两年前，我尝试进行 lxc 备份，但出现某些快照失败的错误。
运行测试命令
lxc export backup /tank/local/lxd/backups-temp/backup_test.tar.gz -v
错误信息：
Error: Create backup: Backup create: Snapshot "sunday-2019-12-01" in storage but not expected

我找到了这个文件夹并删除了它。但它仍然不起作用。所以它应该在其他地方。我花了很多时间才弄清楚。有人能帮我解决这个问题吗？
答案1
我通过自己的解决方案找到了它。
如果您在 lxc 快照列表中看不到旧备份，则可以使用以下解决方案。然后运行此命令：
1. 列出所有快照
zfs list -t snapshot
2.获取所有列表：
NAME USED AVAIL REFER MOUNTPOINT
tank/lxd/containers/backup@snapshot-sunday-2019-12-08 103M - 816M -
tank/lxd/containers/backup@snapshot-sunday-2019-12-15 71,4M - 819M -
tank/lxd/containers/backup@snapshot-sunday-2019-12-22 70,3M - 822M -
tank/lxd/containers/backup@snapshot-sunday-2019-12-29 67,4M - 824M -
tank/lxd/containers/backup@snapshot-sunday-2020-01-05 60,1M - 828M -
tank/lxd/containers/backup@snapshot-sunday-2020-01-12 77,3M - 834M -
tank/lxd/containers/backup@snapshot-sunday-2020-01-19 83M - 838M -
tank/lxd/containers/backup@snapshot-sunday-2022-01-23 100M - 44,6G -
tank/lxd/containers/backup@snapshot-sunday-2022-01-30 89,2M - 44,6G -
tank/lxd/containers/backup@snapshot-sunday-2022-02-06 94,1M - 44,6G -
tank/lxd/containers/backup@snapshot-sunday-2022-02-13 91,3M - 44,6G -
3. 销毁方法如下：
sudo zfs destroy tank/lxd/containers/backup@snapshot-sunday-2019-12-15
sudo zfs destroy tank/lxd/containers/**snapshot name**
