Backing Up Bare metal on Visualized DCs

-

hello,

i have virtualized domain controllers , know best way of backing these dcs.

a) if backup bare metal using windows default backup tool able (1) restore same on new virtual server on same host? or (2) virtual server on different host or (3) same host no virtual configurations anymore (if happens have abandoned visualization)

b) creating virtual server (disk) image better restoration on same host or on different host windows backup of the bare metal?

nb: understand importance of regular system state ups. have same hardware types/models.

thank you

hi sirchigs,

the best way backup using existing method of system state. if dc goes down never come backup, best method install fresh server , promote dc. can reset computer account , keep same name too.

there 1 supported way perform backup , restore of virtualized domain controller:

  1. run windows server backup in guest operating system.

if in hurry, win2012r2 supportes domain controller clonning.

you shouldn't use snapshots, manual vhd backups, export vm etc.

bare metal recovery should used when dcs in environment gone or data in existing ones not want. cause loose changed information\accounts. restoration should on identical hardware\config.

active directory, domain controller , restore(s)

qa:

a) if backup bare metal using windows default backup tool able

(1) restore same on new virtual server on same host? - yes

(2) virtual server on different host - yes, hw config needs similar

(3) same host no virtual configurations anymore (if happens have abandoned visualization) - might not work, due hardware differences.

b) creating virtual server (disk) image better restoration on same host or on different host windows backup of the bare metal?

- shouldn't use disk image recover dc.
