Which features are supported by Server Synchronization

The following functions are supported:


Synchronization jobs can be scheduled weekday (including time). For example, you can only synchronize on Mondays and Fridays, or only on weekends, to reduce the burden on the network on weekdays.

WAN support (bandwidth can be set)

If the data is copied over a WAN line, not over the local network, it is recommended to set the bandwidth exactly (in Kbytes per second).

Permissions and attributes are copied (ACL)

Data is copied along with its authorizations and attributes. All POSIX ACL permissions are retained.

Owner, date and time are retained

Synchronizing the files preserves the original owner or date and time.

Data compression

Files are compressed before they are sent. This saves bandwidth and speeds up data transfer over the network.

Byte-level incremental replication

Performance is increased by copying only the bytes that have changed for this file since the last synchronization for large files.

Can also iSCSI Targets be synchronised?

Embedded server synchronisation software is a file system based data replication. iSCSI Targets are block based devices and therefore cannot be replicated using the software.

Installation media of euroNAS dies ….

If the installation drive dies (the drive on which you have installed euroNAS software), just install euroNAS on a new media.

New installation will automatically recognize and import the hardware, raid and shares.

Additionally if you have saved the settings before – you can restore them via system menu.

Also if you have perfomed the backup of your installation using the installation CD you can install this backup image on a new media. In this case all settings will be restored.

How can I replace failed drive on software raid?

If the drive fails in a redundant raid array (Raid 1, 5 or 6) just go under Software Raid - Raid Info and select option repair and follow the wizzard.

Alternatevly you can replace it by defining the replacement drive as hot spare in the software raid management. Rebuild will then start automatically.

How can I reach the server if I forget its IP Address?


Tthere are 3 possibilities to reach the server in this case:

Possibility 1

Connect the monitor on the server and check in menue the option network info – the IP Address will be shown there

Possibility 2

Try to reach the server using its name

Possibility 3

If the server is set to pool the IP Address via DHCP Server – you can check the IP Address in the DHCP Management Software

Guest users are unable to log in


User guest has been assigned to a share (under access control) – still the guests are unable to login to the share.


Windows users are automatically trying to log in with their own local user and password and not with account guest therefore the login attempt will be rejected.

If the share is mapped with user guest - no password then the user will be able to log in.

The easiest way is to enable guest account under network - domain and workgroup when joining the workgroup or domain. In this case all users that are not known to euroNAS will be treated as guests. In guest is assigned to a certain share this users will be able to log in automatically.
