Please review the answers below to your questions. If for some reason you still are not able to update on the Antivirus please send logs to support@open-e.com.

Question 1:

When using NTP server to maintain proper time & date, please
make sure you have proper Gateway and DNS settings for this to update automatically every 12hours.

Question 2:

Accessing the snapshot to restore, is done manually by selecting the files or directories from the Snapshot directory. Recommended reserved space for Snapshot is at least 10% of the total storage capacity of the data in use for current and future. The storage of all changes is independent of the file-system Open-E NAS-XSR uses on block-level.
Only when the snapshot is deleted / removed the changes are permanently transferred to the actual data volume. Through a separate share, which is only available for the administrator (or backup administrator), a complete backup of the dataset can be done. The Snapshot function is perfectly transparent for the users in the network. Only the administrator can work with the Snapshots.

Question 3:

Make sure your DNS settings are correct and updated to the latest NAS-XSR SMB version. "Select mirror" and choose one of the mirror servers nearest to your localization.

Option "Update interval" allows updating the virus database:
•Now
•Now and every hour
•Now and every 12 hours at 0:00,12:00
•Now and every 24 hours at 0:00
