Unable to set network drive path as Backup storage path

Hi Team, I am new on this platform, however, when I tried to add network drive path with double slashes at the beginning \192.168.200.20\VMs\urbackup as Backup storage path, it gives me error: (err_long_create_failed). The filename, directory name, or volume label syntax is incorrect. (code: 123)
UrBackup Server has trouble storing files to backup storage with the maximum file name length it was compiled with (255 UCS-2 code points/UTF-16 with max 2*255 bytes). There might be issues when backing up files/folders with long file name.
