ACRONIS BACKUP AND RECOVERY 10 ADVANCED SERVER SBS EDITION - UPDATE 3 User Manual page 336

When connecting to a registered machine, Acronis Backup & Recovery 10 Management
Server first uses the machine's network name—provided that the machine was added to the
management server by name.
If Second Connection Attempt is set to True and a connection to the machine by using its
network name has failed, the management server performs a second connection attempt,
this time using the latest IP address which was associated with that network name.
We recommend setting Second Connection Atempt to True only in networks which often
experience problems with their DNS servers, and provided that the machines' IP addresses
change infrequently—as in cases of fixed IP addresses or long DHCP lease times.
This setting has no effect on machines that were added to the management server by IP
address.
Offline Period Threshold (in seconds)
Description: Specifies the maximum interval, in seconds, between attempts to connect to a
registered machine which appears to be offline.
Possible values: Any integer number between 120 and 2147483647
Default value: 1800
Normally, the management server connects to each registered machine with a certain time
interval (see Period and Period-High Priority earlier in this section). When the management
server discovers that the machine is offline, it doubles this interval; it keeps doubling this
interval on each further attempt until reaching the value specified in
Offline Period Threshold. If the machine comes back online, the time interval becomes
normal again.
This approach aims at efficient use of the management server resources and reducing the
network load.
Backup
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 a Windows' temporary files folder
and occupies 50 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 backup policy and applies to all centralized backup plans
that will be based on this policy. Changes to this parameter do not affect already existing backup
policies (and their centralized backup plans).
This parameter has the following settings:
Snapshot Storage Path
Description: Specifies the folder in which to place the snapshot storage.
Possible values: Any string 0 to 32765 characters long
Default value: Empty string
An empty string means a temporary files folder, which is typically given by the TMP or TEMP
environment variable.
You can specify a local folder on any volume, including a volume you are backing up.
Snapshot Storage Absolute Size
