VMware Snapshot

記錄一下

Best practices for using snapshots in the vSphere environment (1025279)
https://kb.vmware.com/s/article/1025279

1. Do not use snapshots as backups.
2. Maximum of 32 snapshots are supported in a chain. However, for a better performance use only 2 to 3 snapshots.
3. Do not use a single snapshot for more than 72 hours.
4. Ensure that there are no snapshots before:
   4.1 Performing Storage vMotion in vSphere 4.x and earlier environments.
   4.2 Increasing the virtual machine disk size or virtual RDM.

Windows 的 Break 按鍵

Dell Latitude 7470 之後的 NB 都沒有 Break 按鍵
替代的組合按鈕

Ctrl + Fn + S

或

Ctrl + Fn + B

先前習慣使用的 『視窗鍵 + Break 』
則是要用 『視窗鍵 + Ctrl + Fn + B』
