I have found none, so I have implemented it by myself: https://fex.rus.uni-stuttgart.de/snaprotate.html In contrast to Netapp, with snaprotate the local host administrator can create a snapshot at any time or by cronjob. Example: root@fex:~# snaprotate single 3 /local/home Create a readonly snapshot of '/local/home' in '/local/home/.snapshot/2017-09-09_1518.single' Delete subvolume '/local/home/.snapshot/2017-09-09_1255.single' root@fex:~# snaprotate -l /local/home/.snapshot/2017-09-08_0000.daily /local/home/.snapshot/2017-09-09_0000.daily /local/home/.snapshot/2017-09-09_1331.single /local/home/.snapshot/2017-09-09_1332.single /local/home/.snapshot/2017-09-09_1400.hourly /local/home/.snapshot/2017-09-09_1500.hourly /local/home/.snapshot/2017-09-09_1518.single root@fex:~# crontab -l | grep snaprotate 0 * * * * /root/bin/snaprotate -q hourly 2 /local/home 0 0 * * * /root/bin/snaprotate -q daily 3 /local/home 0 0 * * 1 /root/bin/snaprotate -q weekly 1 /local/home -- Ullrich Horlacher Server und Virtualisierung Rechenzentrum TIK Universitaet Stuttgart E-Mail: horlacher@xxxxxxxxxxxxxxxxxxxx Allmandring 30a Tel: ++49-711-68565868 70569 Stuttgart (Germany) WWW: http://www.tik.uni-stuttgart.de/ REF:<20170822132208.GD14804@xxxxxxxxxxxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
