Hi,
lxd-snapper is a tool that takes snapshots.schedule to the next level - it’s a fancy wrapper for lxc snapshot & lxc delete that supports rich, Borg-style retention policies and hooks:
hooks:
on-snapshot-created: 'zfs send ...'
on-snapshot-deleted: 'ssh ... zfs destroy ...'
policies:
all-containers:
keep-hourly: 6
keep-daily: 5
keep-weekly: 4
keep-monthly: 3
keep-yearly: 2
storages:
included-instances: ['nextcloud']
keep-last: 60
Just prepare a snapshotting policy, setup a cronjob, and enjoy your containers!
