No, I want in EVERY directory of the sourcetree a subdirectory named snapshot, example: framstag@fex:/sw/share: ll .snapshot a*/.snapshot a*/*/.snapshot drwxrwxrwx root root - 2017-08-22 16:10:01 .snapshot drwxrwxrwx root root - 2017-08-22 16:10:01 aggis-1.0/.snapshot drwxrwxrwx root root - 2017-08-22 16:10:01 aggis-1.0/bin/.snapshot drwxrwxrwx root root - 2017-08-22 16:10:01 aggis-1.0/man/.snapshot (this is on a Netapp NFS volume) btrfs-snap creates a snapshot directory tree on a different path. -- Ullrich Horlacher Server und Virtualisierung Rechenzentrum TIK Universitaet Stuttgart E-Mail: horlacher@tik.uni-stuttgart.de Allmandring 30a Tel: ++49-711-68565868 70569 Stuttgart (Germany) WWW: http://www.tik.uni-stuttgart.de/ REF:
