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.
8.3 Backup and Restore System Profiles
To recover from system failures, it requires restoring data and system configurations. Tape
backup and SmartSync are for restoring data, while system profiles are used for recovering
system configurations. System profiles are the backups of all system configurations, user
database and security information.
Backing Up System Profiles
To back up system configurations, please open the administration page and go to “Backup →
System Profile”. System profiles are saved manually or on a regular basis as defined on the
page. System profiles will be saved locally on HD. The current backups are displayed on the
lower page. To delete a system profile, check its check-box and click the “Delete” icon.
Recovering the system configurations when a disaster happens
If there is any system failure which causes corrupt system configurations, the first step is to
reset the system configurations to factory default. Go to the “Server → Shutdown” page.
Check the “Reset” configuration to factory default option and click the “Reboot” button. The
second step is to restore system configurations using one of the system profiles. Go to the
“Backup → System Profiles → Restore” page. Select a system profile and choose which part
