Description Paul McAuley 2021-03-05 20:41:00 UTC

I have configured my backups to a SMB network share using Deja-Dup/Duplicity. The SMB location was mapped as a Network Folder through Dolphin. Deja-Dup backs up to a SMB directory with hundreds of files.

The problem is that when a backup is being performed to the network I cannot use Dolphin. It does not open initially and will hang for many seconds before opening. When open, Dolphin becomes unresponsive.

How are you accessing the SMB location?

1. Via a smb://[something] URL
2. Via a kio-fuse path 
3. Via a local path because the network location been manually mounted somehow
4. Something else?

Sharing the URL of the network location would be helpful.

I have specified in Deja-dup the Network Location smb://192.168.1.254/usb1/paul_backup/opensuse/

I also have smb://192.168.1.254/usb1 mapped as a network location in Dolphin.

When you say that it's mapped as a network location Dolphin, what exactly do you mean? Is that location configured as an entry in the Places panel?

Also, do you have kio-fuse installed? `zypper info kio-fuse` will tell you.

I mean I added it with the "Add Network Folder" wizard in Dolphin and it appears under "Network". I have not mounted the location.

I do not have kio-fuse installed.

Thanks. I got confused by your use of the word "mounted" because no local mounting is actually happening.

Comment 6 Paul McAuley 2021-04-17 16:38:13 UTC

Some more information -- duplicity uses the gvfsd-smb process to access smb. This is a GNOME library so perhaps is not related to KDE.

Comment 7 Nate Graham 2021-04-19 16:20:45 UTC

Probably, though Dolphin still shouldn't hang.
