 Compacting - the compacting task deletes from the deduplication data store the blocks which

are no longer referred to. To learn more about compacting, see the "How deduplication works"

(p. 230) section.

 Idle - compacting is not running. You can start the compacting by clicking the Run

compacting link.

 Running - compacting is running. You can stop the compacting by clicking the Stop link.

 Compacting schedule - the compacting task scheduling parameters. Click the Compacting

schedule link to re-schedule the compacting task. Only the time events (daily (p. 80), weekly (p.

82), and monthly (p. 84) schedules) are available for setting up. The preset is: Start the task every

1 week on Sunday at 03:00:00 AM.

Statistics

This tab provides you with information about the original and backed data sizes on all the managed

vaults of the selected storage node.

Vaults

This tab displays a list of vaults managed by the selected storage node. To update the list of vaults

with the most recent information from the management server, click Refresh.

Indexing

This tab lets you examine the current status of indexing for the deduplicating vaults of the storage

node and review the date and time of the last run.

7.5.6.4 Configuring a storage node by using Acronis Administrative

Template

The following are the parameters of Acronis Backup Storage Node that can be set by using Acronis

Administrative Template. For information on how to apply the administrative template, see How to

load Acronis Administrative Template (p. 395).

Parameters related to compacting

As backups are deleted from a deduplicating vault, its deduplication data store (p. 230) may contain

unused data blocks (items) that are no longer referred to from any backup. The storage node

processes the data store to delete the unused items. This operation is called compacting. Compacting

is performed by the compacting task.

Every time the compacting task starts, the storage node determines whether to perform compacting.

To do this, the storage node:

1. Checks the size of the backed-up data that has been deleted from the vault since the last

compacting.

2. Uses the Compacting Trigger Rough Estimation Threshold parameter to determine whether this

size, relative to the size of the remaining backed up data, is significant.

3. If so, uses the Compacting Trigger Threshold parameter to determine whether the deduplication

data store contains a significant number of unused items. If so, the storage node performs

compacting.

The parameters are the following.
