NAS credential issue when using recovery tab

Hi Everyone,

This is my first post. Hope you can help me with this issue. Thank you!

Today I upgraded from ATI 2019 to ATI 2020 and I'm having an issue related with my NAS credentials when navigating through my backup list by using the recovery tab. Currently I'm backing up some of my NAS folders to a USB HDD. When logging into my NAS by going into the backup task and selecting the NAS as origin I can logging and run the backup task perfectly fine by using my NAS credentials (I have a username called 'Backup' for this purpose), but when using the recovery tab and navigating through my backup list I can see ATI 2020 is using a different username called 'NetworkService' (by default, not entered by me) to try to login into my NAS (I have a QNAP NAS and I can see information about users who are logging in), thus it's not using my NAS username 'Backup' previously entered. This is giving me problems because I have some security rules in my NAS when using SAMBA, for instance X quantity of invalid logins will ban the IP, so basically it's banning one of my LAN IPs over and over again.

I went through the Knowledge Base https://kb.acronis.com/content/58004 and cleared the old NAS credentials by deleting registry key HKEY_CURRENT_USER\Software\Acronis\Connections\smb, then opened ATI 2020 and edited again my backup task, re-selected my NAS folder as origin, but the issue continues.

This is kind of different, since I'm able to login into my NAS and run backups perfectly fine, but it seems ATI 2020 is not using the same NAS credential on both sides (it only asked me to enter my credentials when going into the backup task, but not when going into the recovery tab). This behaviour was not happening to me in ATI 2019, that version was asking my NAS credentials and using the same NAS credential on both sides (backup task and recovery tab).

Any clues?

I have not had anything unusual happen with 2020, including beta testing. When I run recovery all I am asked for is the encryption password for the backup, the login credentials are remembered apparently remembered and sent to the NAS. Have not checked things from the NAS side. Long past my bed time so brain cells are not cooperating sufficiently for me to make an attempt to work out what ins happening.

You can observe the connections using the get-smbconnection powershell command on Windows.

As you can see, ATI running in interactive mode uses different user accounts from an SMB perspective. The backup task is using the Windows system user, while other UI functions use the interactive windows account (typically: "[ComputerName}/[UserName]". The UI seems to be able to use the Microsoft Account credentials stored in the Windows credential manager, this is why you didn't have to enter the credentials in the recover tab.

The backup task seems to store the NAS credentials separately because the way they are displayed in the powershell are different depending on the case. When the NAS is the source, the credentials are "/[UserName", when the NAS is the destination the credentials are "[NAS]/[UserName]"

By learning about which user is used for which purpose, you might be able to set up your NAS access rights for the appropriate users.
