Nextcloud Virtual FIles


we have installed the Nextcloud Client on an Urbackup client (2.5.24)

The server has now successfully backed up the PC, but displayed the entire Nextcloud folder as an error.

Error getting complete file “jxxVAt3JawS9urIXSsyi|C/Users/test/Nextcloud/10/2.pst” from AAA01PC01. Error code: CANNOT_OPEN_FILE (3)

Should I exclude the Nextcloud folder and back it up differently or is there a way to back it up or skip the virtual files that are not on the PC?
