What does Quick Synchronization mean?
When SmartSync is performing the second task, we can choose the Quick Synchronization option.
By selecting this option during synchronization, SmartSync will first check the file lists on both the source server and the
destination server. Then, it checks the modify time and file size of those files. If the results of both items are identical, the system
will simply bypass the synchronization of those sets of files and step to the next sets files. Thus it reduces the loading on the
network bandwidth and the processing time.
What solutions for remote backup does SURETE currently provide?
SURETE's solution for remote backup is SmartSync.
Just like the other NAS storage systems on the market, current synchronization mode is remote mirroring. That is the client-side
server can use SmartSync to make a mirrored image on the server side to achieve remote backup.
Does SmartSync support data synchronization from desktop to SURETE?
SmartSync currently supports data synchronization only from SURETE to other SURETE servers. We may consider implementing
data synchronization from Windows platform to SURETE at the second stage.
What is the minimum hardware spec required by SmartSync?
Because SmartSync is a resource-consuming task, SURETE requires at least 256MB add-on RAM.
Sometimes the SmartSync task will be terminated by a reason "memory low", what's the
possible cause?
Because SmartSync is a memory-consuming operation, memory utilization rate is critical when launching this task. When SURETE
detects the free memory is low, the program will terminate the synchronization task. To avoid this situation, we will suggest
checking following configuration or timing before launching SmartSync task.
1. Add-on RAM. 512 MB is suggested while 256 MB is minimum.
2. Set the SmartSync task to perform at non-rush hour to avoid memory conflict with routine network services.
3. Set a proper SmartSync source path. If the SmartSync source includes up to millions files/directories, that will occupy most of
the memory capacity when creating check list, it is suggested assigning the source path in multiple sub-directory in different
tasks.
What protocol is used for SmartSync? Is it CIFS/SMB, FTP or NFS network protocols?
SmartSync does not use CIFS/SMB, FTP or NFS as its communication protocol. It is based on SSL over TCP/IP. This also means
SmartSync has its own security policy and won't reference to SMB, FTP or NFS security setting.
Which part of SURETE will be mirrored to SmartSync Point? Data, Share Setting, ACL setting or
User database?
SmartSync feature focuses on "Data" part remote backup. Thus only Data and ACL setting in the Data will be synchronized to
remote servers, it does not synchronize User database and Share setting information to the SmartSync point. (Please refer to the
FAQ section "Backup". SURETE provides an advanced feature to Backup/Restore system configuration/User Database/Share
setting in Backup -> System Profiles page)
If I use firewall or NAT device in my network environment. Which ports have to be opened for
SmartSync tasks?
The default port number are 873 and 22, you have to open these two ports for SmartSync tasks.
