SmartSync – NAS-to-NAS Data Replication
Step 3 is to complete the task settings. On the page you should
provide the task name, select the target folder to receive
data, specify the schedule and configure the SmartSync
options.
Step 4 is for confirmation, showing the brief information of the
task settings.
The SmartSync Options
When setting up a SmartSync task, you will see the following
SmartSync options.
• Compress the data stream during data transmission: when
checked, it will compress data before transmitting to the
SmartSync server. Sometimes it will make it faster to
complete a task. However, it takes extra CPU time to
compress data and may have performance penalty if
compression ratio is low.
• Contain security information: when checked, it will send
ACL information to the SmartSync server.
• Bandwidth control: limits the maximum bandwidth for the
task.
• Include/exclude file pattern: for excluding or including
certain file types in the synchronization. For example, to
exclude WORD files, type
-*.doc;
. To exclude all WORD
files except those beginning with abc, type
+abc*;-
*.doc;
.
• Perform quick synchronization: quick synchronization will
only check file date, time and size when matching files,
instead of checking block-by-block. It will speed up the
synchronization a lot, while taking the risk that files might
not be made identical.
• Generate transaction logs: when checked, it will record
which files are added, updated or deleted during the
data replication. The transaction logs are displayed on the
SmartSync
Summary page.
