The size of the deleted data is 20 GB, and the size of the remaining data is 80 GB. The ratio of the
deleted to remaining data is thus 20 GB / 80 GB = 0.25, or 25 percent.
The storage node calculates the relative size of the remaining data as 100 percent – 25 percent =
75 percent.
Because this relative size is less than 90 percent, the storage node starts checking for unused
items.
Compacting Trigger Threshold
Description: Specifies the percentage of used items in the deduplication data store below which
compacting occurs.
Possible values: Any integer number between 0 and 100
Default value: 90
Since compacting is a resource-consuming operation, it should occur only when the number of
unused items is significant.
The Compacting Trigger Threshold parameter enables you to set up a balance between the extra
space required to store unused items and the compacting frequency. The larger the value of this
parameter, the fewer unused items are allowed in the data store, but compacting will likely be
more frequent.
The check is performed only after checking the percentage of the remaining backed up data in
the vault (see the Compacting Trigger Rough Estimation Threshold).
Other parameters
Log Cleanup Rules
Specifies how to clean up the storage node log.
This parameter has the following settings:
Max Size
Description: Specifies the maximum size of the storage node log folder, in kilobytes.
Possible values: Any integer number between 0 and 2147483647
Default value: 1048576 (that is, 1 GB)
Percentage To Keep
Description: Specifies the percentage of the maximum log size to keep on cleanup.
Possible values: Any integer number between 0 and 100
Default value: 95
Client Connection Limit
Description: Specifies the maximum number of simultaneous connections to the storage node by
the agents that perform backup, recovery, or operations with archives (such as validation,
replication, or cleanup).
Possible values: Any integer number between 1 and 2147483647
Default value: 10
Acronis Backup agents connect to the storage node to access its managed vaults during backup,
recovery, or to perform an operation with an archive. The Client Connection Limit parameter
determines the maximum number of such connections that the storage node can handle
simultaneously.
When this limit is reached, the storage node will use the backup queue (see the next parameter)
for the agents that are awaiting connection.
