Please run
grep -ri dump /etc/psa/psa.conf
and make sure that the folders mentioned in the constant definitions exist in the backup path and are writeable by psaadm owner and group.

Example:

# grep -ri dump /etc/psa/psa.conf
DUMP_D /backup
DUMP_TMP_D /tmp

# /var/lib/psa/dumps]> ls -la
total 12
drwxr-x--- 3 psaadm psaadm 4096 Dec 21 08:39 .
drwxr-xr-x 3 root root 4096 Dec 21 08:39 ..
drwxr-x--- 2 777 root 4096 Apr 1 2020 tmp

The "backup" folder is missing. In that case, create it:

# mkdir /var/lib/psa/dumps/backup
# chown psaadm:psaadm /backup
# chmod 755 /backup

Permission is ok and directory exist, but have the same error:
"Unable to back up files from /var/www/vhosts/example.com owned by system user. Error: Failed to create archive"
