifies the number of days to retain the index cache. Whenever a backup is initiated, the MediaAgent removes all index files that have not been accessed within the specified number of days.
Minimum Free Space (MB)
Specifies the total amount of free space that must be available at all times in the index cache. If necessary, use the space to modify the amount of minimum free space.
Index cleanup percent
Specifies the disk percentage used to remove the index cache.
Whenever a backup is initiated, the MediaAgent checks for the available disk space in the disk housing the index cache. If the amount of used disk space exceeds the specified percentage, the MediaAgent removes index files in the index cache on a least recently used basis until the disk space is equal to the specified percentage. However, keep in mind that the index retention time will not be taken into consideration during this process.
Free Space Warning (MB)
Specifies the amount of free space in the index cache at which a warning must be generated. If the amount of free space falls below the specified amount, the MediaAgent generates an event message and generates the MediaAgents (Disk Space Low) alert, if configured.
![]() |
The above parameters are not applicable for NetWare MediaAgents. Ensure that you have sufficient disk space on the NetWare volume that hosts the index cache before performing data protection operations. |
