my UrBackup server 2.0.38 is installed on Slackware64 14.2.
I have nearly 30 clients installed in the same network, all running version 2.0.36 in Windows7 or Windows10, with NTFS file system.
Last Friday I’ve installed the clients running the msi installer (with tray icon).
Then I discovered the clients from server console. All clients were found and added to client’s list.
I tried to to an initial full file backup for all clients, but some of them give me a generic message “Starting backup failed” in the server console.
Today some clients are connected to the server, others are not.
If I try to do a backup from command line I receive this error: "Error starting backup. No backup server found."
Windows Firewall has a rule dedicated to “UrBackup Client Backend”, created by the installer.
All Windows clients has Trend Micro Worry-Free Standard v9, but also the clients that are working well.
Thanks in advance
