Enable (or Disable) Index
Cache Sharing for a Job
Before You Begin
The catalog server option for the job is applicable only if the
MediaAgent performing the backup is configured for index
cache sharing.
To
enable (or disable) index cache sharing using catalog server:
From the CommCell Browser, select one of the following:
To backup a subclient, right-click the subclient to want to backup and
click Backup.
To backup a user-defined backup set or instance, right-click the backup
set you want to backup, click All Tasks, and click Backup All
Subclients.
To backup the default backup set, right-click the agent or instance
node, click All Tasks, and click Backup Default Backup Set.
For Lotus Notes iDataAgent,
to backup a partition, right-click the partition you want to backup, click
All Tasks, and click Backup Default Backup Set.
For Agents that do not have backup set or instance levels, to backup
all subclients, right-click the agent icon, click All Tasks, and
click Backup All Subclients.
If you chose a level higher than subclient (i.e., backup set, etc.), you
are prompted to confirm that you want to back up all the subclients below that
level. Click Yes.
If you want to adjust the granular restartability option for the backup
job, click Advanced from the Backup Options
window.
From the
Advanced Backup Options (Data) tab, select one of the following options.
Use shared profile if present with transaction logging for
index cache sharing along with the transaction logging feature for
granular job restartability. This option is enabled by default and
recommended for all configurations.
Use shared profile if present without transaction logging for index cache sharing without the transaction
logging feature. This option reduces the network traffic between the
MediaAgent and the Index Cache Server by limiting the amount of data
being transferred. This configuration is not recommended because if a
job fails or gets restarted, it will start from the beginning.
Use Transaction logging for the granular job restartability
feature. This option is designed for a standalone MediaAgent without an
Index Cache Server as it allows the job to restart from the last commit
point in the case of a power failure, system error or another unexpected
job termination.
None to disable index cache
sharing. When selected, the index cache is stored in the MediaAgent’s local
index cache only.
From the CommCell Browser, right-click the CommServe, click Control

Move an Index Cache
Before You Begin
For Unix MediaAgents, if the index cache
resides on a network share, you have to manually mount the drive containing
the index cache to the local machine to be able to create a shared index
cache. Also note down the local mount path.
Select Use Network Share if the index cache will reside on a network
share, and select Use MediaAgent Local Drive if the index cache will reside on
a local drive.
In the Index Cache Directory box, type the path to the index cache
directory or use the Browse button to select the path.
If the MediaAgent resides on a Network Share, click the
Change button.
In the Change
User Account dialog box, type the user account and password that must be
used to access the index cache and then click OK.
For Unix MediaAgents:
In the Index Cache Directory box, type the path to the index cache
directory or use the Browse button to select the path. If the index
cache resides on a network share, then this will be the path to network
index cache mounted locally.
Click OK to save the configuration.
If the index is moved from a local drive to a network share, a Confirm
prompt is displayed, asking you whether you wish to copy the
index cache. Click one of the following:
Yes to copy the index cache to the new index cache folder.
No to move the index cache without copying the index cache
folder. In this case subsequent jobs may result in index restore
operation from the media.
The index cache is moved to the new folder.
NOTES
It is important that you do not change the Name of the Profile when
moving a shared index cache.
On Windows MediaAgents, the original directory may have to be manually
deleted to free the disk space.
Index Cache can only be moved when no index jobs like Auxiliary Copy,
Disaster Recovery Backups, Deduplication Backups, etc. are running.
For unix MediaAgents, if the index cache
resides on a network share, you have to manually mount the drive containing
the index cache to the local machine to be able to create a shared index
cache. Also note down the local mount path.
Select Use Network Share if the index cache will reside on a network
share, and select Use MediaAgent Local Drive if the index cache will reside on
a local drive.
In the Index Cache Directory box, type the path to the index cache
directory or use the Browse button to select the path.
If the MediaAgent resides on a Network Share, click the
Change button.
In the Change
User Account dialog box, type the user account and password that must be
used to access the Index Cache and then click OK.
For Unix MediaAgents:
In the Index Cache Directory box, type the path to the index cache
directory or use the Browse button to select the path. If the index
cache resides on a network share, then this will be the path to network
index cache mounted locally.
Click OK to save the configuration.
Repeat the above steps on all the MediaAgents that share the
index cache. If this is not done, the index cache will be turned
offline after 30 minutes, and all the jobs accessing the MediaAgents that
share this index cache may fail as a result.

directory or use the Browse button to select the path. If the index
cache resides on a network share, then this will be the path to network
index cache mounted locally.
Click OK to save the configuration.
Click NO in the
Confirm prompt.
The index cache is relocated to the new folder.
Unshare a Shared Index Cache
Before You Begin
Ensure that the MediaAgent is not defined
as an alternate data path candidate in any of the storage policy copies. If
the MediaAgent is used as candidate, the system will automatically prevent
you from unsharing the index cache.
For Unix MediaAgents, if the index cache
resides on a network share, you have to manually mount the drive containing
the index cache to the local machine to be able to create a shared index
cache. Also note down the local mount path.
From the CommCell Browser, right-click the MediaAgent for which you wish
to unshare the shared index cache and then click Properties.
From the
Catalog tab, uncheck the Catalog Profile option. The index cache
is no longer shared.
If you were using a Network Share, then you will have to provide a local
path for the index cache. Perform one of the following:
For Windows MediaAgents:
Select Use Network Share if the index cache will reside on a network
share, or select Use MediaAgent Local Drive if the index cache
will reside on a local drive.
