作为一名 DBA，深知备份的重要性，以及备份可用性的检查的重要性。
今天来检查一下设置好的备份策略有没有被正常地执行。

远程到家里的 mac mini，可以看到最新的时间戳。

这里最新的文件是 3 月 19 号的，是因为过去两天没有手动打开手机上的 MT-Photos app，刚刚备份了增量数据就没问题了。
文档资料
Nextcloud 里的备份文件夹
看一下文件夹的时间戳，没问题。
服务器上 Nextcloud 的备份

没有新的文件，说明都正常 rsync 复制了。
两周前新增加了放置于 Google Drive 的冷备
订阅了 Google AI Pro，有 2T 的 Google Drive 空间，利用一下。
export GPG_TTY=$(tty)
cd /Users/jinhuaiyao/Nextcloud/
tar -czf - Personal | gpg -c --cipher-algo AES256 | split -b 10G - /Users/jinhuaiyao/Downloads/Nextcloud.Personal.tar.gz.gpg.
tar -czf - Config Learning Reading | gpg -c --cipher-algo AES256 | split -b 10G - /Users/jinhuaiyao/Downloads/Nextcloud.Others.tar.gz.gpg.
把最重要的 4 个文件夹打包后用 gpg 加密，然后分割成 10G 一个的文件，上传到 Google Drive，作为冷备，增加一份保障。
就这样。
