Hiki iā LXD ke hana i nā kiʻi paʻi kiʻi a hoʻihoʻi i ke kūlana pahu mai ia mau mea.
No ka hana ʻana i kahi snapshot, e holo i kēia kauoha:
lxc snapshot alp snapshot1ʻO ka hui lxc snapshot ʻaʻohe kī i loaʻa list, no laila, e nānā i ka papa inoa o nā snapshots pono ʻoe e hoʻohana i ke kauoha e hōʻike ana i ka ʻike maʻamau e pili ana i ka ipu:

Snapshots:

lxc restore alp snapshot1Hoʻohana ʻia kēia kauoha e holoi i kahi kiʻi. E ʻoluʻolu, ʻaʻole like ka syntax kauoha me nā mea ʻē aʻe a pau; pono ʻoe e kuhikuhi i kahi slash i mua ma hope o ka inoa pahu. Inā haʻalele ʻia ka slash, a laila ua unuhi ʻia ke kauoha e holoi i kahi kiʻi kiʻi ma ke ʻano he kauoha e holoi i kahi pahu!
lxc delete alp/snapshot1Ma ka laʻana ma luna, ua nānā mākou i nā mea i kapa ʻia ʻo stateless snapshots. Loaʻa iā LXD kekahi ʻano paʻi kiʻi - stateful, e mālama i ke kūlana o kēia manawa o nā kaʻina hana a pau i loko o ka ipu. Aia kekahi mau hiʻohiʻona hoihoi a pono e pili ana i nā kiʻi kiʻi mokuʻāina.
He aha hou aʻe?
- Loaʻa kahi module no nā mea hoʻomohala Python e hāʻawi ana i kahi API i LXD
