Acronis problem by absent SMB1 protocol on recent Win10 installation and older NAS devices

I started to build a new Win10 installation and installed also an unused ATI 2019 license to backup steps in case something goes wrong. I noticed I could not access my NAS (D-Link DNS-320 where backups are recorded from all computers in the home since years).

There were 2 problems:

1) I could not create a backup though I used the ip-address and credentials for the NAS which worked on other older PCs with Acronis True Image versions

2) And I could not access the NAS content in Windows Explorer with the elsewhere working credentials.

After many tries I found the solution here:

Brandnew Windows installations apparently dont't offer smb1 protocol by default any more, but older NAS devices apparently use it. So after activating smb1 protocol as recommended  (Windows-Powershell as administrator)

Du musst lediglich die Windows PowerShell mit administrativen Rechten öffnen und folgenden Befehl eingeben:

SMBv1 aktivieren per PowerShell

Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol

Safety issues with smb1 on my home network?

Should I change to FTP?

Franz, Microsoft dropped using SMB 1.0 some years back when build 1709 was released for Windows 10 - this was due to security exposures in that protocol version.

If your older NAS only supports SMB 1.0 and doesn't offer any option for using 2.0 or higher, then the best option is to ensure that there is no external access to that NAS, along with using dedicated user accounts (from the NAS) for any interactions with it, where there are no matching accounts configured for Windows.

FTP used by all current Acronis home products is also insecure with no support for SFTP so isn't any more secure than SMB 1.0 and would restrict backup files to maximum 2GB sizes due to FTP limitations!
