euroNAS Server Synchronization, a built-in feature of euroNAS NAS Software, offers an advanced tool, with which data can be transferred locally or over long distances reliably and quickly, and if needed it can be easily restored without flooding the network with too much traffic.
Configuration is pretty simple and straight forward. Jobs can be set to run on a scheduled time or single jobs can be created.
First you need to define the shares you wish to replicate
To do this go to
Synchronization - Replication Shares
Then go to
Synchronization - Settings
And enter IP addresses of the servers that you wish to replicate.
IMPORTANT: Since the IP Addresses are used for security who can access the share all IP Addresses of the other servers needs to be entered – even if you don’t wish to use all addresses for replication. If not all are defined it is possible that connection gets refused.
Define also the share on which the synchronization logs will be saved.
Also you have a possibility to define additional options
Bandwidth – with this option set the replication will only use bandwidth defined
Data Compression – data will be compressed before it gets send to other server. This option makes sense if data is copied via VPN with lower bandwidth
Copy permission (ACL) – in this case ACLs of the files and folders will also be replicated
- Instant copy will make replication faster – in this case file differences will not be first copied on to the target share and then pasted to the file but immediately pasted. This saves space on the target server and also speeds up the replication
Resolve UID/GID – with this option euroNAS will try to resolve User / Group IDs into names when transferred
elete files that are not existing on source – If selected replication software will always check if the files on the target server exist on the source server. If they don’t exist they will be automatically deleted.
If this option is not selected it is possible that over time the target share gets full.
To configure scheduled synchronization go to Synchronization –
Start sync / create schedule and select
You can now decide if data should be replicated daily or hourly (for example every 1 or 4 hours).
Assign a name to the replication job and decide at which time and weekdays the job should be started.
If you wish to run hourly sync jobs you only need to enter the name of the job and severity.
Select source server and target server (if you wish to copy locally from one share to another you can select your local server).
You can now define source and target share for the synchronization.
Sync via snapshot should be selected if data copied is in use (for example virtual images) – in this case before sync job is issued snapshot of the data will be created and copied (instead of live data) – in this case data consistency will be much better than with standard copy.
Now everything is configured and you can see the jobs and their current status in the main menu.
