Couldn't create the destination directory

[Oldman]

Continue to get "Couldn't create the destination directory" error. What do I do to correct this?

It's 99% of the times a problem with permissions. Is the program running as a service (under LocalSystem) and is the destination a network path?

After using Cobian backup for a long time I encounter the issue of "Couldn't create the destination directory" just now when copying to the NAS which I used before successfully so I don't suspect a rights issue in my situation, especially because the error message is that the "file, folder or volume name syntax is not correct". However if I look at the path that the program is trying to use: "\\SynDisk1\Backup M\Mail 2021-03-28 16;54;45 (Full)" I suspect the semicolons that are used in the path name. Can I setup Cobian in a way that it doesn't insert the semicolons?

I agree

I suspect the semicolons that are used in the path name.

It is unlikely

Can I setup Cobian in a way that it doesn't insert the semicolons?

You are right, the semicolon was not the issue. My Cobian runs as a service and I have users defined on my Synology NAS. Anybody who knows how to set-up security in a way that the Cobian service can write to the NAS?

1. Create a user on the NAS.
2. Create Share
3. Give user rights to Share with read / write access
4. If you use password access, and not access from AD, create a bat-file with the following content:
net use L: \\ 193.121.161.14 \ Backup /user:193.121.161.14\backup 987654321
I think you can figure out what and how.
Those. connect the network drive L c Share Backup (\\ 193.121.161.14 \ Backup)
user: 193.121.161.14 \ backup - created NAS user
987654321 - password.
Place this file in the list of tasks. And voila.
Something like that.

NAS are a little difficult when running as a services because the have its own user which is often cached when your Windows user logs in but not when using the program as a service. Paltus solution is similar to the one I use.
