Snapshot Storage
Specifies the location and initial size of the snapshot storage—a temporary file that is used when
backing up data by taking a snapshot. This file is deleted as soon as the backup is complete.
With the default settings, the snapshot storage is created in the temporary files folder of the
agent and initially occupies 20 percent of the space available on the volume containing that
folder. This size may then grow if more space is needed for the snapshot.
You may want to increase the initial size of the snapshot storage—or to place it on a different
volume—when experiencing problems with backing up data that changes extensively during
backup.
This parameter is used when creating a local backup plan. Changes to this parameter do not
affect already existing local backup plans.
This parameter has the following settings:
Path to the snapshot folder
Description: Specifies the folder in which to create the snapshot storage.
Possible values: Any string 0 to 32765 characters long
Default value: Empty string
An empty string means the folder %ALLUSERSPROFILE%\Application
Data\Acronis\BackupAndRecovery\MMS\Temp (in Windows XP and Server 2003)
or %PROGRAMDATA%\Acronis\BackupAndRecovery\MMS\Temp (in Windows Vista and later
versions of Windows).
You can specify a local folder on any volume, including a volume you are backing up.
Pre-allocated storage size (in Megabytes)
Description: Specifies the initial size of the snapshot storage, in megabytes.
Possible values: Any integer number between 0 and 2147483647
Default value: 0
If this setting is 0, the management server uses the Pre-allocated storage size (in percent)
setting.
The initial size will not exceed the available space minus 50 MB.
Pre-allocated storage size (in percent)
This setting is effective only when the Pre-allocated storage size (in Megabytes) setting is 0.
Description: Specifies the initial size of the snapshot storage as a percentage of the disk space
that is available at the time of starting the backup.
Possible values: Any integer number between 0 and 100
Default value: 50
If this setting is 0, the snapshot storage will not be created.
The initial size will not exceed the available space minus 50 MB.
Without the snapshot storage, taking snapshots is still possible.
The size of the snapshot storage does not affect the size of the backup.
Online Backup Proxy
Specifies proxy server settings for connection to Acronis Cloud Storage over the Internet.
This parameter has the following settings:
